I have three machines with QB2006 installed. The two that have not had the any updates installed can connect to a Samba share. The one that is fully updated gives this message when attempting to connect to the Samba share:

"You are trying to create, open, or use a company file that is located on another computer. Your computer is set up to allow access to only those company files that are located on your computer"

GROAN!!! Why did Intuit mess up a decent product?
