Can't umount a mounted file

[Glen Lee Edwards <glenlee perluser net>]

I have a LAN file system mounted on 6.1 from a Win95 PC through Samba.
Problem is, according to mount it isn't mounted.  I can access the files
on the Win95 PC and add or delete files with no problem.  How do I umount
it?  Is there a manual override somewhere?
