Windows Server 2008 Foundation Network Guide A foundation network is a collection of network hardware, devices, and software that provides the core services for your organization's information technology (IT) needs. A Windows Server foundation network provides you with many benefits, including the following. • Core protocols for network connectivity between computers and other Transmission Control Protocol/Internet Protocol (TCP/IP) compatible devices. TCP/IP is a suite of standard protocols for connecting computers and building networks. TCP/IP is network protocol software provided with Microsoft® Windows® operating systems that implements and supports the TCP/IP protocol suite. • Automatic IP addressing with Dynamic Host Configuration Protocol (DHCP). Manual configuration of IP addresses on all computers on your network is time-consuming and less flexible than dynamically providing computers and other devices with IP address leases from a DHCP server. • Name resolution services, such as Domain Name System (DNS) and Windows Internet Name Service (WINS). DNS and WINS allow users, computers, applications, and services to find the IP addresses of computers and devices on the network using the network basic input/output system (NetBIOS) name or Fully Qualified Domain Name of the computer or device. • A forest, which is one or more Active Directory domains that share the same class and attribute definitions (schema), site and replication information (configuration), and forest-wide search capabilities (global catalog). • A forest root domain, which is the first domain created in a new forest. The Enterprise Admins and Schema Admins groups, which are forest-wide administrative groups, are located in the forest root domain. In addition, a forest root domain, as with other domains, is a collection of computer, user, and group objects that are defined by the administrator in Active Directory Domain Services (AD DS). These objects share a common directory database and security policies. They can also share security relationships with other domains if you add domains as your organization grows. The directory service also stores directory data and allows authorized computers, applications, and users to access the data. • A user and computer account database. The directory service provides a centralized user accounts database that allows you to create user and computer accounts for people and computers that are authorized to connect to your network and access network resources, such as applications, databases, shared files and folders, and printers. A foundation network also allows you to scale your network as your organization grows and IT requirements change. For example, with a foundation network you can add domains, IP subnets, remote access services, wireless services, and other features and server roles provided by Windows Server® 2008 and Windows Vista®. 4

About this guide This guide is designed for network and system administrators who are installing a new network or who want to create a domain-based network to replace a network that consists of workgroups. The deployment scenario provided in this guide is particularly useful if you foresee the need to add more services and features to your network in the future. It is recommended that you review design and deployment guides for each of the technologies used in this deployment scenario to assist you in determining whether this guide provides the services and configuration that you need.

Network hardware requirements To successfully deploy a foundation network, you must deploy network hardware, including the following: •

Ethernet, Fast Ethernet, or Gigabyte Ethernet cabling

• A hub, Layer 2 or 3 switch, router, or other device that performs the function of relaying network traffic between computers and devices. • Computers that meet the minimum hardware requirements for their respective client and server operating systems. Note This guide depicts the use of four server computers. In some cases, such as on small networks, you can use fewer servers. For example, you can install DHCP and WINS on the same server rather than on separate servers.

What this guide does not provide This guide does not provide instructions for deploying the following: •

Network hardware, such as cabling, routers, switches, and hubs

•

Additional network resources, such as printers and file servers

•

Internet connectivity

•

Remote access

•

Wireless access

•

Client computer deployment

Note Client computers running Windows Vista and Windows XP are configured by default to receive IP address leases from the DHCP server. Therefore, no additional DHCP or Internet Protocol version 4 (IPv4) configuration of client computers is required.

Technology Overviews The following sections provide brief overviews of the required and optional technologies used to create a foundation network.

Active Directory Domain Services A directory is a hierarchical structure that stores information about objects on the network. A directory service, such as AD DS, provides the methods for storing directory data and making this data available to network users and administrators. For example, AD DS stores information about user accounts, such as names, passwords, phone numbers, and so on, and enables other authorized users on the same network to access this information.

DNS DNS is a name resolution protocol for TCP/IP networks, such as the Internet or an organization network. A DNS server hosts the information that enables client computers to resolve easily recognized, alphanumeric DNS names to the IP addresses that computers use to communicate with each other.

