To disable Single Sign-on without the use of the rgadmin tool, delete or rename the
value of the GinaDLL registry key. If there is no other custom GINA module on the
system, simply removing the GinaDLL key definition from the registry disables Single
Sign-on. The GinaDLL key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
NT\CurrentVersion\Winlogon\GinaDll
is removed through the use of regedit, the Windows Registry Editor. Be certain to
actually remove the key by selecting the GinaDLL key in regedit and select the
Delete
entry in the Edit menu. Once the key is deleted, it no longer shows up as a
key in the WinLogon subkey. When the system reboots, the default GINA module,
msgina.dll,
will be loaded by the WinLogon.exe process.
If there is a custom GINA DLL module on the system and it replaces the default
msgina.dll
, change the value of the GinaDLL value from hprgina.dll to the name
of the custom GINA module. To change the value of the GinaDLL key, select the
GinaDLL
key in regedit and then select the Modify entry in the Edit menu. A dialog
box appears allowing the value of the key to be changed. Type the name of the
custom GINA module in the "Value data:" area. Confirm that the custom GINA
module entered actually exists on the system in C:\WINDOWS\system32. When the
system reboots the custom GINA module is loaded by the WinLogon.exe process.
WARNING : If the value of the GinaDLL key contains the name of a custom GINA DLL,
and the file does not exist in C:\WINDOWS\system32, the system will not start
correctly upon the next reboot. The system will then require a complete re-
installation of the operating system.
