MS Vista and RDP6.0's Remote Desktop Prompt message

With Windows Vista you always get ugly prompt when connecting to Windows Server 2003 and Windows 2000 Server or XP machines saying:

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?

You can stop this message either by:

1. Add a DWORD registry entry called AuthenticationLevelOverride in the \\HKLM\Software\Microsoft\Terminal Server Client\ key and ensure that its value is set to 0.

•0 This value corresponds to "No authentication.

"•1 This value corresponds to "Require authentication.

"•2 This value corresponds to "Attempt authentication."

2. Click on the advanced tab in the Remote Desktop Connection tool and change the Authentication options to "Always connection, even if authentication fails
