Internal DNS issue?

I run a web server on my network. I've noticed that when I access a website
hosted on that server from within my network, it takes the pages much longer
to load than when I access the website from outside of the network.

I read somewhere something that led me to believe that this might be a DNS
configuration issue. Is that likely to be true? If so, can someone point
me to a KB or something that will tell me how to tweak the DNS to solve that
problem?

Thanks

Is the Web server behind NAT?

Do you host your own public DNS zones?
If yes, and you only have one DNS server there is nothing you can do, you
need two DNS servers, minimum.
If no, create forward lookup zones using the FQDN of the site, e.g.
www.website1.com then in the zone create one new host, leave the name field
blank and give it the internal IP address of the web server.

It would be easier for us to help if you described
you DNS setup <grin>

If you don't have AD, you can ignore (most of) the
references to "DYNAMIC" below probably, but
you really must make sure you clients use only your
internal DNS if you wish to maintain reliable access
to internal resource servers (e.g., you web server.)

For INTERNAL DNS (especially for AD):

1) Dynamic for the zone supporting AD
2) All internal DNS clients NIC\IP properties must specify SOLELY
that internal, dynamic DNS server (set.)
3) DCs and even DNS servers are DNS clients too -- see #2

Restart NetLogon on any DC if you change any of the above that
affects a DC.

Ensure that DNS zones/domains are fully replicated to all DNS
servers for that (internal) zone/domain.
