DHCP Server Migration: Verifying the Migration
Updated: April 29, 2009
Applies To: Windows Server 2008 R2
When all the migration steps are complete, you can use the following procedure to verify that the DHCP server role migration was successful. If the migration failed, you can return to the previous valid configuration by following the steps in DHCP Server Migration: Post-Migration Tasks.
Follow these steps to confirm that the DHCP destination server is now serving the domain.
Membership in Domain Administrators, or equivalent, is the minimum required to complete this procedure. Review details about how to use the appropriate accounts and group memberships at Understanding Groups: Default groups (http://go.microsoft.com/fwlink/?LinkId=83477).
Make sure that the destination server is authorized by running the following command in a Windows PowerShell window:
netsh DHCP show server
The output of this command must contain the name of the DHCP destination server.
Check whether DHCP server is running on the destination server. In Task Manager, on the Services tab, the DHCP server status should be Started. You also use Task Manager to confirm that the status of the source server is Stopped.
Verify that the client computers are correctly receiving IP addresses on request by running the following commands at a command prompt on a client computer:
If the IP address of the DHCP server has not changed, you do not have to run the ipconfig /release command. Running ipconfig /renew should be sufficient.
The output of these commands should show that the client computer was issued an IP address.
Use the DHCP console to verify that the scopes and other settings were migrated. To connect to the destination server, click Action, click Add Server, and then type the IP address or host name of the DHCP server. In the console tree, expand the server node, and then expand the IPv4 and IPv6 nodes to confirm that the scopes have been migrated. Then locate the folders for the scopes and view the address range, reservations, scope options, and active leases to verify the same. You can also go to the Server Options folder and verify the migrated server options.
