Error communicating with manually installed protection agent on client RRS feed

  • Question

  • I have a client that I couldn't install the agent on from the DPM Administrator Console (I'm using 2012 R2)

    To install I did the following:
    Pushd to the directory for the latest agent on the DPM server
    Ran DPMAgentInstaller_amd64.exe <DPM server name>
    Rebooted the protected machine.
    C:\Program Files\Microsoft Data Protection Manager\DPM\bin\SetDpmServer.exe - dpmServerName <DPM server name>

    This came back OK saying it had added the firewall rules although the Windows firewall was disabled on the workstation anyway.

    On the DPM server:

    Install Agent
    Attach Agents> Computer on trusted domain
    Selected client.

    This finished successfully.

    The agent Status in the Management> Agents screen is listed as Error (see below for details). The machines are in the same domain and there are no firewalls in the way. I've been careful to set it up as per the instructions, what may I be missing here?


    Protection agent version:    4.2.1235.0
    Error:    Data Protection Manager Error ID: 270
        The agent operation failed on <protected client FQDN> because DPM could not communicate with the DPM protection agent. The computer may be protected by another DPM server, or the protection agent may have been uninstalled on the protected computer.
    If <protected client FQDN> is a workgroup server, the password for the DPM user account could have been changed or may have expired.
    Recommended action:    Check the following to troubleshoot this issue:
    1) If the agent is not installed on <protected client FQDN>, run DpmAgentInstaller.exe with this DPM computer as a parameter. For details, see the DPM Deployment Guide.
    2) To attach the computer correctly to this DPM server, run the SetDpmServer tool with the -Add option on the protected computer.
    3) If the computer is protected by another DPM server, or if the protection agent has been uninstalled, remove the protected data sources on this computer from active protection. Then, remove the entry of this computer from the Agents tab in the Management task area.
    4) If <protected client FQDN> is a workgroup server, run SetDpmServer with the -UpdatePassword flag on the protected computer and Update-NonDomainServerInfo.ps1 on the DPM server to update the password.
    5) If the DPM server and the protected computer are not in the same domain, ensure that there is a two-way trust setup between the two domains.
        If the computer is protected by another DPM server, or if the protection agent has been uninstalled, you can remove the record of the computer from this DPM server.
        Remove the record of the computer from this DPM server.
