Thread: DNS again....
February 21st, 2002, 12:01 PM #1
Ok, i posted a while ago about not being able to get to my companys public web page ,that is being hosted by our ISP, from inside our private network.
Before i was not sure when the problem started because we were able to get to it before. But, i have not figured out that when we switched from a novell 4.2 network to win2k a few months ago, is when the problem started.
Now, using the command line i have used tracert, and NSLookup to try to figure out where IE was being directed when a user inputs our web address to get to our public web page. It seems that everyone is being directed to our DC/DNS server. When the IP for the web page is put in, boom, right to the page with no problems (DSL hookup).
Our private domain name is the same as the public. There our no problems getting to the website from outside our network. In the DNS setup i have the 2 forwarders setup to look at our ISPs two DNS servers.
Does having the same private name as our public domain name usually cause problems like this? Or was our DNS server setup wrong? I was not the one to setup our DNS or DC when we did the switch. Do i need to change our private domain name? What about deleting and remaking our foreward lookup zone for DNS? We are running AD which is dependent on DNS and if i delete our only foreward lookup zone, what reprocusions would that have?
Hmmmm......i have alot of questions but i have gone through the microsoft KB looking for answers and have not come up with much. Thank you for any help or advice.

internally, when you try to ping the website (ie: www.mycomany.com) by name do you get the correct IP address returned?

No, i get, unknow host message. One thing i did fail to mention....i did try adding the ip and site name to my host file on my desktop and then i did have no problems. So that is why i am pointing the finger at my DNS server.

Sounds like you just need to create the record on your DNS server for the webserver.

That is what i was thinking but i dont know how to do that. Can ya point me in the right direction?

I don't have a W2K DNS server in front of me right now. It is basically opening up the DNS mmc, create an A record with the name www.mycompany.com (in the Forward lookup zone I think), then fill in the IP address. You may have to stop and then restart DNS services for that to take affect.

That did not work. I could not make a record with a "." in it. It would not let me put in the "dot" after www or the website name. If i do a tracert on the IP address of the site, i get a mach of the IP address and the site name. hmmmmm......

Try just putting in the "www" for the host name, the rest should come from your domain anway.

DVNT is correct in the second posting. You create a "host" record with the name of "WWW" and also place a check mark in the box for "create pointer" as well. You will need to create this record under the "domain" that it is going to be for if your servers have multiple domains on it.
If you look at the attached pic it might shed some light on the subject

That did it!
Thank you DVNT1 and Mntsnow. So, is this a normal setup procedure if your private domain is going to have the same name as your public? It does make sense to me now and i know that this will be a lesson i will not forget.

Yes. If both your "private" side and "public" side are going to share the domain names you need to create the desired DNS entries to properly point to the required servers as needed.
