[Samba] unmounting unmountable shares

[Andrew Gaffney]

I have 2 shares on an XP Pro box mounted using smbmount on my Linux box. The Linux box is 
also the PDC for the domain. I have 2 mounts that I can't get to unmount, no matter what I 
do. I've already tried killing off the smbmount processes associated with them. When I try 
to do 'ls <mnt dir>' it tells me that access was denied. Is there anything I can do short 
of restarting the box?
