We are running a web site, with two domain names, accessible ffrom the world but not from internal network.
Windows 2000 domain, with DC running DNS
DNS is all pointed to our DCs, and they are set us successfully to forward DNS to outside servers if needed
Web sites running on Windows 2000 Servers running IIS 5
www.harry.com and www.tom.com (for example) can be found from the outside
inside we have to put in the ip address to get to it
I've tried adding an A record, and also tried adding a new zone for Harry and Tom, but nothing has worked so far
Would adding a CNAME record help?


TIA

Hi slang9,

The first thing you need to do is work out whether this is a DNS or routing issue.

Go to www.dnsstuff.com and put in the address of your webserver.  This will give you the public IP address.

Then go do a command prompt on one of your PCs, and do:
nslookup
www.harry.com

.. this should return you the A record for your webserver.  Check that these are the same.

Assuming they are, then try and connect to the webserver from a command prompt.  Do this:
telnet www.harry.com 80
GET /

(then ENTER a couple of times)
You should get a load of HTML.

If you don't get that far, it's probably a routing/firewall/proxy issue.

Do you have a proxy server (such as ISA server) or firewall on your network?  Is it configured to allow you to access this site?

I hope that this helps - let me know if I can be of any further help.

If your internal network doesn't use the harry.com and tom.com dns suffixes then you need to setup zones for them on your internal DNS servers.  You say you have done this.  Then you need to create A records in those zones with "www" as the name and have them point to the IP addresses.
