We are running an NT4 domain with a domain name in the following format: My_Company (no extension). We also have a Web site located outside our domain with a Web service (Verio) called mycompany.com. We have not yet implemented DNS.
We are preparing to go to a 2000 Network and have been told that we need to rename our domain without special characters like the dash or underscore.
What is the best naming convention for our domain and the DNS suffix? We will keep the web site as mycompany.com and plan to name both the internal domain and dns suffix mycompany.com too. What are the pros and cons to this? Should we consider a different name for the dns suffix?