DHCP DHCP is an IP standard for simplifying management of host IP configuration. The DHCP standard provides for the use of DHCP servers as a way to manage dynamic allocation of IP addresses and other related configuration details for DHCP-enabled clients on your network. Every computer on a TCP/IP network must have an unique IP address. The IP address (together with its related subnet mask) identifies both the host computer and the subnet to which it is attached. When you move a computer to a different subnet, the IP address must be changed. DHCP allows you to dynamically assign an IP address to a client from a DHCP server IP address database on your local network. For TCP/IP-based networks, DHCP reduces the complexity and amount of administrative work involved in reconfiguring computers.

WINS (optional) While DNS is a required component of a foundation network, WINS is optional because, like DNS, it is a naming service. In some cases, you might not need both DNS and WINS, but older operating systems and applications might require WINS. For medium to small networks, WINS is extremely easy to install and manage, and it is not resource-intensive. If you are in doubt about whether you need WINS, you can test your network functionality without it and install it if needed. WINS provides a distributed database for registering and querying dynamic mappings of NetBIOS names for computers and groups used on your network. WINS maps NetBIOS names to IP addresses and was designed to solve the problems arising from NetBIOS name resolution in routed environments. WINS is the best choice for NetBIOS name resolution in routed networks that use NetBIOS over TCP/IP. 6

NetBIOS names are used by earlier versions of Windows operating systems to identify and locate computers and other shared or grouped resources required to register or resolve names for use on the network. NetBIOS names are a requirement for establishing networking services in earlier versions of Windows operating systems. Although the NetBIOS naming protocol can be used with network protocols other than TCP/IP (such as NetBEUI or IPX/SPX), WINS was designed specifically to support NetBIOS over TCP/IP (NetBT). WINS simplifies the management of the NetBIOS namespace in TCP/IP-based networks.

NPS (optional) Network Policy Server (NPS) allows you to centrally configure and manage network policies with the following three features: Remote Authentication Dial-In User Service (RADIUS) server, RADIUS proxy, and Network Access Protection (NAP) policy server. NPS is an optional component of a foundation network, but you should install NPS if any of the following are true: • You are planning to expand your network to include any remote access servers that are compatible with the RADIUS protocol, such as a computer running Windows Server 2008 and Routing and Remote Access service. •

You plan to deploy NAP.

•

You plan to deploy 802.1X wired or wireless access.

TCP/IP TCP/IP in Windows Server 2008 is the following: •

Networking software based on industry-standard networking protocols.

• A routable, enterprise networking protocol that supports the connection of your Windows-based computer to both local area network (LAN) and wide area network (WAN) environments. • Core technologies and utilities for connecting your Windows-based computer with dissimilar systems for the purpose of sharing information. • A foundation for gaining access to global Internet services, such as the World Wide Web and File Transfer Protocol (FTP) servers. •

A robust, scalable, cross-platform, client/server framework.

TCP/IP provides basic TCP/IP utilities that enable Windows-based computers to connect and share information with other Microsoft and non-Microsoft systems, including: •

Windows Vista

•

Windows Server 2003 operating systems

•

Windows XP

•

Internet hosts

•

Apple Macintosh systems 7

•

IBM mainframes

•

UNIX systems

•

Open VMS systems

• Network-ready printers, such as HP LaserJet series printers that use HP JetDirect cards

Foundation Network Overview The following illustration shows the components of a foundation network.

Foundation Network Components Following are the components of a foundation network.

Router This deployment guide provides instructions for deploying a foundation network with two subnets separated by a router that has DHCP forwarding enabled. You can, however, deploy a Layer 2 switch, a Layer 3 switch, or a hub, depending on your requirements and resources. If you deploy a switch, the switch must be capable of DHCP forwarding or you must place a DHCP server on each subnet. If you deploy a hub, you are deploying a single subnet and do not need DHCP forwarding or a second scope on your DHCP server. Static TCP/IP configurations All of the servers in this deployment are configured with static IPv4 addresses. Client computers are configured by default to receive IP address leases from the DHCP server. Global catalog and DNS server Both Active Directory Domain Services (AD DS) and Domain Name System (DNS) are installed on this server, providing directory and name resolution services to all computers and devices on the network. WINS server (optional) Installing Windows Internet Name Service (WINS) on your foundation network is optional. It is often difficult to determine whether applications and services require WINS for name resolution. In some cases, you might need WINS; in other cases, DNS might be the only name resolution service that you need on your network. Because WINS is low maintenance and is not processoruse intensive for medium and small networks, you can install WINS on the DHCP server in the event that applications or services need the service. DHCP server The Dynamic Host Configuration Protocol (DHCP) server is configured with a scope that provides Internet Protocol (IP) address leases to computers on the local subnet. The DHCP server can also be configured with additional scopes to provide IP address leases to computers on other subnets if DHCP forwarding is configured on routers. NPS server (optional) The Network Policy Server (NPS) server is installed as a preparatory step for deploying other network access technologies, such as virtual private network (VPN) servers, wireless access points, and 802.1X authenticating switches. In addition, installing NPS prepares your network for the deployment of Network Access Protection (NAP). Client computers Client computers running Windows Vista® and Windows XP are configured by default as DHCP clients, which obtain IP addresses and DHCP options automatically from the DHCP server.

