How to use ADPlus to troubleshoot "hangs" and "crashes"

ADPlus is a tool from Microsoft Product Support Services (PSS) that can troubleshoot any process or application that stops responding (hangs) or fails (crashes). Frequently, you can use ADPlus (ADPlus.vbs) as a replacement tool for the Microsoft Internet Information Server (IIS) Exception Monitor (6.1/7.1) and User Mode Process Dump. These are two separate tools that PSS frequently uses to isolate what causes a process to stop responding (hang) or quit unexpectedly (crash) in a Microsoft Windows DNA environment.
