Configure and troubleshoot Windows Management Instrumentation

23 July 2000 by Snakefoot | Comment » | Trackback Off
Windows Management Instrumentation (WMI) will fail to start or operate properly if the WMI repository is corrupt. Depending on what version of Windows, there are different ways to repair/rebuild/reset the WMI repository:
  • Windows Vista/2008:

    winmgmt /verifyrepository
    winmgmt /salvagerepository

  • Windows XP (Requires atleast SP2):

    rundll32 wbemupgd, UpgradeRepository

  • Windows 2003 (Requires atleast SP1):

    rundll32 wbemupgd, RepairWMISetup

  • Other versions (Note it will reset the ICS and ICF configuration):
    1. winmgmt /clearadap
    2. winmgmt /kill
    3. winmgmt /unregserver
    4. winmgmt /regserver
    5. winmgmt /resyncperf
    6. net stop winmgmt
    7. del %windir%\system32\Wbem\Repository\*.* /s
    8. net start winmgmt
    9. %windir%\system32\wbem\wbemtest.exe

Note if for some obscure reason wanting to disable the WMI service, then WinMgmt.exe will complain, this can be solved by running these commands before disabling:

winmgmt /clearadap
winmgmt /kill
winmgmt /unregserver

To see all parameters for WinMgmt.exe :

winmgmt /?

You are a genius! I’ve been hunting for days to find this fix and the first thing I’ve tried on your site did it. Absolutely the best!

After searching for 2 hours I found your info. W2k8 Svr St. So simple winmgmt /salvagerepository fixed my WMI and GPO event log related issues. ThanX

Should add this for Win 7:

winmgmt /resetrepository

I was close to jumping out of the window(s ™). But my XP SP2 revived WMI after following your instructions

Thanks a lot.

You are worth your weight in gold. This fixed the following for me:
* programs failing to install with an error of failing to connect to Windows Installer
* unable to connect to WMI Tester
* When checking Dependencies tab in Services had some error about service dependencies interface class not registered.

I also found this script useful as found here:

@echo on
cd /d c:\temp
if not exist %windir%\system32\wbem goto TryInstall
cd /d %windir%\system32\wbem
net stop winmgmt
winmgmt /kill
if exist Rep_bak rd Rep_bak /s /q
rename Repository Rep_bak
for %%i in (*.dll) do regsvr32 -s %%i
for %%i in (*.mof,*.mfl) do Mofcomp %%1
net start winmgmt
goto end

if /I (%1) == (wbemcntl.exe) goto End
if /I (%1) == (mofcomp.exe) goto End
%1 /RegServer

if not exist wmicore.exe goto End
wmicore /s
net start winmgmt

This script basically re-registers all *.dll, *.mof and *.mfl files related to the service

However I needed to change this line from:
for %%i in (*.mof,*.mfl) do Mofcomp %%1
for %%i in (*.mof,*.mfl) do Mofcomp %%i
^ Changed the number 1 to a letter i.

Thank you! Repair/rebuild/reset the WMI repository works. Now my Windows 7 is not freezen anymore.

Took me all day to find you, but so worth it.

I just cut and pasted this - rundll32 wbemupgd, UpgradeRepository - into Run box and WMI was restored in XP.

Thank you so much!