Foundation Network Planning Before you deploy a foundation network, you must plan the following items. •

Planning subnets 10

•

Planning basic configuration of all servers

•

Planning the deployment of AD-DNS-01

•

Planning domain access

•

Planning the deployment of WINS-01

•

Planning the deployment of DHCP-01

•

Planning the deployment of NPS-01

The following sections provide more detail on each of these items.

Planning subnets In Transmission Control Protocol/Internet Protocol (TCP/IP) networking, routers are used to interconnect the hardware and software used on different physical network segments called subnets. Routers are also used to forward IP packets between each of the subnets. Determine the physical layout of your network, including the number of routers and subnets you need, before proceeding with the instructions in this guide. In addition, to configure the servers on your network with static IP addresses, you must determine the IP address range that you want to use for the subnet where your foundation network servers are located. In this guide, the private IP address range 192.168.1.1 - 192.168.0.254 is used as an example, but you can use any private IP address range. The following recognized private IP address ranges are specified by Internet Request for Comments (RFC) 1918: •

10.0.0.0 – 10.255.255.255

•

172.16.0.0 – 172.31.255.255

•

192.168.0.0 – 192.168.255.255

When you use the private IP address ranges as specified in RFC 1918, you cannot connect directly to the Internet using a private IP address because requests going to or from these addresses are automatically discarded by Internet service provider (ISP) routers. To add Internet connectivity to your foundation network later, you must contract with an ISP to obtain a public IP address. Important When using private IP addresses, you must use some type of proxy or network address translation (NAT) server to convert the private IP address ranges on your local network to a public IP address that can be routed. For more information, see Planning the deployment of DHCP-01.

Planning basic configuration of all servers For each server in the foundation network, you must change the password for the Administrator account on the local computer, rename the computer, and assign and configure a static IP address for the local computer.

11

Planning the Administrator account password For security reasons, it is important to create a password for the Administrator account and to use a strong password. In addition, it is recommended that you use a different Administrator account password for each server on your network. The following is an example of a strong password. Configuration item:

Example value:

Administrator password

Example: J*p2leO4$F Note Strong passwords contain a minimum of 7 characters that consist of each of the following: uppercase letters (A, B, C, lowercase letters (d, e, f), numerals (0, 1, 2, 3), and keyboard symbols (' ~ ! @ # $ % | /).

Planning naming conventions for computers and devices For consistency across your network, it is generally a good idea to use consistent names for servers, printers, and other devices. Computer names can be used to help users and administrators easily identify the purpose and location of the server, printer, or other device. For example, if you have three DNS servers, one in San Francisco, one in Los Angeles, and one in Chicago, you might use the naming convention server function-location-number: • DNS-SF-01. This name represents the DNS server in San Francisco. If additional DNS servers are added in San Francisco, the numeric value in the name can be incremented, as in DNS-SF-02 and DNS-SF-03. •

DNS-LA-01. This name represents the DNS server in Los Angeles.

•

DNS-CH-01. This name represents the DNS server in Chicago.

Choose a naming convention before you install your foundation network using this guide.

Planning static IP addresses Before configuring each computer with a static IP address, you must plan your subnets and IP address ranges. In addition, you must determine the IP addresses of your DNS and WINS servers. If you plan to install a router that provides access to other networks, such as additional subnets or the Internet, you must know the IP address of the router, also called a default gateway, for static IP address configuration. The following table provides example values for static IP address configuration. Configuration items:

Example values:

IP address

192.168.0.3 12

Configuration items:

Example values:

Subnet mask

255.255.255.0

Default gateway

Alternate DNS server

192.168.0.7

Preferred WINS server

192.168.0.2

Alternate WINS server

192.168.0.8

For more information, see Planning the deployment of DHCP-01.

