I recently put up an ISA server on my companies simple network. Right now I'm still testing it out, and it only has about 4 computers going through it. For some reason, everytime 3 computers try to get out to the internet at the same time, the connection on the ISA server to the internet dies. Even if I try to get to the internet from the ISA server itself. I noticed that when I ping the default gateway I get no response. If I ping the same gateway from a computer that is not behind the ISA server, I can connect with no problem. Has anyone encountered this problem before?
