If you receive a message such as "...remote connection was denied because the user account is not authorized for remote login.." this is becuase the username you are using to connect to the machine does not have the proper permissions to log into that machine via RDP (Remote Desktop). Permission has to be granted for this to work properly. This is managed by the administrator of the machine you are remoting into.
To test out this theory, what you can do is, from another machine on the same local network, try to RDP into that same machine you are trying to connect to. Use the same login you used with TruGrid. And see if you are able to login. You should see the same error message, since this is due to local permissions on the machine and not related to TruGrid.
If you are the administrator of this machine, please follow these steps to enable remote access.
