Problem:
Your Active Directory Domain Controller has failed and it held FSMO or Flexible Single Master of Operations roles.
Solution:
I’m certain that any System Administrator you ask will have been here at some point in their career. A Domain Controller has failed and is beyond repair, we have a backup domain controller or built a new one but now need to transfer the FSMO roles over. This is how you do it:
First login to the new potential FSMO role holder Domain controller and type each of the following commands followed by pressing enter:
Type:
ntdsutil
Type:
roles
Type:
connections
Type the below where ‘MyDomainController’ is the name of your server:
connect to server MyDomainController
Then press q (Yes seems odd to quit but this is normal)
q
Now you need to seize and the role of your choice:
seize schema master naming master pdc rid master infrastructure master
When asked ‘Are you sure you want server “MyDomainController” to seize the <Role name> with the value below’ click yes.
Press q again:
q
The role is seized.
