I changed the IP address of a server. I have another server that needs to connect to it for backups. When I ping the server that I changed the IP using the FQDN it finds the previous IP and the ping fails. If I ping the new IP it finds it.
If I ping the same server from another server using the FQDN it finds the correct IP.
I've done ipconfig /flushdns twice.
So from the server that cannot ping the FQDN what is wrong and how do I fix it.
