DPM agent communication error RRS feed

  • General discussion

  • Hi,

    I have a DPM2007 server installed on Windows Server 2008 Standard which is backing up a file server installed on Windows Server 2003 standard. While running a consistency check, I got the following eror:

    DPM failed to communicate with the protection agent on NMGWW104.corporateroot.net because the agent is not responding. (ID 43 Details: Internal error code: 0x8099090E)

    I checked the records from DPMRA source in the file Server and saw the following message:

    A DPM agent failed to communicate with the DPM service on <server> because access is denied. Make sure that <server> has DCOM launch and access permissions for the computer running the DPM agent (Error code: 0x80070005, full name: <server>).

    I followed the article http://technet.microsoft.com/en-us/library/bb795716.aspx to correct the DCOM launch and access permissions and saw that the agent is a part of the DCOM Users.

    I went to Administrative Tools -> Component Services -> My Computer Properties -> COM Security and checked access permission limits where DCOM Users are given both Lcal Access and Remote Access. I checked the Launch and Activate permission limits where DCOM Users are given Local Launch, Remote Launch, Local Activation and Remote Activation.

    The DPM Server is accessible from the agent. I tried restarting the DPMRA service on the agent also but that did not help. After this I ran a Sync Job again, but now it says 'unable to configure protection'.

    Please help.

    Thanks

  • Hi Community,

    Seems like there was a problem while communicating with the DC. The DPM error was often accompanied by a communication error ID:1053. So I checked the DNS entries and found that the two entries present there were wrong. Backup is running fine after correcting those entries.
