Migrating ICS Clients

ICS clients are already configured to obtain an IP address automatically, so in theory, they require no reconfiguration beyond a simple reboot if you want to migrate to DHCP. However, you might find that in practice, ICS clients stubbornly cling to their ICS addresses even after DHCP is deployed. To prevent such complications, you can first apply a manual (static) address to the client computers after the ICS connection is deleted; this procedure breaks the ICS connection. Then restart the client computers. After the clients restart, they will migrate cleanly to DHCP as soon as you reconfigure them to obtain an address automatically.

Verifying the Configuration

After you configure your DHCP server, and after you have authorized the server and activated the scope, you need to verify that the service is working on your client computers. Restart your DHCP client computers (or use Ipconfig /renew) and then enter the ipconfig /all command at the command prompt. With the /all switch, the Ipconfig command displays all of the parameters you have configured for the lease, including DHCP options.

Tip You can assign users to the domain local security group DHCP Users if you want to allow them to read DHCP information without being able to manage or modify this data.
