msdfs, win98 / NT and non-resolvable symlink paths

[Shirish Kalele]

Arjen,

I noticed that your dfs links are looping back to shares on the same
machine. This is possibly something we haven't made Win9X clients do before.
Could you try linking to shares on some other machine and see if that works?
