Seizing FSMO Roles

Tuesday, May 27th, 2008

This is not something that recently happened, but I do feel compelled to share this tale. Long before I was in charge of our Domain, we had an outside company set things up. We had a Windows 2000 Mixed Mode Domain with 2 domain controllers. It is a fairly simple setup. Well, some time last year we purchased the CALs for Windows 2003 and 2 new servers to replace our aging 2000 server domain controllers.

During the process, I intended to replace one server at a time, I had a plan all laid out. I first wrote my login script to replace the Static DNS entry for the first DC on all the computers in the domain with the new DC replacing it. I then transfered the FSMOs on the first DC to the second DC. I then ran ADPREP and then I hit a snag! Basically, the error kept telling me the following:

The schema master did not complete a replication cycle after the last reboot. The schema master must complete at least one replication cycle before the schema can be extended.
[User Action]
Verify that the schema master is connected to the network and can communicate with other domain controllers. Use the Sites and Services snap-in to replicate between the schema operations master and at least one replication partner. After replication has succeeded, run adprep again.
