RDP Error – The connection cannot be completed because the remote computer that was reached is not the one you specified. This could be caused by an outdated entry in the DNS cache. Try using the IP address of the computer instead of the name.

Unable to connect to the Remote Desktop. Server operating system is Windows Server 2012 Standard R2. When we try to RDP, we get the below error message:

The connection cannot be completed because the remote computer that was reached is not the one you specified. This could be caused by an outdated entry in the DNS cache. Try using the IP address of the computer instead of the name.

There was two server with same configuration and setting but one of connecting to RDP with AD authentication whereas the other was not working. One was physical and the other was virtual hosted on an ESX host.
RDP on physical was good and the issue was with the virtual host. It was confirmed that the issue was due to time latency.
Therefore, this issue was due to the time difference between the virtual machine and the NTP server set on an ESX host.
This issue was later fixed by synchronizing the server time with the ESX host.

Note:
If you do not wish to have auto sync, disable the Windows Time service or block the outbound port 123 on your local firewall.

Thanks,
