    I want to use windows authentication in my vb.net application rather than validating against Database. Is there any possiblitiies or APIs that allows me to use Windows authentication?

    I have user id and passoword text boxes. Once user entered the userid and password, it should validate again Windows authentication.

    Any help would be highly appreciated

    It doesn't quite work that way. You use the My.User to determine if they are already logged in or not in a particular group. That way you let windows handle authentication and your app simply checks to make sure if they are authenticated and at what level of trust.

    Something like this:

    Public Class Form1

 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  If Not My.User.IsAuthenticated Then
   MessageBox.Show("Sorry you must be logged to use this program")
   Me.Dispose()
  End If

  'or

  If My.User.IsInRole(ApplicationServices.BuiltInRole.Guest) Then
   MessageBox.Show("Sorry Guest are not allowed to use this program")
   Me.Dispose()
  End If
 End Sub
End Class
