Identifying the Problem
WMI is one of those services that simply work. Most people never have to troubleshoot WMI; in fact, many network administrators do not even know WMI exists, or that their sophisticated monitoring and tracking application relies heavily upon the services of WMI. For many, the only time they even begin to learn anything at all about WMI is when a critical application "all of a sudden quits." This is, unfortunately, the wrong time to begin to learn about WMI and more importantly how to troubleshoot WMI.

The other 10 percent are really strange, esoteric, downright exotic problems. We will therefore focus on the four issues that cause 90 percent of the problems.
