After tranfering the first 4 operation master roles without a problem from windows 2003 to the new windows 2008 server, the Schema Master role gave an error using the Active Directory Schema mmc add-in:
The parameter is incorrect.
The transfer of the current Operation Master could not be preformed.
Solution: First check if the windows 2003 role owner is alive and you can reach that server. You can check which server holds the role “netdom query fsmo”. If that all is fine try moving the role with ntdsutil.
Open a command prompt on your windows 2008 server and type: ntdsutil
Type roles and then press ENTER
Type connections, ENTER
Type connect to server
Type q, ENTER
Type Transfer schema master, ENTER
You will get a warning message choose Yes to continue.
Then type q and again q to exit ntdsutil.
You can use: Transfer domain naming master, Transfer infrastructure master, Transfer PDC and Transfer RID master if you also would transfer the other FSMO roles with ntdsutil.