Planning the deployment of AD-DNS-01 Following are key planning steps before installing Active Directory Domain Services (AD DS) and DNS on AD-DNS-01.

Planning the name of the forest root domain A first step in the AD DS design process is to determine how many forests your organization requires. A forest is the top-level AD DS container, and consists of one or more domains that share a common schema and global catalog. An organization can have multiple forests, but for most organizations, a single forest design is the preferred model and the simplest to administer. When you create the first domain controller in your organization, you are creating the first domain (also called the forest root domain) and the first forest. Before you take this action using this guide, however, you must determine the best domain name for your organization. In most cases, the organization name is used as the domain name, and in many cases this domain name is registered. If you are planning to deploy Web servers for your customers or partners, choose a domain name and ensure that the domain name is not already in use.

Planning the forest functional level While installing AD DS, you must choose the forest functional level that you want to use. Domain and forest functionality, introduced in Windows Server 2003 Active Directory, provides a way to enable domain- or forest-wide Active Directory features within your network environment. Different levels of domain functionality and forest functionality are available, depending on your environment. Forest functionality enables features across all the domains in your forest. The following forest functional levels are available: • Windows 2000. This forest functional level supports Windows NT 4.0, Windows 2000, and Windows Server 2003 domain controllers. • Windows Server 2003. This forest functional level supports Windows Server 2003 domain controllers only. 13

• Windows Server 2008. This forest functional level supports Windows Server 2008 domain controllers only. If you are deploying a new domain in a new forest and all of your domain controllers will be running Windows Server 2008, it is recommended that you configure AD DS with the Windows Server 2008 forest functional level during AD DS installation. Important After the forest functional level has been raised, domain controllers running earlier operating systems cannot be introduced into the forest. For example, if you raise the forest functional level to Windows Server 2008, domain controllers running Windows 2000 Server or Windows Server 2003 cannot be added to the forest. Example configuration items for AD DS are provided in the following table. Configuration items:

Example values:

Full DNS name

Examples: •

example.com

•

corp.example.com

Forest functional level:

•

Windows Server 2003

Windows 2000

•

Windows Server 2008

The Windows 2000 forest functional level provides all AD DS features that are available in Windows 2000 Server. If you have domain controllers running later versions of the Windows Server operating system, some advanced features will not be available on those domain controllers while this forest is at the Windows 2000 functional level. Windows Server 2003 The Windows Server 2003 forest functional level provides all features that are available in Windows 2000 forest functional level, and the following additional features: • Linked-value replication, which improves the replication of changes to group memberships. • More efficient generation of complex replication topologies by the Knowledge Consistency Checker (KCC). • Forest trust, which allows organizations to easily share internal 14

Configuration items:

Example values:

resources across multiple forests. Any new domains that are created in this forest will automatically operate at the Windows Server 2003 domain functional level. Windows Server 2008 This forest functional level does not provide any new features over the Windows 2003 forest functional level. However, it ensures that any new domains created in this forest will automatically operate at the Windows Server 2008 domain functional level, which does provide unique features.

Planning DNS zones In DNS, a forward lookup zone is created by default during installation. A forward lookup zone allows computers and devices to query for another computer's or device's IP address based on its DNS name. In addition to a forward lookup zone, it is recommended that you create a DNS reverse lookup zone. With a DNS reverse lookup query, a computer or device can discover the name of another computer or device using its IP address. Deploying a reverse lookup zone typically improves DNS performance and greatly increases the success of DNS queries. When you create a reverse lookup zone, the in-addr.arpa domain, which was defined in the DNS standards and reserved in the Internet DNS namespace to provide a practical and reliable way to perform reverse queries, is installed in DNS. To create the reverse namespace, subdomains within the in-addr.arpa domain are formed, using the reverse ordering of the numbers in the dotted-decimal notation of IP addresses.

15

The in-addr.arpa domain applies to all TCP/IP networks that are based on Internet Protocol version 4 (IPv4) addressing. The New Zone Wizard automatically assumes that you are using this domain when you create a new reverse lookup zone. While you are running the New Zone Wizard, the following selections are recommended: Configuration Items

Network ID = 192.168.0.

