Today I had to move the fsmo-roles, and phase out an old DC.
These days you can powershell it.
Since you are working with Active Directory, log in as an admin user, fire up powershell and a do a:
Get the roles with:
Get-ADDomain | Select-Object InfrastructureMaster,PDCEmulator,RIDMaster | Format-List
Get-ADForest | Select-Object DomainNamingMaster,SchemaMaster | Format-List
Move the roles with:
Move-ADDirectoryServerOperationMasterRole -OperationMasterRole DomainNamingMaster,PDCEmulator,RIDMaster,SchemaMaster,InfrastructureMaster -Identity DC01
Then get the roles again to see if they moved.
It’s not everyday I have to do this, so I had to look it up myself.
The three mega-important commands displayed here for my and perhaps your convience.
You may sometimes even forget these roles exist, but without them, the domain would break.
Hope this helps you,
