NT DNS not resolving certain domains

[Larry Buss]

Hi folks

I have looked at my DNS server config over the past few days and cannot find
anything obviously wrong. Perhaps some folks here can give me a clue as to
what my problem may be.

I am unable to resolve certain domains. For example I receive a DNS server
not found error when I browse www.microsoft.com, but when I browse
microsoft,com the page loads. Another instance is I am not able to display
www.rolex.com, again I receive a DNS server not found.

I am able to ping the above sites via their Ips, but not their domain names?

My DNS server is also my email server. I have not had any problems
sending/receiving email.

Anyone have any clues as to what may be causing this?

NT 4.0 sp6 DNS
Win98 clients, MAC OS X.1 clients

Thanks in advance for the help
