I have an issue that I would like help from anyone. I have a Win2003 server that is my DNS,DC and my Exchange server. My internal domain(x.com) name is the same as my external domain(x.com) name and from what I have heard its not safe to have it like that. I need to know how to secure my DNS and domain.
Secondly how can I change my domain/dns name to x.local without losing data or should I say in the safest way possible.
