Reinstalling is _almost_ never the answer.

Your eth1 needs an IP address which is valid for the network it's connected to, as well 
as a valid gateway address (the IP address of a router which "knows" how to reach the
Internet). It also needs to be able to connect to a working DNS server.

So ... does that NIC have a valid IP address?
Can you ping the router?
If no, then there's a connection problem of some sort between the LTSP server and the router
If yes, can you ping 216.239.41.104? (www.google.com)
If no, then your router is either not talking to the Internet, or not configured to allow your
server to reach the Internet.
If yes, then can you ping www.google.com?
If no, then you have DNS problems. What "nameserver" (maybe more than one) is listed in /etc/resolv.conf?
Is it a valid IP address? If "nameserver" is pointing the your LTSP server (127.0.0.1, or 192.168.0.254 (if
you're using the default address), is the named service running?  Try "dig www.google.com" - what's the result?

If you can answer any of these questions, we can probably get you going.

It might also help if you can post (or email to me) the results of:

1) /sbin/route -n
2) cat /etc/sysconfig/network-scripts/ifcfg-eth0
3) cat /etc/sysconfig/network-scripts/ifcfg-eth1
4) cat /etc/resolf.conf
5) /sbin/ifconfig
