Guest Adam V. Posted December 7, 2007 Posted December 7, 2007 Hello: I have a customer who had another consultant install Active Directory and Exchange on the same server. They used, as the domain name, BDL.local and the full computer name: bdas01.BDL.local. They've had some issues with Exchange, and I recently noticed they never setup a PTR for reverse DNS. I contacted their ISP to do this, but they need a valid mail server name. As far as I can tell, the mail server (which is the same server as the domain controller) is named bdas01.BDL.local. Unfortunately, their public domain name is bennettdesign.com. I would think the IP address of their mail server would need to resolve to a server name that has bennettdesign.com in it in a reverse DNS lookup. Any recommendations on how to handle this? Do I need to change the server name? Do I need to change the Active Directory domain name to bennettdesign.local? Thanks, Adam V.
Guest Anthony Posted December 7, 2007 Posted December 7, 2007 Re: Is it necessary to rename a domain controller for reverse dns Hi Adam, No, you don't need to do either of those. Whoever is hosting the dns zone for bennettdesign.com needs to set up an MX record for your mail server. The name can be whatever you like, but mail.bennettdesign.com sounds good. Then in your firewall you need to do NAT so that your internal Exchange Server has an external address, which corresponds to the address of the MX record. Then your ISP, who is providing you with the IP addresses, needs to set up that name in their Reverse zone. So when AOL say "who is xxx.xxx.xxx.xxx?" they look up the ISP's reverse zone and find its you. There is no relationship at all betwen the actual server name, the Active Directory name, and the internet domain name. Hope that helps, Anthony, http://www.airdesk.com "Adam V." <AdamV@discussions.microsoft.com> wrote in message news:CFF6FEB1-F7DE-4E00-9337-78BB49142373@microsoft.com... > Hello: I have a customer who had another consultant install Active > Directory > and Exchange on the same server.