Dynamic Updates

Allow only secure dynamic updates

Planning domain access To log onto the domain, the computer must be a domain member computer and the user account must be created in AD DS before the logon attempt. Note You cannot log on to the domain with a user account that is located in the Security Accounts Manager (SAM) user accounts database on the local computer. After the first successful logon with domain logon credentials, the logon settings persist unless the computer is removed from the domain or the logon settings are manually changed. Before you log on to the domain: • Create user accounts in AD DS. Each user must have an Active Directory Domain Services user account in Active Directory Users and Computers. For more information, see Create a User Account in Active Directory Users and Computers. • Ensure IP address configuration. To join a computer to the domain, the computer must have an IP address. In this guide, servers are configured with static IP addresses and client computers receive IP address leases from the DHCP server. For this reason, the DHCP server must be deployed before you join clients to the domain. Fore more information, see Install Dynamic Host Configuration Protocol (DHCP). • Join the computer to the domain. Any computer that provides or accesses network resources must be joined to the domain. For more information, see Join the Computer to the Domain.

16

Planning the deployment of WINS-01 If you determine that you need to deploy WINS as well as DNS on your network, you must plan how many WINS servers to deploy. • On smaller networks, a single WINS server can adequately service up to 10,000 clients for NetBIOS name resolution requests. To provide additional fault tolerance, you can configure a second computer running Windows Server® 2008 as a secondary, or backup, WINS server for clients. If you use only two WINS servers, you can easily configure them as replication partners. For simple replication between two servers, one server should be set as a pull partner and the other as a push partner. Replication can be either manual or automatic. • Large networks sometimes require more WINS servers for several reasons including, most importantly, the number of client connections per server. The number of users that each WINS server can support varies with usage patterns, data storage, and the processing capabilities of the WINS server computer. When planning your servers, remember that each WINS server can simultaneously handle hundreds of registrations and queries per second.

Planning the deployment of DHCP-01 Following are key planning steps before installing the DHCP server role on DHCP-01.

Planning DHCP servers and DHCP forwarding Because DHCP messages are broadcast messages, they are not forwarded between subnets by routers. If you have multiple subnets and want to provide DHCP service for each subnet, you must do one of the following: •

Install a DHCP server on each subnet

• Configure routers to forward DHCP broadcast messages across subnets and configure multiple scopes on the DHCP server, one scope per subnet. In most cases, configuring routers to forward DHCP broadcast messages is more cost effective than deploying a DHCP server on each physical segment of the network.

Planning IP address ranges Each subnet must have its own unique IP address range. These ranges are represented on a DHCP server with scopes. A scope is an administrative grouping of IP addresses for computers on a subnet that use the DHCP service. The administrator first creates a scope for each physical subnet and then uses the scope to define the parameters used by clients. A scope has the following properties: • A range of IP addresses from which to include or exclude addresses used for DHCP service lease offerings. •

A subnet mask, which determines the subnet for a given IP address. 17

•

A scope name assigned when it is created.

• Lease duration values, which are assigned to DHCP clients that receive dynamically allocated IP addresses. • Any DHCP scope options configured for assignment to DHCP clients, such as DNS server IP address, router/default gateway IP address, and WINS server IP address. • Reservations are optionally used to ensure that a DHCP client always receives the same IP address. Before deploying your servers, list your subnets and the IP address range you want to use for each subnet.

Planning subnet masks Network IDs and host IDs within an IP address are distinguished by using a subnet mask. Each subnet mask is a 32-bit number that uses consecutive bit groups of all ones (1) to identify the network ID and all zeroes (0) to identify the host ID portions of an IP address. For example, the subnet mask normally used with the IP address 131.107.16.200 is the following 32-bit binary number: 11111111 11111111 00000000 00000000

This subnet mask number is 16 one-bits followed by 16 zero-bits, indicating that the network ID and host ID sections of this IP address are both 16 bits in length. Normally, this subnet mask is displayed in dotted decimal notation as 255.255.0.0. The following table displays subnet masks for the Internet address classes. Address class

