How can i Login In my C# application using windows Login details? or export my window

[ThandoSiphambo]

I have an application that is connected in to a sql database, instead of connecting to the database, i want it to use the windows usernames and passwords to login into my application.

windows usernames and passwords are stored in this location:

c:\windows\syst em32\config\sam

But how can i use this as my database or export usernames and passwords to sql.....

Windows doesn't store the password, it only stores the hash. Not the same thing.

If we're talking about SQL Server, then it has native Windows authentication. It can authenticate against the current credentials of whoever is logged in.
