Dual NICs internal ping responds to same address

I have two nics in a windows 2000 advanced server. The server itself is a Dell 2650.

Server1
NIC1 172.21.35.60 DNS entry is server1
NIC2 172.21.35.61 DNS entry is Server1a

from a command prompt at Server1 console

if I do a ping for Server1 i get a response to IP address 172.21.35.61
if I do a ping for Server1a i get a response to IP address 172.21.35.61

If I disable NIC2 and do a ping I get a response to IP address 172.21.35.60.

Does this make sense to anyone? I don't understand why this is happening internally on the server.
If I do a ping externally the NICs respond as expected. This is really wierd.

I found that the server was working as was expected. The issue was binding. If you go into Network and Dial Up Connection window and click on advanced then advanced settings I had my NIC's in the wrong binding order. Once I put NIC1 1st int he order that fixed it.
