windows service command RPC error (sc.exe or psservice)

Question

I am getting the following error when i try to run the command from remote machine C:>sc \machinename query [SC] OpenSCManager FAILED 1722:

The RPC server is unavailable.

• I have admin previlages to that machine.

Any solution let me know.

Answer 1

Did you add the exception to the firewall?

Answer 2

The error 1722 is : The RPC server is unavailable. Verify if RPC service (Remote Procedure Call (RPC)) is running at remote machine with telnet, try at command line:
*>telnet your.server 135

If no errors occurs the RPC server is probably ok, than check system events for issues.
