Summary—If the GinaDLL key does not currently exist in the registry, Microsoft's default GINA DLL
(msgina.dll) is loaded by WinLogon. Adding the GinaDLL registry key, and setting its value to
hprgina.dll, informs WinLogon to load hprgina.dll instead of the default msgina.dll.
Setting the local security policy
The local security policy "Interactive logon: Do not require CTRL-ALT-DEL" must be disabled to support Single Sign-
on. This can be set in the Windows "Local Security Settings" under "Security Options." The RGS Diagnostics Tool
programmatically detects if this local security policy is set correctly. See the section
Tool on Windows" for information on this tool.
NOTE: Creating the GinaDLL registry key disables Window's "Fast User Switching" and "Welcome Screen"
features.
Disabling Single Sign-on
There are two methods to disable Single Sign-on:
1. Using the rgadmin tool to disable Single Sign-on
The rgadmin tool shown in Figure 3-13 can be used to disable Single Sign-on. Using the rgadmin tool to
disable Single Sign-on is preferred over the manual method, described next.
2. Manually disabling Single Sign-on
To disable Single Sign-on without using the rgadmin tool, delete or rename the value of the GinaDLL registry
key. If there is no other custom GINA module on the computer, simply removing the GinaDLL key definition from
the registry entry below disables Single Sign-on.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\GinaDLL
CAUTION: 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 computer will not start correctly after the next reboot. The computer will
then require a complete re-installation of the operating system.
The GinaDLL key is removed using regedit, the Windows Registry Editor. Be sure 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
