The Active Directory Domain Controller that was holding FSMO or Flexible Single Master of Operations responsibilities has failed.
I’m confident that any System Administrator you speak with has visited this location at some point throughout their career. A domain controller has failed and can not be repaired. We have a backup domain controller or have created a new one, but now we need to transfer the FSMO responsibilities. This is how it is done:
To begin, log in to the new possible FSMO role holder Domain controller and enter each of the following commands:
Where ‘MyDomainController’ is the name of your server, type the following:
connect to server MyDomainController
After that, press q. (Yes, it seems odd to quit, but this is normal)
Now is the time to seize and play the role of your choosing:
seize schema master
When prompted with the question ‘Are you certain you want server “MyDomainController” to seize the role with the value below’, click Yes.
Press q once more:
The role has been taken.
