Installed programs conflict with DNS
So my server was working just fine as of yesterday, but today for some reason DNS is no longer working. I have no idea why and the only change that was made to the server was installing system-config-date and its' dependencies. I'm not familiar with most of these but could any of them be interfering with DNS?

New DNS Record Not Available Publicly?
BIND is giving me some trouble as I just set up a new DNS record for a domain I purchased a day or so ago. I've gone through the setup many times to be sure, but this domain is set up exactly as the others - both in the named.conf and in the .hosts file that I've set up.
When checking at intodns.com there are multiple problems, including warnings about lame servers and a non-existent SOA record. When trying to get DNS information with the host command it says that the servers are unreachable. I have three nameservers, one master and two slaves, and the slaves are not updating apparently as there is no file for this domain in my slaves folder.
I'm very confused why this one would not work as others did. Any suggestions where I can start to troubleshoot this? I'm fairly new to DNS so I'm not sure which direction to go to fix this problem.
I should add this is on a centos 5 server.
Do you see that bind is listening on the right port on your servers? Any bind config files you could provide would be helpful as well.
I'm assuming that bind is listening on port 53, all other domains configured on the nameserver are working properly - i.e. I can use the host command to find their records and intodns.com returns everything as OK.
