  • Question


  • DPM 2016 with the latest rollup
    Protected servers (PS) with Windows 2016
    
    PS is located on a different network but a part of the domain
    
    When trying to install the DPM agent I get the below error.
    The machine is accessible from the DPM server
    Firewall is enabled but exceptions are set - WMI is running and have exceptions set
    Manual installation of the agent fails with that its not finding the DPM server
    
    Error in DPM:

    	More information
    Recommended action:	Do the following to troubleshoot this issue: 
    1) Verify that machine.contoso.com is remotely accessible from the DPM server.
    2) If a firewall is enabled on machine.contoso.com, make sure that it is not blocking requests from the DPM server and has an exception for Windows Management Instrumentation(WMI).
    3) Try installing the agent manually by selecting "Attach Agents" in the agent installation wizard.

    Error on PS

    A DPM agent failed to communicate with the DPM service on DPMServer.contoso.com because the host is unreachable. Make sure that DPMserver.contoso.com is online and remotely accessible from the computer running the DPM agent. If a firewall is enabled on DPMServer.contoso.com , make sure that it is not blocking requests from the computer running the DPM agent (Error code: 0xa58ad070, full name: DPMServer.contoso.com).

  • Hi,

    This issue can occur if your DCOM channel is not working properly or your firewall exceptions are not added correctly at the protected server side.


    Check the following:

    1. Can you ping the DPM Server from the protected server?

    2. Did you try installing the DPM agent manually? If yes, then configure firewall in your protected server.

    For firewall configuration requirements, see Deploy the DPM protection agent:
    https://docs.microsoft.com/en-us/system-center/dpm/deploy-dpm-protection-agent?view=sc-dpm-2016

    Best regards,
    Leon

  • Thank you Leon.

    Found out that RPC was blocked one way (from PS to DPM) in our application firewall.
