    Login issue (XP/SP2)

    When I login as anyone else besides an administrator I get a blank screen. IF I Ctl-Alt-Delete and push cancel the desktop will come up as it should.

    Any ideas about what is going on and how to fix it?

    Thanks.

    I've not run across this one yet. How about a quickie test to see if you can "jiggle" Windows' memory a bit. If you're using the Welcome Screen, go to Control Panel and change to the traditional, or vice versa. Re-boot that way and then change back. From what you say, it doesn't sound like a (badly) corrupt profile.

    That did not change anything.

    Another clue is that whenever I logon as a regular user the mouse cursor shoots up to the top left corner of the screen. That tells me that I will not get the regular desktop screen.

    OK, I've got to do a bit of Googling at a few places on this one. Hang in to see if any other Lounger has an idea also.

    And hey, I forgot to say WELCOME to Woody's Lounge!

    Does this always happen?
    Is this a new issue, or since installation?
    How many other users do you have, and does it affect all profiles?
    Are you on or logging into a network?
    Does there appear to be any disk activity when the screen goes blank?
    After hitting Ctrl-Alt-Del, select TaskManager. Does the 'normal' screen come up? Can you see any unusual activity in TaskManager?

    This is not a new install. It is a computer in a school computer lab. I discovered the problem today.
    There are multiple users. The same thing happens to every user I have tried. I have tried both network users and local users. It appears that anyone who is not an administrator ends up with a blank screen with the cursor up in the top left corner. When the blank screen appears the cursor has the hourglss next to it and it stays with it until the cursor moves to the left top. Pushing Ctl-Alt-Delete and then tast manager makes the normal screen appear. Pushing Cancel also gets you the normal screen.

    Sounds like it is trying to load a corrupt program or piece of malware and is having a bad time of it.

    Have you tried to "wait it out" for a while to see if an error message eventually come up?
    Have you run a good spywaremalware utility on it recently?
    Checked the Admin Event log to see if anything shows up with a flag on it?

    Wait it out doesn't produce anything.
    Other than ad cookies I have found no malware. What free spyware would you suggest?
    Sophos, Adaware, Spybot and Spysweeper have found only cookies.

    Re: Login issue (XP/SP2)

    This is an OLD recollection! It seems to me that I had an erratic mouse cursor problem similar to yours a LONG time ago and it had something to do with the AV program I was running at the time. I no longer remember if it was McAfee or Trend Micro. Which AV program are you running on this machine? What if you (holding your breath!) disable the AV program and try logging on to see if the problem's still there. Of course, you WILL turn it back on as quickly as possible, but just to see if it IS involved in the problem.

    I can't come up with anything in my Googling around. One other thing to try. Suppose you logon as an Admin and then lock the machine with a WinKey-L THEN try logging on as a limited user to see if the mouse still goes nuts or if the screen is blank. Given that it doesn't happen with an Admin makes me think it not corruption, but software interference for limited users. As you can tell, I'm fishing...

    The spyware progs you mention should have picked up any problem in that area.

    How about the Event log?

    Control Panel>Admin Tools> Event Viewer.

    Look in the subcategories, Applications, Security, System, etc and check for Event failures that may give you a clue to go further.

    Re: Login issue (XP/SP2)

    I figured it out.

    After I could not find any malware, I decided to try deleting programs one by one. After deleting Sophos, I deleted Fortres, our student security program. That was the bad boy. Something must have been corrupted. After reinstalling it, things are back to normal.

    Thanks to everyone for your help.
