documents folder redirect

I have a user with Vista Business in a 2003 AD environement that recently
had to recreate his documents folder.
We have his documents folder on a 2003 server as a mapped drive u:\userx.
After we recreated it, it shows contents in my documents, but when another
user browses the share it shows up as u:\documents. From the server
itself, it shows as u:\userx. The user also has offline sync. Havent
seen this before, but most of our clients are still XP. Can anybody clue
post any information related to this if they have dealt with it before
Many Thanks
