3-1-2-1 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 Diagnostics Tool programmatically detects if this local security policy is set correctly. See the section "Using the RGS Diagnostics Tool on Windows" for more information. NOTE: Creating the GinaDLL registry key disables Window's "Fast User Switching" and "Welcome Screen" features. Disabling Easy Login There are two methods to disable Easy Login: 1. Using the rgadmin tool to disable Easy Login The rgadmin tool shown in Figure 3-15 can be used to disable Easy Login. Using the rgadmin tool to disable Easy Login is preferred over the manual method, described next. 2. Manually disabling Easy Login To disable Easy Login 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 system, simply removing the GinaDLL key definition from the registry entry below disables Easy Login. 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 system will not start correctly upon the next reboot. The system will then require a complete re-installation of the operating system. The 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 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 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 on the system in C:\WINDOWS\system32. When the system reboots the custom GINA module is loaded by the WinLogon.exe process. Installing RGS 63

Installing RGS 63

3-1-2-1 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 Diagnostics Tool

programmatically detects if this local security policy is set correctly. See the section “

Using the RGS Diagnostics

Tool on Windows

“ for more information.

NOTE:

Creating the

GinaDLL

registry key disables Window's "Fast User Switching" and "Welcome Screen"

features.

Disabling Easy Login

There are two methods to disable Easy Login:

1. Using the

rgadmin

tool to disable Easy Login

The

rgadmin

tool shown in Figure 3-15 can be used to disable Easy Login. Using the

rgadmin

tool to disable

Easy Login is preferred over the manual method, described next.

2. Manually disabling Easy Login

To disable Easy Login 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 system, simply removing the

GinaDLL

key definition from the

registry entry below disables Easy Login.

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

The

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 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

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 on the system in

C:\WINDOWS\system32

. When the system reboots the custom GINA module is loaded by the

WinLogon.exe

process.

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 system will not start correctly upon the next reboot. The system will then

require a complete re-installation of the operating system.
