File restores to original location fail with communications error RRS feed

  • Question

  • I am attempting to do some test restores from DPM 2012 SP1.  I have multiple servers and guest VM's protected both as servers and as VM's.  When I try to restore a single file to the original location on the file server (Windows 2008 Guest OS), the restore fails with the following error:

    Affected area: D:\
    Occurred since: 11/11/2013 2:47:15 PM
    Description: The recovery jobs for Volume D:\ that started at Monday, November 11, 2013 2:40:08 PM, with the destination of fileserver.internal.com, have completed. Most or all jobs failed to recover the requested data. (ID 3111)
     DPM failed to communicate with DPM.internal.com because the computer is unreachable. (ID 41 Details: No such host is known (0x80072AF9))
     More information
    Recommended action: 1) Make sure that DPM.internal.com is online and remotely accessible from the DPM server.
    2) If a firewall is enabled on DPM.internal.com, make sure that it is not blocking requests from the DPM server.
    3) If you are using backup LAN, make sure that the backup LAN settings are valid.
     On the Jobs tab in the Monitoring tasks area, group jobs by type to view details of the recovery jobs.
     Retry the recovery job...

    Note that the communicatons failure is with the DPM server itself!  A restore to an alternative location on the DPM server succeeds very quickly, but trying to restore to the file server fails.  Here is information on the environment:

    DPM: Windows 2012 Guest VM running on Windows 2012 Host.  It has a static IPv4 address for both the data and backup VLANs.  The Windows firewall is disabled.

    File Server: Windows 2008 (R1) Guest VM running on Windows 2008 host.  It has a static IPv4 address for the data VLAN only.  It is running McAfee AV with an exclusion for the DPM directories.  The Windows Firewall is disabled.

    I can ping back and forth between the two servers, and I've run the RPC and Webcon tests with no errors.  Can anyone tell me what I can look at next?

    Thanks,
    Joe
