we have two servers that reside in our dmz, this two servers have the dns ip address from our isp. inside our network we need to access those servers through port 80. all the servers have windows 2003 with latest updates. how can I add an entry on the domain dns server inside our network to get to those servers by entering the website on those server instead of entering the ip address on the addres bar in the browser.
the ip address on those servers are 192.168.2.240 and 192.168.2.241, the websites are access.elpcars.com and home.elpcars.com respectivelly.
any comments will be appreciated. thank you.

If these two servers are in the same domain as your private network, you can add a DNS record for each host to the zone for your domain manually.  If they are on a separate domain, you will need to create a separate zone for them and then add the records there.

Hope this helps!

Yes - like I said, it all depends if they are on the same domain or not.  If your current DNS zone is for elpcars.com, then all you need to do is add a host record for the host name "access" and point it to the correct IP address.  If you've never added a DNS record manually, it's easy.  Open the DNS management console and point it to the primary DNS server (or any DNS server if you are running in AD-integrated mode).  Expand the view to open your forward lookup zone.  Click on the zone name folder, then right-click and select New Host (A).  Enter the host name and IP address in the fields provided.  This will enable you to get to those servers by name.

You could allow them to self-register, but you'd have to open some ports on your router between your private network and the DMZ, which you probably would not want to do.

thanks for the comments, it worked for servers that are on the same domain. but, the servers that im trying to resolve the name to ip address are not in the same domain. the servers that are working are in the domain max.local and two servers that are on the dmz have different domains two have elpcars.com and one has elptech.com when created the record for those servers, it was pointing to an external ip address that clients use to access the websites on those servers. I clear the dns cache but did the same thing. I dont know if the record I created was correct because it creaded subfolders. thanks for the comments.

If the servers in your DMZ are on different domains, there are a couple of ways to resolve this.  If these IP addresses are public and are hosted by your ISP's DNS servers, you could simply set forwarders for these two domains to point to those external DNS servers.  If the IP addresses you want to point to are private,  you would have to create separate zones on your DNS server(s) for the two other domains, and then add manual records to those zones.  Is this what you did?
