The following java project contains the java source code and java examples used for how to validate and verify a winnt user and password using java and vbs. This code can be used to validate a WinNT User and Password on Windows 2000/XP/NT machine using a java class. I think its very easy to follow and very helpful to use. It worked for me. Probably someone out there may find it helpful too.
