Hi,<br />
<br />
We recently moved our Exchange Server to a different subnet in the same company. We changed the IP address of the Exchange Server (Exchange 2007, Server 2008) and pointed it at the new DNS servers. Our inbound and outbound mail are working properly but there is a problem. The DNS on the mailserver will not update. When I try to ping the mail server from itself by name it is coming up with the OLD IP address. I checked the DNS settings on both DNS servers and they have the new IP address, when I ping the mailserver by name from them it resolves correctly. All other computers and servers are resolving name to IP correctly except for the mail server. Is there some sort of internal setting I need to change in Exchange as well?? I am stuck and not sure why the Exchange server is the only one that won't &nbsp;pull the new DNS setttings. Any ideas? I flushed the DNS and rebooted twice, no changes.

Exchange Server not updating DNS settings after IP address change

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
