I just obtained a Windows Server 2008 VPS. Rightly or wrongly I followed instructions from the host to set up custom name servers. So now I have ns1.mydomain.com and ns2.mydomain.com. The are both the same since I have 1 IP address. I have A records for www, * and a few others, no MX since I use Google Apps. I pointed my registrar that has mydomain.com to ns1.mydomain.com. All is well that works.
The problem is myOtherDomain.com. I set it's DNS on the registrar to point to ns1.mydomain.com and in IIS give it, it's own website and configure bindings with host name of myOtherDomain.com and www.myOtherDomain.com. I thought that was all I'd have to do. Apparently not. Do I have to add something else to the DNS Server? Should I have another custom name server? Since they are pointing to the same IP I figured IIS would untangle things with the host headers.
The site is php, not sure that is the problem though.
