A DNS entry for a server keeps reverting back to its old value in the Forward Lookup Zone. I'm using a microsoft DNS server on a Windows Server 2008 platform. I have a WAN with an AD on each end. The entry gets changed on both when I update one side, but for some reason it keeps going back to the old value (the IP address of the AD/DNS server) after several hours.
Any idea on what might be causing this or how I can troubleshoot?
