Zone Alarm

[Dr. G]

Uh, If I am not mistaken, Port 139 is used for NetBios, hence you have
computers lookng for a Netbios connection on your PC. I also run ZA on my
WIN2K box, and I get this ALL the time from my other PC's on my LAN. As long
as it's internal, and you recognize the IP, it's no biggie. It's when it's
NON-LAN Ip's that you want to be careful, because some pc out there is
trying to locate a share on your PC.
