About this tag
The rpcserverunavailable error often appears in Windows Server environments when Active Directory domain controllers cannot communicate over RPC. In one case, after transferring FSMO roles from a Windows Server 2012 R2 domain controller to a new Windows Server 2019 domain controller, the error occurred when the old DC was disconnected.

Troubleshooting typically involves checking network connectivity, firewall rules, DNS resolution, and RPC service status on the affected servers.
