I would check the Event Viewer first. If that happens again, I would =
check the IP, DNS, subnet and default gateway.

Hi everyone,

I'm having problems that I don't know how to diagnose. Today, our
network went down. I have no idea why. I figure it must be some cable,
switch, or hub - or maybe even a network card.

Our network starts with a server running OpenBSD that provides VPN and
firewall. That box also connects to a 16-port switch. From that =
switch,
many other hubs and switches are connected, which the computers =
connect
to. Of of the switches are connected to our DS server.

When our network went down, I first tried to ping our DS/DNS/DHCP
server. Nothing. Next, I tried to ping our gateway. Nothing. I
restarted the DS server and now everything is fine.

Where do I start?=20

Help much appreciated.

Regards,
Mike.

This set of steps is redundant in many places, and it's also enormously expensive, since you're using no less than three different expensive bits of networking hardware (AP, PIX, VPN Concentrator), in addition to a bunch of x86 server hardware, windows server licenses, and at least one ISA license. ...
