New NICs and routing issues

I had to replace a couple of NICs in my server and now it doesn't appear
to route between them. I did not unistall the nics before replacing
them (I am not sure if this makes a difference, I hope not). The new
cards have the same IP info as the old, so I am not sure why the routing
doesn't work. If more info is needed, let me know.

Thanks.
 
We need more information to help. Posting the routing table here may help too.

Here is the routing table. The problem is that a user (on the 20
network) uses this router to route to the machine with the IP address of
67.39.168.135. I can ping this address from the router OK, but I cannot
ping that address from the users PC.

the routing table doesn't make sense or doesn't work the way you want to. Did you point all NICs to 67.39.168.135? we need one more information, ipconfig /all.
