I've got a server running Windows 2008 R2 Standard. We've got some consultants setting it up for BizTalk 2010. It's part of our internal domain (internaldomain.mycompany.biz). Since we needed an SSL certificate for BizTalk, we purchased one along with an external domain name (mycompany.biz). While the consultants are working on the server, they have noticed that they will occasionally lose the ability to resolve the domain name (mycompany.biz). I have a feeling that this is due to the fact that the internal and external domain names are mostly the same.
Here's what happens:
1. The consultants open Internet Explorer on the server and go to " (5556 is an alternate SSL port.)
2. It will eventually say that it couldn't find "mycompany.biz". Ping and tracert won't resolve "mycompany.biz", either.
3. I change the DNS settings on the network adapter from our internal DNS servers to some public DNS servers.
4. " will now go to the appropriate site on the server. Ping and tracert now resolve to the external IP address.
This leads me to the following questions:
1. If I set a hosts entry on the server like "123.123.123 mycompany.biz", will this interfere with the server's ability to work properly on the internal domain (internaldomain.mycompany.biz)?
2. Would it be better to modify some records on the DNS server, instead? If so, what are the settings?
3. Would it be better to use a different external domain for the server ("somesubdomain.mycompany.biz" instead of just "mycompany.biz")?
If I haven't explained this adequately, just let me know and I'll try to fill in the gaps as best I can.
