hi,

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.  

any ideas?

thanks, Ross

no backups.  I havn't been able to observe the problem since installing capra.  It went down today, I tried to get in via terminal server but it wouldn't let me, which I figured would happen since the internet was down.  I could still ping the external address of the router though, so I know the problem isn't with the isp.

This happens every afternoon? After happen then near those clients? Anything that could be an environmental variable perhaps? Like they are near a generator or something goofy that kicks on and causes crosstalk to kick them off. Or maybe its near the server.

no changes like that afaik, I will ask about that though.  this just started last monday.  they use norton corporate, and it is up to date or I would have thought it was some weird virus.  I checked the main users pc that goes down completely the most for spyware, nothing too bad was in it.

i fixed the problem.  It finally went down and stayed down while i was there allowing me to troubleshoot deeper.  I traced it down to one part of the building that is fed by one wire to a hub.  the wire was going through a surge suppressor before going into the hub.  I plugged the wire into the hub directly and the problem went away.

I still don't know why it would only go down in the afternoon, but as long as it's fixed, i'm not going to fret over it.

I am going to close this now.
