Hi,
R. Cord here, Independent Expert. Hope you are doing well.
Ensure that the user account "kgara" on the HTPC has the necessary permissions for remote desktop connections. To do this, right-click on the "This PC" icon on the HTPC and select "Properties". Then, click on "Remote settings" and make sure that the "Allow remote connections to this computer" option is enabled.
Try using the full username and domain name when connecting to the HTPC. For example, if the HTPC is on a local network, you can use the following format to log in: "htpc\kgara". If the HTPC is not on a domain, you can use the computer name instead of the domain name.
Make sure that your firewall is not blocking remote desktop connections. You can check this by temporarily disabling the firewall and attempting to connect to the HTPC again.
Try creating a new user account on the HTPC and see if you can connect to it using remote desktop. If you can, then the issue might be related to the original user account.
If none of the above steps work, try resetting the Remote Desktop settings on the HTPC. To do this, open the Registry Editor on the HTPC and navigate to the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server. Then, delete the "WinStations" key and restart the computer.
I hope one of these solutions helps resolve your issue.
