Is it a game server? I.e. Quake, UT, Tribes, RTCW... If so, this may be your problem. When the (usually UDP) traffic from the server telling all the players who's doing what and where, any dialup or other slow connection users' system probably gets cranky and begins begging the server to slow down. I also see this same behavior on our Tribes and RTCW servers. Usually coming from the same few slow ISDN users.

I get about 5-6000 ICMP Source Quench alerts a day(!)...all from one of their NT servers sitting on the same subnet as mine. I'm not sure what role the NT box serves for them, but it certainly is chatty with my box. All I know about source quench messages is that they're an indication that the sending box isn't handling the volume of traffic very well, and it's trying to tell my box to slow down. And I know that ICMP Source Quench packets are "depricated", since it's not a great idea to generate more traffic to indicate that there's too much traffic. That's the extent of my knowledge about ICMP Source Quenches. While I could have Snort ignore these "violations", what I'm really wondering is WHY the NT box would be having so much trouble with this server...it's NOT a very high-volume server at all (2 web sites, one quite negligible). So I have a hard time believing that I'm really flooding the NT box...or rather, I can't believe that the amount of traffic my machine is generating is unreasonable. Can someone fill me in on what I might be able to do to resolve this issue, either on my server, or the network it's on, or the NT box (I don't have many details on the NT box right now, but I can get them).
