DNS Entry for Website "NW" <interest[ at ]yahhoo.com> 02.07.2007 21:13:27 Our AD domain is say, example.com. We have a hosted website on someone else's network. So that address is example.com, or www.example.com, and outside our network that works fine when typed in a web browser. But within our network the address ahtins.com won't work, not found error. I assume that's because of the domain name being the same as our internatl AD name? What entry in our internal DNS server do I need to make to get it to route correctly? I assume it is an A record, but is there a specific type?

Re: DNS Entry for Website "Steve Gould" <steven.gould at seattle.gov> 02.07.2007 21:47:02 My last company had the same internal domain as our hosted web presence. Was a pain. We used internal DNS to get to our external site by creating an A record of www pointing at the external site. users then need to type www.domain.ext to get there.

Re: DNS Entry for Website "Greg Lindsay [MSFT]" <greglin[ at ]microsoft.com> 02.07.2007 22:09:34 Hi, You could enter an A record on your DNS server for this external IP address. Another option is to delegate authority to the external DNS servers. To do the first, just create a new A record as you described. www IN A <IP address of external web site> To do the second, Create a new delegated subdomain. (Right-click example.com and select New Delegation). When creating the properties of the delegated subdomain, you will be prompted for the name server to delegate to. Type in the IP address(es) of the 3rd-party's DNS servers Advantage of the first is that you get quicker answers to internal DNS queries. Advantage of the second is that you don't need to manually update the IP address of www.example.com if the 3rd party changes it later. -- Greg Lindsay [MSFT] Disclaimer: This posting is provided "AS IS" with no warranties, and confers no rights.

The second option Greg referred to, a delegation, is usually a better idea in many cases, not all. It really depends on whether the Public DNS uses an A record for the name or a CNAME. If it's an A record it should work fine. If it is a CNAME you can create the same CNAME in your internal zone, so long as the public DNS CNAME does _NOT_ point back to the AD Domain name. If the Public DNS uses a CNAME that does this, you cannot use a delegation or a CNAME. -- Best regards, Kevin D.

Re: DNS Entry for Website "Greg Lindsay [MSFT]" <greglin[ at ]microsoft.com> 12.07.2007 21:00:36 Hi JFB, Sorry for the delayed answer. This might be a reverse DNS issue. What is the problem you are having with mail.example.com? Reverse DNS (IP --> host) can only resolve to one host name, even if several are configured in the reverse zone, and mail servers often need reverse DNS for security reasons. Is the IP address of mail.example com the same as www.example.com? Are you using DNS dynamic updates for reverse DNS? Execute a DNS lookup on this IP address and tell me what host name is returned. -- Greg Lindsay [MSFT] Disclaimer: This posting is provided "AS IS" with no warranties, and confers no rights.
