DPM 2012R2 - Unable to install agent on trusted domain RRS feed

  • Question

  • Hi,

    I'm pretty sure I'm not the first to ask this question, but couldn't find the solution anywhere.

    Just completed the installation of DPM2012R2 and I'm trying to install\attach agents on the computers from the list.

    Every single computer is returning me the same error: 322,

    The following computers <computerame> were not found in Active Directory Domain Services, or they do not have a Windows Server operating system installed.

    Which is weird since I'm logged in as domain admin and was able to access all the hosts under my active directory domain with no problem.

    Any hints?

  • Hi

    Are there any firewalls enabled? Are all machines in one subnet or spread across others?

    Run the following command to test WMI communication from the DPM server to the server you are trying to protect.

    Wmic /node:"<protected server name>" OS list brief

    If this fails then we have verified that it is a network communication problem

  • Hi,

    Few things to try:-

    1. Temporary disable Windows firewall between DPM and target server

    2.Try add the credential that you use to push DPM agent to each local server-Local Administrator Group.

    3.On DPM server server, make sure can resolve FQDN of the target server and able to ping them.

    4.Next, depend on your target server, you may need to install some pre-requisite software/ update.
