Answer 1

Check out the sticky thread at the top of this forum, or my blog on how to track down login failures.


 

Answer 2

your article does not address Category 4.  These messages don't have a state.  Any input?

 

Answer 3

I don't believe category 4 has been publicly documented by MS. The other details in the login failure message should provide come clues to the cause if you can post them.
