Specific help is needed with a very serious and complex problem I have been having for about 2 months..

Scinero : Say I have one NT server. Dual NICS. NIC1 - 3com 3C905B - IP address 207.x.x.x NIC2 - Linksys - IP address 10.0.0.1 Say this NT server is a MS proxy 2.0 server. Been working fine the past year.

Problem : I turned this machine into a redhat 6.2 box. Same NICS, same cat5 cables, same patch panel, etc. The first NIC with the live ip (207) works great, pings internally and internet sites. On the other hand, the SECOND NIC doesnt' work at all. It doesn't show errors on boot up. Yet when i "ifconfig" it isn't up. I "ifup eth1" and it says "Network unreachable"

I have tried 20 different kinds of installs. I have tried different nics. I have tried different cat5, different ports on the switches/patch panels. I have tried everything. What is wrong? I know the Linksys cards work, because some of my other redhat servers (with one nic) have linksys cards. I do a "dmesg" and everything is on a different IRQ, so its not that. What I am doing wrong?? I have converted an ALL NT network (30+ servers) all to redhat 6.2 There are 3 Proxy servers I want to change then I'm done Please help! I'll be watching for responses incase anyone needs anymore information.
