Windows XP clients are unable to talk to an application on Windows 2008 Server

    Question

  • We recently did an Domain and Forest Function Level upgrade from Windows 2003 mix environment to Windows 2008 R2.  Since the upgrade the XP client application is unable to connect to the server  application the Windows 2008 Server, error message on the server :

    Could not connect to DMOutlook: HRESULT = 80070721

    FACILITY = FACILITY_WIN32

    RPC_S_SEC_PKG_ERROR

    A security package specific error occurred.

    If we try connecting using a Windows 7 client everything works fine, I also build and Windows 2003 Server and installed the application on it and it works fine.  Please help

  • As Mr X said, it can be the application issue and its best bet to contact them first. I haven't heard just upgrade of the DFL/FFL bars XP client to connect to the DC and authenticate.

  • Did you move the app to 2008, or was it there all the time?

    Did you change around DNS addresses at anytime?

    As others mentioned, changing forest and domain levels DO NOT affect communication. They only add cool new DC to DC communications and AD features that enhance DC funcitonality.

    .

    I also vote you contact the vendor.
