DPMRA Event 84 RRS feed

  • Question

  • I have a problem with non domain Protection Server.

    When DPM server tried to contact agent I get an error on Protection Server DPMRA 84:

    A DPM agent failed to communicate with the DPM service on because access is denied. Make sure that has DCOM launch and access permissions for the computer running the DPM agent (Error code: 0xa17b90, full name:

    I think that there is no problem with connection from DPM Server to Protection Server.
    wmic /node:"Protection Server Name" OS List Brief             is working OK

    When I tried the same thing using administrator account (local administrator passwords on both servers are the same) on Protection Server:
    wmic /node:"DPM Server Name" OS List Brief             I get Access denied, although nothing is wrong on Event Log: Security.....
    I can connect to administrative shares on DPM Server from Protection Server.

    I think that DPM Server can contact agent, but agent can't respond to DPM Server.......

    Thanks for help in advance!

  • add an entry in the firewall which allows all traffic from the DPM server ip address and try again