Bits for subnet mask

Subnet mask

Class A

11111111 00000000 00000000 00000000

255.0.0.0

Class B

11111111 11111111 00000000 00000000

255.255.0.0

Class C

11111111 11111111 11111111 00000000

255.255.255.0

When you create a scope in DHCP and you enter the IP address range for the scope, DHCP provides these default subnet mask values. Typically, default subnet mask values (as shown in the preceding table) are acceptable for most networks with no special requirements and where each IP network segment corresponds to a single physical network. In some cases, you can use customized subnet masks to implement IP subnetting. With IP subnetting, you can subdivide the default host ID portion of an IP address to specify subnets, which are subdivisions of the original class-based network ID. By customizing the subnet mask length, you can reduce the number of bits that are used for the actual host ID. 18

To prevent addressing and routing problems, you should make sure that all TCP/IP computers on a network segment use the same subnet mask and that each computer or device has an unique IP address.

Planning exclusion ranges You can exclude IP addresses from distribution by the DHCP server by creating an exclusion range for each scope. You should use exclusions for all devices that are configured with a static IP address. The excluded addresses should include all IP addresses that you assigned manually to other servers, non-DHCP clients, diskless workstations, or Routing and Remote Access and PPP clients. It is recommended that you configure your exclusion range with extra addresses to accommodate future network growth. The following table provides an example exclusion range for a scope with an IP address range of 192.168.0.1 - 192.168.0.254. Configuration items:

Example values:

Exclusion range Start IP Address

192.168.0.1

Exclusion range End IP Address

192.168.0.15

Planning TCP/IP static configuration Certain devices, such as routers, DHCP servers, and DNS servers, must be configured with a static IP address. In addition, you might have additional devices, such as printers, that you want to ensure always have the same IP address. List the devices that you want to configure statically for each subnet, and then plan the exclusion range you want to use on the DHCP server to ensure that the DHCP server does not lease the IP address of a statically configured device. An exclusion range is a limited sequence of IP addresses within a scope, excluded from DHCP service offerings. Exclusion ranges assure that any addresses in these ranges are not offered by the server to DHCP clients on your network. For example, if the IP address range for a subnet is 192.168.0.1 through 192.168.0.254 and you have ten devices that you want to configure with a static IP address, you can create an exclusion range for the 192.168.0.x scope that includes ten or more IP addresses: 192.168.0.1 through 192.168.0.15. In this example, you use ten of the excluded IP addresses to configure servers and other devices with static IP addresses and five additional IP addresses are left available for static configuration of new devices that you might want to add in the future. With this exclusion range, the DHCP server is left with an address pool of 192.168.0.16 through 192.168.0.254.

Planning the deployment of NPS-01 If you intend to deploy network access servers, such as wireless access points or VPN servers, after deploying your foundation network, it is recommended that you deploy NPS. When you use NPS as a Remote Authentication Dial-In User Service (RADIUS) server, NPS performs authentication and authorization for connection requests through your network access servers. NPS also allows you to centrally configure and manage network policies that determine who can access the network, how they can access the network, and when they can access the network. Following are key planning steps before installing NPS. • Plan the user accounts database. By default, if you join the server running NPS to an Active Directory domain, NPS performs authentication and authorization using the AD DS user accounts database. In some cases, such as with large networks that use NPS as a RADIUS proxy to forward connection requests to other RADIUS servers, you might want to install NPS on a non-domain member computer.

20

• Plan the use of Network Access Protection (NAP). With some NAP enforcement methods, it is required that you install NPS on a specific server. For example, if you deploy NAP with DHCP, NPS must be installed on the DHCP server. • Plan RADIUS accounting. NPS allows you to log accounting data to a SQL Server database or to a text file on the local computer. If you want to use SQL Server logging, plan the installation and configuration of your server running SQL Server.

Foundation Network Deployment To deploy a foundation network, the basic steps are as follows: 1. Configuring All Servers 2. Deploying AD-DNS-01 3. Joining Computers to the Domain and Logging On 4. Deploying WINS-01 (optional) 5. Deploying DHCP-01 6. Deploying NPS-01 (optional) Note The procedures in this guide do not include instructions for those cases in which the User Account Control dialog box opens to request your permission to continue. If this dialog box opens while you are performing the procedures in this guide, and if the dialog box was opened in response to your actions, click Continue.

