I have a user who is having presence problems. She cannot see anyone's status, and she sees herself as unavailable. When she first logs in, I can see her status as online, for a least a few minutes, and I can IM her, and she can respond, but she cannot initiate IM's. But after a few minutes, it seems, I see her as off-line again. Also, when she tries to generate a problem report, she gets an error that refers to a file named CUERT (I didn't note if it was a .dll or .exe). Anyone seen anything like this before?
