Debian network issue
Overview:
I have an old Debian 3.1 server running vmware server and several VM's. It has been working fine for years with absolutely no issues. Yesterday we had to shut it down to move it to a different location. When we brought it back up, it is able to ping on the local network but not get to the internet. My predecessor was fanatical about security and notorious for "quick fixes" so I am thinking that he either made a change that wasnt committed and thus lost on reboot or he has some hard-coded MAC address somewhere thats keeping this machine from getting to the internet.
Symptoms:
The machine cannot get a DHCP address from the DHCP server (even though it can ping it)
The Machine can PING the gateway and all machines on the LAN but cannot get to the internet
I forgot to add that upon reboot we were getting this error: "tg3 tg3_stop_block timed out"
I googled till my fingers bled but couldnt find a good solution.
Troublehooting so far:
This is usually a gateway or subnet mask issue and I have quintuple checked both
PS -aux does not show iptables or ipchains running
issuing an Iptables command results in "command not found"
issuing an ipchains command results in a "not compatible with this kernel"
I have not been able to find any other firewall related configuration
Multiple other machines plugged into the same switch can successfuly receive DHCP addressing
Those machines can also get to the internet just fine
Does anyone have any advice at all? I have been working on this for about 42 hours straight and am at my wits end. Are there any other services that could be stopping the box from getting to the internet? I would be so appreciative for any nudge in the right direction!

It the gateway hardware isn't the same identical hardware, I'd compare the configs on both.

I ifdownd eth0 and brought up eth1 and it works perfectly...no idea what was going on but I am not going to troubleshoot further since this is a temporary install.
Thanks very much for all the responses and help.
