Before one even has a chance to enter user name and password, an blank dialog box pops up. You can get rid of it by pressing OK, but it is annoying, takes a second, and is completely unnecessary.
I'm using Windows 2000 Pro, SP 2. I've been catching up on a bunch of maintenance/upgrades that I've been putting off and been living with the problem for about a week. So I'm afraid any number of things could have caused it, and I'm not sure what could have caused it. One thing I might mention, I did restore a backup of the registry, but I'm not sure if that was before the box started showing up. I know that it was stupid but I would appreciate any advice you could give me.
