I am writing a Windows NT service that needs to popup the standard “user logon” dialog box.
I know in advance that the workstation is locked. The basic idea is to emulate a “secure attention sequence”, i.e. CTRL+ALT+DEL. The user will be responsible for fill the login credentials. I would like to know, for example, if I can call a function on Winlogon.exe , or the standard Gina (msgina.dll) , for example.
The premises are:
1. I can’t replace the GINA
2. I need a code that works inside a service (I am using Microsoft Visual C++).
