OH MY GOD!!!  I can't believe it was that easy!

I added the global spec "nt status support = no" and the software runs 
great.  You have saved my sanity!!!!  What a profound pleasure it will be 
to remove the last of the Windows servers at our branch offices.  I can't 
wait to start in on my big Compaq rack of NT boxes at the main office next.

Besides doing Microsoft style networking better than Microsoft, you Samba 
folks are kind enough to offer your expert help.  I can't thank you enough.

Cheers,

Mike
