We have a small situation that may require us to temporarily host DNS requests on a temporary server for a customer's domain. We think we can use our SBS 2008 to do this. I've proven it can work, in theory, but I'm wondering if I am not anticipating something.
The situation, in case anyone has a better answer, is thus:
We are attempting to move a domain name from GoDaddy to Network Solutions. Predictably, we want to minimize downtime. The domain name in question has a few DNS related records -- a couple of As, a few CNAMEs, MX, and one SRV.
When I spoke to NetSol, they stated that there was no way I could alter anything DNS related on their side until the domain transfer had completed. So, I would be likely to encounter a domain name waking up in its new home with no DNS records available to keep mail flowing, web site accessible, etc.
They suggested we host DNS temporarily at a way-station of sorts.
I created a new ZONE in my SBS2008 along with all the A, CNAME, etc. records for the domain. I tested via NSLOOKUP and confirmed that accurate information is given both when I query against the server internally and when I let DNS queries through the firewall and query from the outside.
I believe all I really need to do now is change the nameserver entries at GoDaddy.
Am I not anticipating anything?
