[RESOLVED] Viewing Website within a Domain Server

Good Morning - I have an issue on a server 2000 box. I have run into this awhile back but just forgot the fix. I recently moved the server from a generic file server to an active domain server. Now some of the users on the server cannot view the company website which is of course the server domain name as well. The site can be seen from outside of the domain so I believe it is a dns issue. I did run into this about 2 years ago and another tech friend walked me through the dns setting and I believe the issue was in one of the forward or backward lookups. Can anybody shed any light ion this for me?

Thank you

Chris P.
