As far as we can tell, all of the affected clients rebooted due to updates…

It's weird, it ONLY affects the [homes] share, nothing else is affected. It only affects user initiated changes,

for example, you right click in the share, create a new word doc. The document gets created. Edit the doc, and try to save, you'll get permission denied, however, Word successfully creates both a tmp file and a backup file.

Right click on the share, create new text file, you can open, edit, save no problems. Gvim even manages to create backup and swp files. But you cannot rename the text file.

For the affected folks, I've created their own share [dkrause] pointing to the exact same directory, then the problems go away. But I'd rather not do that for 60 people.

Our security is ADS, the testjoin succeeds, all non-home shares still behave.

The relevant portion of the smb.conf: (the dkrause share is a test, which works..)
