Does Win2k SP4 introduce the webclient service? There has been quite a
few problems lately with XP, the webclient service and Samba.
Does your firewall see any traffic on port 80 when the users are
connecting to the printer? We had a similar problem with network shares
timing out for 3 minutes exactly - turning off webclient, (or not quite
so good - enabling port 80 on the firewall) solves the problem. Though
I'll say again, that was XP.
