I have two Windows Server 2008 R2 servers. both are domain controllers, one is a public web server with dns installed, the other is an exchange
server (2007) with dns installed, my problem is that no matter what I try, the DNS record for that server keep updating to the servers local ip (because the exchange is behind a nat). Ive had this issue before and was able to resolve it, however for some reason
what worked in the past is not working now.
Im seriously about to pull my hair out over this issue because we basically have no email until this is functional.
Heres what Ive tried:
- Disabling DNS Registration on Adapter for Exchange
- Adding numerous Registry keys that were supposed to stop this
- Disabled dynamic updates on DNS domain
- Manually changed IP in DNS (keeps changing back)
The public web server, has a public IP address. The exchange server is behind a NAT with the server ports forwarded (using MXtoolbox.com, they show as forwarded and communicating)
