BE2010R3SP3 - Remote Agent Install validation fails with Error connecting to the remote server. Ensure the server is available, has WMI enabled, and is not blocked by a firewall. 1603."
I'm sure it used to work because my list (under Tools > Install Agents and Media Servers on Other Servers) contains a list of servers I'm currently backing up; however, now all current existing servers in list and newly added servers displays the error:
Error connecting to the remote server. Ensure the server is available, has WMI enabled, and is not blocked by a firewall. 1603.
I think this is related to my Media server. Backups are still fine. Checking in Event Viewer shows:
DCOM was unable to communicate with the computer using any of the configured protocols.
Checking in Symantec's push logs shows:
The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)
DNS resolution works fine. I get the same error using IP addresses. Firewall is disabled on both machines. I've even tried telnetting to port 135 from the media server and that connects fine.
Any suggestions? I would really prefer to not install locally as that would mean I won't be able to update my agents through the Media Server.
