outdate Dfs links and d registry clean up

Adding a new Dfs link results in some new keys to be added
to the registry; the new keys are added under
<HKEY_LOCAL_MACHINE\CurrentControlSet\System\Service\ntFrs\
Replica Set.

But, it seems that when the Dfs link is removed from the
Dfs toplogy, the registry of the server that hosted the
deleted shared does not get cleaned up. Any idea if there
is a fix for it (other than manually removing the keys
from the registry).

thanks,

Fari
