We recently had a domain controller die that held the Schema Master role.

I've tried to get it back from a backup without any joy.  When I try to sieze the role I get the following error.

ntdsutil
ntdsutil: roles
fsmo maintenance: connections
server connections: connect to server dc1
Binding to dc1 ...
Connected to dc1 using credentials of locally logged on user.
server connections: q
fsmo maintenance: seize schema master
Attempting safe transfer of schema FSMO before seizure.

I'm running the commands on a Windows 2008 R2 server


Any suggestions?

Ah I notice the error is when it did it the gracefull way, then it forced it.

I'll check tomorrow to see it it lists itself as the owner.

Thanks

Thanks.  

A quick check of the FSMO role owners confirms it did work and the message was just to say it was not gracefully taken.
