match the string originally discovered in the registry key GinaDLL. Confirm
the spelling before closing.

3. Restart the system.

When the RGS hprgina.dll is loaded by WinLogon, hprgina loads the chained GINA
DLL foogina.dll

. The hprgina module then chains all GINA requests to the

foogina

module.

If the custom foogina.dll is also a chaining GINA module, foogina, in turn, chains
itself to the msgina module. Three GINA DLLs will be loaded as part of the
WinLogon.exe

process: 1) hprgina.dll, 2) foogina.dll, and 3) msgina.dll.

Setting the Local Security Policy

The local security policy "Interactive logon: Do not require CTRL-ALT-DEL" must be
disabled to support Easy Login. 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 Easy Login

There are two methods used to disable RGS Easy Login.

1. Using rgadmin Tool:

The RGS Rgadmin Tool contains command-line options to disable RGS Easy Login.
This method is preferred over the manual method.

2. Manual Method:

To disable Easy Login without the use of the rgadmin tool, delete or rename the
value of the GinaDLL registry key. If there is no other custom GINA module on the
system, simply removing the GinaDLL key definition from the registry disables Easy
Login. The GinaDLL key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
NT\CurrentVersion\Winlogon\GinaDll

is removed through the use of regedit, the Windows Registry Editor. Be certain 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 no longer shows 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 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
