Hello,
Actually i have this problem with my Windwos 2008-R2 file server and i applied the actions mentioned in this article:
http://support.microsoft.com/kb/281308/en-us but till now i couldn't access the shared resources using its unc from XP and Win2K3 machines, getting the "duplicated name existed on
the newtork.." . on the other hand, i can access this share normally from my Win7 machine.also, this shared is rechable using the same unc but with host name instead of alias 9cname).
thanks
Najee
