Remote Desktop from Windows XP to Windows Server 2008 or Windows Vista 2

The Remote Desktop connection settings for Windows Server 2008, and I believe Windows Vista, includes 3 levels of service:

Don’t allow connections to this computer
Allow connections from computers running any version of Remote Desktop (less secure)
