Re: DNS or IIS problem with Win2003 server

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hello Dave,

In your DNS zone create an A record named "www" wihtout the quotes and use the LAN ip address from the web server.

Your configuration is a bad decision, a domain controller should NOT run any additional appplication like Exchange, SQL or IIS. It should do its basic job, AD, DNS and GC, if no other server is available DHCP.

This all belongs to security reason and performance. Also demoting a server with SQL, Exchange will have additional configuration tasks. Even if you use a firewall, a webserver connecting to the internet should be in a DMZ and again NOT on a DC.

We have a Win2003 server running active directory and IIS. We have a
calendaring website on the server that is accessed at
calendar.mydomain.org both inside our firewall and externally. It is
the only website running on our server and it is the default website.
Our firewall also performs NAT since we are using private addresses
internally.

We have brought up a website at a hosting service that is our
www.mydomain.com site and it works fine from outside our facility.
I've set up two A records in our DNS server on the Win2003 machine,
one for calendar.mydomain.com pointing to the Win2003 server and one
for www.mydomian.com pointing to our external website address. When I
do a ping against these two websites I get replies from the correct
addresses.

It's a different story with browsers. When I try to go to the
calendar.mydomain.com from inside our firewall everything works fine,
but when I try to go to www.mydomain.com I get the
calendar.mydomain.com page in my browser (and the url displayed gets
changed to http://mydomain.com)

So, ping is working correctly but my browsers (I've tried both IE and
Firefox) still end up with the wrong page for the www.mydomain.com
site. What's going on here? It seems like DNS is working since my
pings work, but why are my browsers getting redirected?
