After setting up new GPOs over the holidays to take over from our CC3 install which is now all but gone (yay!) I came across a strange problem. When anyone logged in their home folder (setup in AD) was redirecting to the root of the share and not their folder as specified. After lots of investigation it looked as if it was a problem with group policy and the time taking to apply to the local computers. Sadly this was just a case of misdirection. If you are having the same problem may I suggest you take a look at the link below as it solved my problem straight away.

The Home Folder may be mapping incorrectly when logging on to a Windows XP-based computer
