Figure 3-14 Using rgadmin to disable Single Sign-on (Windows Vista and Windows 7) Manually disabling Single Sign-on (Windows XP Professional only) 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. 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 deleted, it will no longer show 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 if 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 in C:\WINDOWS\system32. When the computer restarts, the custom GINA module will be loaded by the WinLogon.exe process. Installing RGS on Windows 65
