Any suggestions on how to force my DC (which is also my primary internal DNS server) to grab the latest public DNS entries for my websites?
I recently changed a public IP address for one of our websites. 6 hours later, externally, a ping returns the correct, new address. However, internally, a ping still returns the old address. Our firewall (on the perimeter of our network, obviously) returns the correct, new address when pinging the site, so it seems very likely that the issue is with my DC... no?
I've checked my forward lookup zones for any manual entries that might conflict, and there aren't any. I've run ipconfig /flushdns on the DC (and backup DC), as well as the client workstations. Any ideas? Thanks!
