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 This could be caused by an outdated entry in the DNS cache.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:

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,

I recently got an issue with one of the Citrix servers. None was able to take RDP and while checking the event log through the ILO, I found the above error. I found that the issue was with the terminal service certification. The below mentioned steps were performed to resolve the issue.

1. Make sure that the terminal server registry has been successfully backed up.
2. Start Registry Editor.
3. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TermService\Parameters
4. On the Registry menu, click Export Registry File.
5. Type exported-parameters in the File name box, and then click Save.

NOTE: If you have to restore this registry subkey in the future, double-click the Exported-parameters.reg file that you saved in this step.
6. Under the Parameters registry subkey, right-click each of the following values, click Delete, and then click Yes to confirm the deletion:
Certificate
X509 Certificate
X509 Certificate ID
7. Quit Registry Editor, and then restart the server.
