Scroll down to the section "Troubleshoot access to files and shared folders:" It lists a few things to check, but doesn't go into details about fixing things.

This link has several pages of descriptions of what can give the 537 Audit Event ID. http://www.eventid.n...=Security&phase=1 Perhaps there's something there that helps?

I think that if the permissions are messed up on the client, you'll have to manually reset them (or restore them from an appropriate backup). I don't think you can have it done automagically, but that's just a guess.

Good luck.

Cheers,
Scott.
