Windows Vista Remote Desktop 6 Authentication Prompt
When you use Remote Desktop on your Vista computer, you get this prompt:
Remote Desktop cannot verify the identity of the computer you want to connect to. This problem can occur if:
1) The remote computer is running a version of Windows that is earlier than Windows Vista.
2) The remote computer is configured to support only the RDP security layer.
Contact your network administrator or the owner of the remote computer for assistance.
Do you want to connect anyway?
Of course, you can click yes and continue but this is quite annoying.
What it means:
Windows Vista and the yet to be released Windows Server 2008 both support TLS authentication which uses certificates to validate the identity of the remote computer. Windows XP and Server 2003 don’t support this and never will. You don’t care. You don’t need this anyway.
What you should do:
Click the Advanced Tab in your RDP settings
Under Authentication Options, select Always connect, even if authentication fails
Go back to the General Tab and save your changes.
