Unstable network connection
At the moment I have RACK A with windows boxes connected to a cisco 2620 switch, and then an optic fibre, and then RACK B.
The optic fibre goes through a cisco firewall first, and then to a switch, and then to a network of windows machines when it hits RACK B.
When using ftp, or viewing a media stream, and sometimes even using mIRC or ICQ, the connection drops out intermittently.
If you have any ideas I would love to hear them.

So,
Rack B contains the Cisco firewall, which connects to rack A via fiber?
Meaning, Rack A doesn't REALLY connect to Rack B, but connects vi fiber to the Firewall which is part of Rack B's copper network?
Is that the correct picture? If so, then what you are saying is that devices in the Rack B network can do all sorts of stuff without dropouts or errors, but devices on the Rack A network experience intermittend dropouts?
If that is the case, then I would specifically look at the fiber-optic link, as suggested by Robing6606 and chicagoan. It could be in the cable itself, in the cable terminations, in the fiber-to-copper converters (if any) or in the fiber interfaces/WICs (if any.) This does not say anything but "hardware problem" to me.

We still don't know the entire problem, but chicagoan's suggestion of checking the speed & half/full duplex settings was good - it was a contributor. Thanks.
Replace your cables and see what happens.
