w2k small biz server, less then 100 nodes all on same subnet.
last monday 1-3 users started being kicked off the network. usually just 1 user in particular, but others have went down a couple of times too. while they are down, nobody can browse the internet either. I installed capra packet sniffer to try and isolate. i am seeing alot of netbios ssn traffic. unfortunately, I don't work at this site all of the time, and by the time I get there, the problem has went away, i have been there once while it happened, but that was before i installed capra. it always happens in the afternoon and goes away from 15 min, to a couple of hours later.
