I'm the administrator of a Windows 2000 Small Business Server which my company uses for way too many things. It has our email server, dns server, file server, and so on. And when we deployed a J2EE app running JBoss, it got nomitated for the task. Just the other day when I was working with our app, it quit responding. It took me a number of hours to figure out what the problem was, so I figured I'd archive the solution here.
