Set Default Authentication Logon Method to SmartCard
So how do you set the default logon method for Windows 2008 Server Remote Desktop Services users to use Smart Card / CAC authentication?
Open Notepad, copy and paste the following and save as a .reg file or edit registry directly:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI]
"LastLoggedOnProvider"="{8bf9a910-a8ff-457f-999f-a5ca10b4a885}"
