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 (Windows XP Professional only)
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
Using the
RGS Diagnostics Tool on Windows on page 75 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
The methods to disable Single Sign-on are described below.
Using the rgadmin tool to disable Single Sign-on
Using the rgadmin tool to disable Single Sign-on is preferred over the manual method for Windows XP
Professional, described next. The rgadmin tool must be used to disable Single Sign-on for Windows
Vista and Windows 7.
Select Disable Single Sign-on and Easy Login and then click Apply.
