Disable lock workstation

Is there any way of disabling the lock workstation button on NT4 SP5?  We are using Novell IntranetWare Client 4.11b, and do not have Zen running - the client also bypasses the NT login, using the network login instead.

After reading the doc's it seems that it will work with the Novell client:

If you are using Novell's IntraNetware Client for Windows NT, you have to modify nwginar.dll in %systemroot%\system32\nls\english, because msgina.dll is no longer used. NOLOCKWS detects Novell through the registry entry HLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\GinaDLL.

As taken from the web site http://www.regedit.com is the following article on disabling the lock workstation button.

Disable the Lock Workstation Button (Windows NT)
Add this setting to the registry to stop unauthorized users from locking machines from the Windows NT Security dialog box.

Note: This functionality requires Windows NT Service Pack 4 or higher.

Registry Settings:
Key: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
Value Name: DisableLockWorkstation
Data Type: REG_DWORD
Data: (0 = disabled, 1 = enabled)

Been there, done that, it doesn't work.  I've tried it with values 0 and 1, and neither work.  I was told it didn't work as we didn't have Zenworks.  
Try this one:

This will change MSgina.DLL to disable the button, but As far as I know will the Novell client use NWgina.DLL, so probably it won't work, but you can always try.

This question was awarded, but never cleared due to the JSP-500 errors of that time.  It was "stuck" against userID -1 versus the intended expert whom you awarded.  This corrects the problem and the expert will now receive these points; points verified.
