DNS for multiple sites
Our network has two sites, at our home office we have our email server and a second DNS server, our primary DNS server resides at our second office along with our webserver and a bunch of other server, we have our email server at our office just because we don't like the delay in opening up emails especially when there is attachments, anyway our home office was given an IP block of 216.253.xxx.xxx and our server office was given 64.216.xxx.xxx from two diffrent providers. When our DNS servers are queried for mail.something.com only our home office DNS server responds and our primary DNS timesout and when a query for URL only our DNS at the server office responds and the one at our home office times out. I'm relatively new to DNS and my question is, is this how its supposed to work? I really don't think so, both of my dns server have the same entries for forward and reverse. Any feedback would be greatly appreciated.

No this is not normal. Please give me the real domain so that I can test the servers.

I've tested your servers. You have one strange configuration there. UDP requests return public IP's, TCP requests return private IPs under the 10.0.0.0/8 network. One of the UDP requests returned 2 'A' records with the same IP. The situation is also definately as you say it is. Based on this behavior I suppose you're not using BIND. I can't do zone transfers to get a closer look at your zone configuration.
So if you ARE using BIND, I would like to see your named.conf and all *.southwestinet.com zone files. If you are using Microsoft DNS Server, then I'm sorry, I cannot help you.
