MailSweeper for SMTP on the ISA box?Please help me with this: We have servers outside the ISA, in the same subnet that it's public NIC (connected to the internet). These servers periodically send a broadcast to UDP ports 137 and 138, they are windows nt using netbios of course, and the ISA is blocking those broadcasts, may this be causing problems? If so, how can I fix that? Thanks!!
