The RPC server is unavailable

Question

Hi all!

My backup fails with the above mentioned error. (HRESULT: 0x800706BA)

I've tried to connect to this server with wbemtest, but I got the same error like in Veeam.
The target server has been already restarted. The firewall on both machines are turned off completely. RPC services & Remote Registry have been restarted, and running at the time of connect.

Do you what should I try next?

Answer 2

Hi RevKrisz-2788,

It's an Firewall Issue, although as you said The firewall on both machines are turned off completely.

Turning it Off won't open the port it closes when it was enabled.

Please Try the Test-NetConnection cmdlet to check if the port 135 is open.
(Alternatively, you can use the telnet client)

Test-NetConnection -ComputerName MyComputer -Port 135

Because port 135 need to be open to get it work perfectly.

You can also check after opening port 135 that Windows Management Instrumentation service is running or not on the remote computer set it to auto start and all RPC to auto start after restart.
