Interesting thought -- this seems to happen when the user logs in. I tend to think the client machines are configured to automatically cache all the crud in 'My Documents' onto the local machine (which is a really lame idea). But I am still mystified why one file would have to be stat'ed THOUSANDS of times. Anyway, I'll look into it some more today and I'll see if there is some dopey anti-viral software installed.
