The My-T-Soft Logon Utilities checks the existence of GinaDLL value in the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\WinLogon key to determine if the logon utilities are enabled or not. You can refer to the help / technical detail in the Help portion of the logon utilities for additional details. Here is a quick overview of what goes on:
When enabled, the Logon Utilities sets the GinaDLL=%windir%\MYTSOFT\IMGGINA2.DLL value in the WinLogon key (full path above). Windows uses this to change the default logon interface - My-T-Soft uses this to display the keyboard during logon. This will only work if the entry matches what the Logon Utilities creates in the GinaDLL value. You can use RegEdit to monitor what it is before an reboot, and what it is after a reboot - this may give you a clue as to what may be modifying it (i.e. if the GinaDLL is something else, then you can refer to the replacement value). If the logon utilities does not update this value (permissions / rights to the registry), then it will also behave as you describe. The key would be to modify it via the Logon Utilities, and use RegEdit to see what is actually going on with that key / GinaDLL value. You can also update it manually to see if it reacts differently.
Finally, we are aware of other software that modifies this entry (Novell Netware Client, and older Cisco wireless network adapters, for example). We do provide a "chaining" mechanism for the Novell GINA (see Logon Utilities help), and have worked with Cisco to ensure that their software interfaces within windows at the Network Protocol layer (MPR layer). Once you identify who/what is modifying this, you may want to see if there are updates / support notes.
