I am trying to decommission a DC and have been following the steps required\nfrom Technet but have crossed a stumbling block. It will not allow me to\ntransfer the Domain Naming Master or the Schema Master to the proposed new DC.\n\nI have tried this two ways:\n1. Via Operations Manager\n2. Via dcpromo to decommission the current DC\n\nBy using the operations manager i get the following message:\n"The transfer of the operations master role cannot be performed because:\nThe requested FSMO operation failed. The current FSMO holder could not be\ncontacted" (Even though the current FSMO holder is the server I am running\nthe Op Manager from)\n\nBy using the dcpromo i get the following message:\n"The directory service was unable to transfer ownership of one or more\nfloating single-master roles to the other servers"\n\nAll tests (netdiag /test:dns) pass successfully as does verifying\ncommunication with other DC and Verify the existance of operations masters.\n\nWhat am i missing?
