one or more prerequisites for protecting this data source is missing RRS feed

  • Question

  • I am using DPM 2007 and just installed the agent on a Windows 2008 R2 server. When trying to add the system state backup I get this error:

    One or more prerequisites for protecting this data source is missing.
    Ensure that the following prerequisite software is installed on server and/or all nodes in the cluster:

    Windows Server 2003 SP1 with Knowledge Base article 940349 (
            - OR –
    Windows Server 2008 (

    If you have already installed the required prerequisite, refresh the agent status in the management tab and try again.

    I can do a system state backup with Windows Server backup, just not DPM. I have other 2008 R2 servers that have not had this issue. Any ideas?

  • Hey,

    Could you provide us with a bit more information?

    Which roles are installed on that 2008 R2 server?

    Did you install on your DPM server (latest QFE)

    Is it a cluster?

    Thanks in advance,
