looping folder

I had a folder call "users" on the root of the server call "home". The root
had a share name "file". When I open "users", it show the whole root of the
server. I can open up "users" about 20 times and it still show me the root
of the server, with another "users" in it, until Explorer said the path is
too long. I checked the properties of "users" and it show "\\home\file".
The server was a w2k before and someone upgrade it to 2003. It was before I
got there. Any advice on how to fix this? Thanks.
