In some special cases, as shown below, we cannot trasfer the Operations Master (FSMO) roles from one Domain Controller to another Domain Controller .
• A Domain Controller that currently owns an Operations Master (FSMO) role is demoted forcefully by using the dcpromo /forceremoval command.
• The Operations Master role holder is experiencing an operational error that prevents an FSMO-dependent operation from completing successfully and that role cannot be transferred.
• The operating system on the computer that originally owned a specific Operations Master (FSMO) role no longer exists.
The Ntdsutil tool allows you to transfer and seize operations master roles. When you use the Ntdsutil command-line tool to seize an operations master role, the tool attempts a transfer from the current role owner first. Then, if the existing operations master is unavailable, it performs the seizure.
