WARNING: Update 969947 may prohibit establishment of an RDP session on Windows XP

Discussion in 'Windows Update' started by David Dickinson, Nov 11, 2009.

  1. I tested KB969947 on a Windows XP Professional SP3 machine that is reserved
    for testing. After installing that update, I could not log on to it in a
    Remote Desktop session. In fact, the machine had frozen and could not even
    be accessed with its keyboard or mouse, and the hard drive light flashed in
    a repeating pattern over several minutes. However, after restarting the
    machine, I could log on to it locally. After uninstalling that update, RDP
    sessions were successful. I reinstalled it and tested again, and RDP
    sessions failed. After uninstalling, they worked.

    Test this update thoroughly before deploying it! I've notified Microsoft
    about the issue, but the help that is available at this time told me that
    Microsoft Enterprise will have to deal with it, and I have to wait until
    normal business hours tomorrow to contact them.

    I haven't yet tested this update on other versions of Windows, but I hope no
    adminstrators have large networks using automatic updates. I'm just hoping
    that this isn't the disaster that it could be.

  3. Thanks, but as I said, I've already contacted Microsoft about it. I've got
    a support request number and everything. But since the Enterprise group
    only works during daylight, I have to wait until then to contact them...

    ....which strikes me as strange. Home users can get help 24/7. But if
    you've got a problem that could affect thousands of computers, your problem
    has to wait.

    we're having the exact same problems here on several machines. I've had to
    boot to safe mode to get it uninstalled then everything is back to normal. I
    would advise to disable the download of that update at this point.

  6. Not repro-ing that here.

  7. Second machine tested. Can't repro on second box.

  8. I have two XP Pro SP3 test machines. One has the problem, the other
    doesn't. I haven't been able to isolate the cause yet. The machines have
    significant differences in their configurations, so it will take some time.

  9. Recently I had an issue post .net patch that I could not RDP. It was
    due to the monitor card software interaction with 951847.

    Look in your event log on the workstations and see if you are getting
    that error.

    After the install of KB951847 (.net family) I found I could not rdp into
    a XP workstation. Updating the driver didn't work but putting in the
    registry key did:

  10. I had considered display driver problems, but that's not it. With 969947
    installed, the machine freezes during RDP logon. Without 969947, the
    machine works fine. There are absolutely not messages in the event log
    relating to this issue. The security log doesn't even show the normal logon
    attempt messages. As soon as I enter the password to logon in a remote
    desktop session, the machine freezes.

  11. You said you had a case open right? If not ping me and I'll get you
    one. Can you let me know what they say?

  12. This machine has an nVidia GeForce 7050. But the symptom you describe is
    similar to what this machine experiences. Perhaps there's a problem with
    display rendering in an RDP session when this update is installed.

    I have seen a problem where after installing 969947, the PC will
    lockup shortly after you login. I was able to uninstall the update in
    safe mode.

    This has only occurred on PC's with an ATI Radeon HD 2400 series
    cards. Upgrading to the latest version of the driver (9.1, released
    10/22/2009) and then reapplying the 969947 update seems to fix the

    Just my .02

  13. I spent two hours on the phone, including hold times, with Microsoft while
    they transferred me to different departments. PC Safety says its a business
    problem since it involves RDP. Business support says its a PC Safety
    problem since it involves an update. Then we got disconnected when a guy's
    headsets failed. I can't try again until tomorrow. I am not a happy guy.

    I'll post an update when I learn something.

    I'm also having the exact same "lockup" issue. XP Pro SP3, Fully patched. I had to hard boot the machine, uninstall the patch, and it started working fine again.

    I also have a GeForce 7300GT video card. NVidia Driver:

  16. You have a different problem. Try resetting the RDP session with this:

    echo yes | reset session RDP-tcp

    If it happens a lot, then you've got a corrupted installation. A
    repair/reinstall of the OS should fix it. Unfortunately, I don't know of a
    better solution.

  18. @David: Are you aware of the annual Global Technical Support package benefit
    and did you avail yourself of same to get assistance with this? cf.

    PA Bear [MS MVP], Nov 12, 2009
  19. @PA Bear: Yes, thanks, I do know about the benefits. But I haven't been an
    MVP since 2002, when my business expanded and I just couldn't keep up with
    the forums. Not being an MVP anymore, I don't qualify for the package. But
    now that I've been able to delegate some of my more tedious
    responsibilities, I hope to have more time to spend here. I'd forgotten how
    much I enjoyed it.

    We have a similar problem. If I login (without RDP), the machine
    freezes. In safe mode it is possible to uninstall the update. Than the
    problem is solved. In this department we have about 20 PC's. Only 4 of
    them got this phenomenon. At one of this PC I was unable to start the
    safe mode. Only the Recovery Console gave me the possibility to
    uninstall the patch.
