DPM 2012 R2 backup of Workgroup computer error RRS feed

  • Question

  • Hi, we have a Workgroup server that we had successfully backed up to a DPM 2012 Server.

    Since then we have built 2 brand new DPM 2012 R2 servers.

    I have uninstalled the DPM 2012 agent from the Workgroup computer and have installed the new DPM 2012 R2 agent successfully.

    However, when i try to Attach the agent I am getting 'Unable to contact the protection agent on server' errors.

    I have run the Set-DPMServer -IsNonDomainServer command correctly so the Firewall rules are there ( I have also turned the FW off to test but same error results). I am using the same account details created via Set-DPMserver to attach the agent on the DPM server.

    The Event Logs on the DPM 2012 R2 server show DCOM errors (Event 10028, DCOM was unable to communicate with the computer using any of the configured protocols; requested by PID      5e4 (C:\Program Files\Microsoft System Center 2012 R2\DPM\DPM\bin\msdpm.exe).)

    I have even uninstalled the 2012 R2 agent and re-installed the 2012 agent and that attaches fine, no problem.

    Can anyone help/advise?

    David
