Passwords can be tested programmatically. Open a reference to the VI in question and wire it to an invoke node with the Set Lock state method. Now you can write a code that will try different passwords. Write a password generator that generates all possible combinations. If you know the password must be between 3-5 letters etc...restrict the generator accordingly. If you ever use real words you can let the generator use a dictionary.
I think there was such a password finder on http://www.citeng.com/ at one time but could not find it again (could remember wrong), perhaps someone else has is in their user library still though.
The number of possible combinations per second is a bit limited so if the password is much more than 4 characters and you need to run
a brute force attack it could be too tough.
