NT\CurrentVersion\Winlogon\GinaDll
4. Set the value of the GinaDll key to the text "hprgina.dll". Confirm the
spelling before closing.
5. Add the GinaDllMode registry key if does not already exist. This can be done
through the use of regedit as well. Create the key as type RGS_SZ (a string
type). The full path of the key is
HKEY_LOCAL_MACHINE\Software\Hewlett-Packard\Remote Graphics
Sender\GinaDllMode
6. Set the value of the GinaDllMode key to the text "HprSso". Confirm the
spelling before closing.
7. Restart the system. The hprgina.dll will be loaded by WinLogon when
started.
WARNING: If the hprgina.dll does not exist in C:\WINDOWS\system32, do
not perform steps three and four. Doing so puts the system in a state that
requires a complete re-installation of the operating system.
If the GinaDLL key does not currently exist in the registry then Microsoft's default
GINA DLL (msgina.dll) is currently loaded by WinLogon. Adding the GinaDLL
registry key and setting its value to hprgina.dll tells WinLogon to load the
hprgina.dll instead of the default msgina.dll.
If the GinaDllMode key does not exist in the registry, or if the key does not contain
the text "HprSso", then RGS Single Sign-on will be enabled by default.
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 Diagnostic Tool programmatically
detects if this local security policy is set correctly. See the RGS Diagnostic Tool
section for more information.
Note: Creating the GinaDLL registry key disables Window's "Fast User Switching" and
"Welcome Screen" features.
Uninstalling and Disabling Single Sign-on
There are two methods used to disable Single Sign-on:
1. Using the rgadmin Tool:
The RGS Rgadmin Tool contains command-line options to disable RGS Single Sign-
on. This method is preferred over the manual method.
2. Manual Method:
