On the NT box or when doing it over smbfs? If not from smbfs it is
probably "immortal" only to the application you were using to delete it

Samba does not fake inode numbers, smbfs does. And the behaviour is
related to dcache/dentries too, not only inodes. It is possible to create
a directory and get the move to fail with the expected error message.
Btw, be careful when doing operations over smbfs to a deep directory
structure. Before 2.2.18-pre15 there was no checks that the pathlengths
remain within the fixed buffersizes of smbfs (of smb/cifs ?). You can
easily crash your linux machine by doing that.
