DNS

We have a Virtual Machine Server in our Hyper-V, we change the name of the Server but later on we notice that the old Server Name still pinging.

I ping the old Server host name >> reply with the IP

I ping the old Server FQDN name>> no ping result

I ping –a IP Address >> replay with the new Server Name Host Name

I nslookup the old Host Name >> no result

I nslookup the new Host Name >> replay Domain Name & IP Address

Can you help me please?

Regards
