Section C: Migrate custom settings to the Management Server

Updated: March 10, 2009

Follow these steps to apply the custom settings that your existing DHCP Server service is using to the Windows EBS Management Server.

To apply custom settings to the Management Server
  1. Write down the custom settings that your existing DHCP Server service is using. This includes reservations, scope options, and server options.

    For instructions about how to find these settings, see the "Do you have custom settings on your existing DHCP server?" section in How to Answer Questions in the Decision Flowchart later in this document.

  2. Deactivate your existing DHCP server scopes. For example, if your existing DHCP server is running Windows Server 2003 or Windows Server 2008:

    1. Open the DHCP console: Click Start, click Administrative Tools, and then click DHCP.

    2. Right-click each Scope in the left pane and click Deactivate.

  3. Disable your existing DHCP server so that it no longer serves addresses. (This is important because network issues will occur if multiple DHCP servers give out IP addresses in the same range to computers on your network.)

    1. Click Start, click Administrative Tools, and then click Services.

    2. Right-click DHCP Server, and then click Properties.

    3. On the General tab, in the Startup type list box, click Disabled. Then click OK.

    4. Right-click DHCP Server, and then click Stop.

  4. Log on to the Management Server as domain administrator.

  5. To open the DHCP console, click Start, click Administrative Tools, and then click DHCP.

  6. In the left pane, expand the node for the Management Server and click IPv4.

  7. If an error message appears in the right pane that says: Cannot find the DHCP server, start the DHCP Server service as follows:

    1. Click Start, click Administrative Tools, and then click Services.

    2. Right-click DHCP Server, and then click Start.

    3. Right-click DHCP Server, and then click Properties.

    4. On the General tab, in the Startup type list box, click Automatic. Then click OK.

  8. In the DHCP console, click Scope. (If you just started the DHCP Server service, you might need to refresh the console.) Apply the settings that you wrote down in step 1 to the Management Server as follows:

    1. If your DHCP server had reservations (IP addresses that some computers always receive), click Reservations in the left pane and recreate the reservations.

    2. If your DHCP server had scope options (such as specifying an IRC server or NNTP server), click Scope Options in the left pane and recreate the options. Be careful not to overwrite the Windows EBS settings for DNS Servers, Domain name, and Router.

    3. If your DHCP server had server options (options that apply to all scopes), click Server Options in the left pane and recreate the options. Be careful not to specify settings for DNS Servers, Domain name, and Router.
