should be you Firewall 

Hello Michael,

It still shows the same error :

"The RPC server is unavailable (0x800706BA)

If you recently installed a protection agent on dhnl009as004.intra.local, the computer may be restarting. Wait a few minutes after restarting the computer for the protection agent to become available. If the problem persists, do the following:
1) Verify that dhnl009as004.intra.local is remotely accessible from the DPM server.
2) If a firewall is enabled on dhnl009as004.intra.local, verify that it is not blocking requests from the DPM server. 
3) If dhnl009as004.intra.local is a workgroup server the password for the DPM user accounts may have changed or expired. To resolve this error, run SetDpmServer with the -UpdatePassword flag on the protected computer and Update-NonDomainServerInfo.ps1 on the DPM server.
4) Restart the DPM Protection Agent service on dhnl009as004.intra.local. If the service fails to start, uninstall the protection agent by using Add or Remove Programs in Control Panel on dhnl009as004.intra.local. Then in the Management task area, on the Agents tab, in the Actions pane, click Install to reinstall the protection agent on dhnl009as004.intra.local "

I have tried all the four measures. Does not help.

Thanks and Regards,
