[Samba] Win7 SLOW printing

[Ryan Suarez]

Ok, it looks like this was the cause of the delay.  As soon as I disable 
windows firewall on this client, the errors disappear and jobs start 
printing immediately.  We have bring your own laptops (with their own 
image) here at the college.  I suspect this is the same cause of their 
delays.

Could someone please shed some light what samba uses this connection for?
