server disconnection
About this tag
The tag 'server disconnection' covers issues that arise when a domain controller is removed from the network. In one example, after promoting a Windows Server 2019 domain controller and transferring FSMO roles from a Windows Server 2012 R2 DC, disconnecting the old DC causes Active Directory to stop functioning. Commands like 'netdom query fsmo' fail with 'The RPC server is unavailable.' This tag is relevant for Windows Server administrators troubleshooting AD replication, FSMO role transfers, and connectivity problems after a server is disconnected.
