I manage a school network running XP with Office 2007. When users open Word or PowerPoint 2007, it asks for their name and initials like it would the first time they opened it, and the users enter them as usual. But then Office starts asking for them again and again every few seconds, making it impossible to accomplish anything. I have no clue what would be causing this to happen, as we've had this setup for over a year now and it just started happening. Any help would be appreciated.
