    If we disables anonymous access, windows launch an alert box of user name and password for authentication. Can anyone plz tell me that 1- Which mechanism is used by windows to launch this alert or message box 2- Which dll file is called by windows operating system during this authentication mechanism? Please help me...

      It wants you to use Windows Authentication by default if you turn off anonymous access. This is the same thing that happens when you log in to the network. It talks to the domain controller and authenticates you for the network. It (sometimes) asks you again if you try to connect to a server without anonymous access, particularly through a browser. I do not know which DLLs are responsible for this. You can't hack them anyway. That would be bad...

          The dialog is created - in XP and later - by the CredUIPromptForCredentials function.

            You need to be a little more specific. Are you trying to access a network share, or a website? If it's a network share, then you'll be looking at SSPI challenge-response authentication, using NTLM or Kerberos, and LSASS.exe as the file that's handling it. If it's a website, it could be attempting to use NTLM/Kerberos, or it could be using basic authentication. These two work in very different ways - Googling for IIS authentication methods will help you here.

              Is this what it has come down to? Any question about how the system works inside is automatically deemed to be rooted in malicious intentions? I recently posted a question about how the OS uses the BIOS, and people started assuming I was a virus writer.

                No, I'm just saying you'd probably break the system if you tried to change it even slightly. Because Windows doesn't like it... not because it's morally wrong or something.

                  What? Did I miss something? What is the meaning of that?

                    GINA is the name of the subsystem used by XP and previous versions for logging the user onto the system. Do an MSDN search for GINA and you'll see. :)
