Can you check dns zone if it has entry with same hostname pointing to different ip


I checked my dns.
Got a host record. With correct hostname pouting to correct IP address with timestamp from yesterday date6AM.
Could not find any issues or duplicating ip here.

Are you able to connect with the FQDN of the VM?

then have you tried pinging hostname from client machine from where you are trying RDP connection?

you can clear cache and ensure its resolving to correct ip from client machine
That's usually caused by a time issue. check the time on that VM as it may be too far out to be able to properly authenticate its AD object with the Domain Controller.
(AD hates the time being any more than 5 mins different from the DC)

I don't think time would be an issue here as OP is able to connect to VM with IP address

This is pure DNS caching issue either client side or server side, flushing of both should resolve issue

go into DNS and delete both the hostname as well as the reverse lokup address.  then remote into the server using IP and do a ipconfig /registerdns to reregister the dns name.  on the computer you are remoting FROM do an ipconfig /flushdns.
now ping the server and see if the ip comes back correct.  if it does try and connect using both the short name of the server as well as fqdn.
