IntroductionWhat is WMI?

◦Wikipedia: “WMI is Microsoft's implementation of the Web-Based Enterprise Management (WBEM) and Common Information Model (CIM) standards from the Distributed Management Task Force (DMTF).

◦SMS 2.0 MOC: “WMI does for management software what printer drivers did for printing”

◦Me: “ The registry on steroids.”

Troubleshoot WMI Wmidiag Repair

◦ XP SP2+ rundll32 wbemupgd, UpgradeRepository

◦ Vista and above (Needs to be Run as administrator) winmgmt  /salvagerepository

◦ Windows server 2003 rundll32 wbemupgd, RepairWMISetup

Re-register wmi components◦ cd /d %windir%\system32\wbem ◦ for %i in (*.dll) do RegSvr32 -s %i ◦ for %i in (*.exe) do %i /RegServer

Rebuild repository as a last resort (Might kill other applications)◦ Net stop winmgmt

◦ Ren %windir%\System32\Wbem\Repository %windir%\System32\Wbem\Repository_Bad

◦ Net start winmgmt

SccmAutoDocWhat is SccmAutodoc?

1. My source for getting to know WMI in ConfigMgr2. A program that, based on WMI queries

automatically documents your site settings Where can I get SccmAutodoc?

◦ SccmAutodoc 1.126 is currently in beta and can be downloaded from http://www.scug.be/media

Is SccmAutodoc freeware?◦ SccmAutodoc will become moderately priced

software once it leaves the beta stages, hopefully somewhere near the end of this year.
