Installing DHCP components

Installing DHCP components

On a server running Windows Server 2012 R2, follow these steps to enable the server to function as a DHCP server:

1. DHCP servers should be assigned a static IPv4 and IPv6 address on each subnet to which they are connected and will service. Be sure that the server has static IPv4 and IPv6 addresses.

2. In Server Manager, tap or click Manage, and then tap or click Add Roles And Features, or select Add Roles And Features in the Quick Start pane. This starts the Add Roles And Features Wizard. If the wizard displays the Before You Begin page, read the Welcome text, and then tap or click Next.

3. On the Installation Type page, Role-Based Or Feature-Based Installation is selected by default. Tap or click Next.

4. On the Server Selection page, you can choose to install roles and features on running servers or virtual hard disks. Either select a server from the server pool or select a server from the server pool on which to mount a virtual hard disk (VHD). If you are adding roles and features to a VHD, tap or click Browse, and then use the Browse For Virtual Hard Disks dialog box to locate the VHD. When you are ready to continue, tap or click Next.

NOTE Only servers running Windows Server 2012 R2 and that have been added for management in Server Manager are listed.

5. On the Select Roles page, select DHCP Server. If additional features are required to install a role, you’ll get an additional dialog box. Tap or click Add Features to close the dialog box and add the required features to the server installation. When you are ready to continue, tap or click Next three times.

6. If the server on which you want to install the DHCP Server role doesn’t have all the required binary source files, the server gets the files via Windows Update by default or from a location specified in Group Policy.

NOTE You also can specify an alternate path for the required source files. To do this, click the Specify An Alternate Source Path link, enter that alternate path in the box provided, and then tap or click OK. For network shares, enter the UNC path to the share, such as CorpServer82WinServer2012. For mounted Windows images, enter the Windows Imaging (WIM) path prefixed with WIM: and including the index of the image to use, such as WIM: CorpServer82WinServer2012install.wim:4.

7. After you review the installation options and save them as necessary, tap or click Install to begin the installation process. The Installation Progress page tracks the progress of the installation. If you close the wizard, tap or click the Notifications icon in Server Manager, and then tap or click the link provided to reopen the wizard.

8. When Setup finishes installing the DHCP Server role, the Installation Progress page will be updated to reflect this. Review the installation details to ensure that all phases of the installation were completed successfully.

9. As stated in the Post-Deployment Configuration task panel, additional configuration is required for the DHCP server. Tap or click the Complete DHCP Configuration link to start the DHCP Post-Install Configuration Wizard.

10. The Description page states that the DHCP Administrators and DHCP Users groups will be created in the domain for delegation of DHCP Server administration. Additionally, if the DHCP server is joined to a domain, the server will be authorized in Active Directory. Tap or click Next.

11. On the Authorization page, do one of the following to specify the credentials to use to authorize the DHCP server in Active Directory:

? Your current user name is shown in the User Name text box. If you have administrator privileges in the domain that the DHCP server is a member of and you want to use your current credentials, tap or click Commit to attempt to authorize the server by using these credentials.

? If you want to use alternate credentials or if you are unable to authorize the server by using your current credentials, select Use Alternate Credentials, and then tap or click Specify. In the Windows Security dialog box, enter the user name and password for the authorized account, and then tap or click OK. Tap or click Commit to attempt to authorize the server by using these credentials.

? If you want to authorize the DHCP server later, select Skip AD Authorization, and then tap or click Commit. Keep in mind that in domains, only authorized DHCP servers can provide dynamic IP addresses to clients.

12. When the wizard finishes the post-install configuration, review the installation details to ensure that tasks were completed successfully, and then tap or click Close.

13. Next, you need to restart the DHCP Server service on the DHCP server so that the DHCP Administrators and DHCP Users groups can be used. To do this, tap or click DHCP in the left pane of Server Manager. Next, in the main pane, on the Servers panel, select the DHCP server. Finally, on the Services panel, press and hold or right-click the entry for the DHCP Server, and then tap or click Restart Service.

14. To complete the installation, you need to do the following:

? If the server has multiple network cards, review the server bindings and specify the connections that the DHCP server supports for servicing clients. See “Configuring server bindings” later in this chapter.

? Configure server options to assign common configuration settings for DHCPv4 and DHCPv6 clients, including 003 Router, 006 DNS Servers, 015 DNS Domain Name, and 044 WINS/NBNS Servers. See “Setting scope options” later in the chapter.

? Create and activate any DHCP scopes that the server will use, as discussed in “Creating and managing scopes” later in the chapter.
