WMIDiag Version 2.2 Released to Help Diagnose WMI Problems

Windows Management Instrumentation (WMI) is Microsoft's take on WBEM standards for recording PC hardware, PC services, Windows settings, and software information. Anyone that has worked with WMI, particularly for gathering hardware and software inventory using systems management tools like Configuration Manager, know how valuable the collected information can be. They also know that when WMI fails, or becomes corrupted, the entire computer can fail to work.

Fortunately, Microsoft has a tool called WMIDiag to help diagnose problems. A new version, version 2.2, has just been released that fixes some glaring bugs and introduces some new functionality.

After you download and extract WMIDiag, there's a WMIDiag_Readme.doc included that gives you all the command-line parameters and necessary information for using the tool.
