After I run a print job or I open "Printers and Faxes" I see new activity in my PC's firewall. I see about 200KB/s both inbound and outbound for 3 seconds out of every 10 between a port on my machine (a different port after every shutdown or after shutting down network traffic) and port 445 on the Samba server. Is this normal? (I hadn't noticed this before, but I'm noticing new information ever since upgrading to the latest version of Kerio's Firewall--now owned by Sunbelt software.) Boaz