•

Install AD DS and DNS for a New Forest

•

Create a User Account in Active Directory Users and Computers

•

Add a Group

•

Assign Group Membership

•

Configure a DNS Reverse Lookup Zone

Administrative privileges If you are installing a small network and are the only administrator for the network, it is recommended that you create a user account for yourself, and then add your user account as a member of both Enterprise Admins and Domain Admins. Doing so will make it easier for you to act as the administrator for all network resources. It is also recommended that you log on with this

26

account only when you need to perform administrative tasks, and that you create a separate user account for performing non-IT related tasks. If you have a larger organization with multiple administrators, refer to AD DS documentation to determine the best group membership for organization employees. Domain user accounts vs. user accounts on the local computer One of the advantages of a domain-based infrastructure is that you do not need to create user accounts on each computer in the domain. This is true whether the computer is a client computer or a server. Because of this, you should not create user accounts on each computer in the domain. Create all user accounts in Active Directory Users and Computers and use the preceding procedures to assign group membership. By default, all user accounts are members of the Domain Users group. After you have joined a computer to the domain, members of the Domain Users group can log on to any domain member client computer. Note Members of the Domain Users group cannot log on to computers running Windows Server® 2008. You can configure user accounts to designate the days and times that the user is allowed to log on to the computer. You can also designate which computers each user is allowed to use. To configure these settings, open Active Directory Users and Computers, locate the user account that you want to configure, and double-click the account. In the user account Properties, click the Account tab, and then click either Logon Hours or Log On To.

Create a New DHCP Scope

Install Dynamic Host Configuration Protocol (DHCP) You can use this procedure to install and configure the DHCP Server role using the Add Roles Wizard. Membership in Domain Admins, or equivalent, is the minimum required to perform this procedure. To install DHCP 1. Do one of the following: a. In Initial Configuration Tasks, in Customize This Server, click Add roles. The Add Roles Wizard opens. b. Click Start, and then click Server Manager. In the left pane of Server Manager, click Roles, and in the details pane, in Roles Summary, click Add Roles. The Add Roles Wizard opens. 2. In Before You Begin, click Next. Note The Before You Begin page of the Add Roles Wizard is not displayed if you have previously selected Do not show this page again when the Add Roles Wizard was run. 3. In Select Server Roles, in Roles, select DHCP Server, and then click Next. 37

4. In DHCP Server, click Next. 5. In Select Network Connection Bindings, in Network Connections, select the IP addresses that are connected to the subnets for which you want to provide DHCP service, and then click Next. 6. In Specify IPv4 DNS Server Settings, in Parent Domain, verify that the name of the DNS domain that clients use for name resolution is correct. For example, if your domain is named example.com, verify that the DNS domain name is example.com. 7. In Preferred DNS server IPv4 address, type the IPv4 address of your preferred DNS server, and then click Validate. In Alternate DNS server IPv4 Address, type the IPv4 address of your alternate DNS server, if any, and then click Validate. Note If a DNS server responds when you click Validate, the DHCP installation wizard indicates the specified address for the DNS server is valid. If no DNS server responds when you click Validate, the DHCP installation wizard returns the message: The DNS server at the specified IP address is not responding. 8. Click Next. In Specify IPv4 WINS Server Settings, select one of the following: • If you do not have WINS servers on your network, select WINS is not required for applications on this network. • If one or more WINS servers are deployed on your network, select WINS is required for applications on this network. In Preferred WINS server IP address, type the IPv4 address of your preferred WINS server. In Alternate WINS server IP Address, type the IPv4 address of your alternate WINS server, if any, and then click Next. 9. In Add or Edit DHCP Scopes, click Add. The Add Scope dialog box opens. 10. In the Add Scope dialog box, type values for all required items, and in Subnet Type, select either Wired or Wireless, depending on the IP address lease duration that you prefer, and then do one of the following: • To automatically activate the scope immediately after DHCP installation is complete, click Activate this scope. If there are computers or devices on the network that have static IP addresses, do not activate the scope until after you have created an exclusion range. The exclusion range prevents the DHCP server from leasing IP addresses that are already in use by a statically configured device. • To manually activate the scope later, use the DHCP Microsoft Management Console (MMC). 11. Click OK. This returns you to the Add or Edit DHCP Scopes page. If your network has multiple subnets that are serviced by this DHCP server, add scopes for each subnet using steps 9 and 10. Click Next. 12. In Configure DHCPv6 Stateless Mode, select whether you want to configure 38

the DHCP server for DHCPv6 stateless operation, and then click Next. 13.
