We have an internal domain name eastbalt.com and we also have the Internet domain eastbalt.com. Our network is Windows 2000 AD domain using DNS. Our web site is hosted by XO and the name to access it is www.eastbalt.xohost.com. I have been able to setup a forwarder for internet DNS so that if someone puts in www.eastbalt.com it goes to our web site. The problem is from our intranet www.eastbalt.com doesn't resolve. XO told me to put in a cname record so that www.eastbalt.com would go www.eastbalt.xohost.com but this failed to work. They told me that they can't give me an IP address to set up an A record with because of the way they do load balancing. Windows 2000 doesn't seem to be able to do a web forward in its DNS. Is there another way to do this?

I do this all the time. It does work. remove any existing records pointing to www from dns. Then In dns manager, right click your domain(eastbalt.com), select "new alias"

in the alias name field simply put "www"

in the target host put "www.eastbalt.xohost.com."
don't forget the dot at the end of the entry

go to a command prompt
type "ipconfig /flushdns" to clear your local dns cache on your machine.

then ping www.eastbalt.com

I created an alias called crap2 and it worked at my office using the setting above. It resolved to the address www.eastbalt.xohost.com [207.155.252.48]. The ping timedout, but thats because they are blocking ICMP.

H:\>ping crap2.itservicesny.com

Pinging www.eastbalt.xohost.com [207.155.252.48] with 32 bytes of data:

XO was correct, but they may not have been very clear as to the process for making the entry in your DNS.

Just to review, a cname record is the same as an alias record.

Your DNS server should be authoritative for your domain . Using the New Resource Record wizard, in the Alias window, only enter . DNS will automatially append your domain name to this. In the Fully qualified name window, I always enter the actual server name, not another alias (www.eastbalt.xohost.comis an alias). If you can't determine the server name by talking to XO, try the following froma command prompt window: . This command should return the web server name as well as ping statistics.

BTW, assuming that www.eastbalt.com is your real website (and not a name you picked as an example), the reply I just got from a ping was for the server name .

Hope this helps.

I came up with a work around, I had an internal web page automaticly link to the external web page. Problem solved. It would have been a simple fix had the web site had a fixed IP but the solution worked.
