I have (2) Windows 2000 servers and am trying to retire Server 1. Created a Windows 2008 R2 Core host and a Windows 2008 R2 guest called Server 3. Upgraded the AD and made Server 3 a DC with all of the FSMO roles. Applied Windows updates to Server 3 and it will not come back up. Had not setup backup or taken a snapshot yet. Tried a Startrep that is stuck. So I need to remove Server 3 from the AD and rebuild or replace it. I could build a Server 4 in a virtual environment. I have researched 2 possible approaches. 1). Sieze the roles and move them to Server 1. Remove Server 3. Clean up the metadata. Rebuild Server 3 with the same name and repromote to a DC. or 2) Create Server 4 and promote it to DC. Sieze and move the roles to Server 4. Then remove Server 3 and clean up metadata.
Has anyone done this? Which would be the better way to handle the situation? What gotshas are likely?
