I have a Windows 2003 server box with MS DNS server running. The server is configured with two IP addresses and the DNS server is configured to listen on both. The problem is one IP responds to the queries correctly but the other does not (although it does reply, either the reply is empty or is different from what expected). The queries made at the second IP do not show up in the DNS log either. I can connect to other services running on the server on both IPs without problem.

I presume you have set up the same DNS instance to serve the same zone(s)? If so, be sure to set up zone transfers accordingly. The primary server 'master' should be allowed to transfer zone information to the secondary one 'slave'. You can also set-up DNS notify, so that the master knows whom to provide the zone info to should changes be made to the zone file. In this regard, you should also check that proper security settings are in place -- e.g. the master should be allowed to transfer zone information the slave's IP and vice versa. Hope this helps!
