How to get Website to use domainname only

[SysAdmMke]

For some reason, it I go directly to my web site internally name without

http://www it

displays fine. When i tried it on the outside with www, it works but without the

http://www and

just the domain name, it says page cannot be diaplayed. Where do I configure this to not use www? Is this in the listener properties? This is for ISA Server 2004.

Thanks
Mike
