Getting Started with Remote Graphics Software

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows

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:
