I have had this happen twice so far, and I'm beginning to wonder if it will continue happening on each PC. We have a Win2k domain all our users connect to. Now, we have one user who, when they came in and tried logging in, gets 'Windows cannot connect to the domain, either because the domain controler is unavailable, or because your somputer account was not found. Please try again later. If this message continues to appear, contact your systems administrator'. If you use another name from the domain that was perviously set up (such as administrator), that username can log in once, but if they log out and try logging back in, that username starts getting the same message. This also happens if you use a local username, not one on the domain (log in once fine, then can't log in). The last time this happened (last week), I ended up reformatting the workstation and reloading the PC, after using a local admin password blanker CD to reset the local admin password on the PC, and log in that way to copy off the users local folder under documents and settings. Any ideas would be appreciated, I would rather not have to format another PC because of this.
