I have a had name server set up for my websites on my server but a while back the I put a new network in and it stopped the name server from working. I didn't have a back up name server off site so I just used cheapname.com for my dns server. This worked well until I removed the new network card because it didn't help me and was causing more problems. I put all the settings back to what they were before with the old network card and now the websites are down.
I have checked on http://www.whatsmydns.net and it shows that the web-sties are not propagated. The only thing I can think of is that the two name servers are not getting along. I am really new to dns so I just need to know if this could be the problem and what needs to be changed. namecheap.com doesn't support zone transfer so I have went through and matched the records on my server and theirs manually. the only thing that I haven't matched is a line in the bind config files for the websites that is ns3 then my ip.
I am running a Ubuntu server with bind and apache.
