In our company we have Windows 2000 Workgroup. We are thinking of moving to domain model. Now my company website and mail server is hosted on third party server. Our windows 2000 server also act as gateway for the network. We have permanent internet connection through this server. I am confused little bit about how to configure my domain server and DNS. Because I think if I name my domain as xyz.com wouldn't it will clash with other IP address that our third party uses to host our site. When we move to domain model we are also thinking of hosting mail server locally.
