Sometimes its become critical to troubleshoot the WMI related issues
We can use the Os Inbuilt tool called WBEMTEST.exe for troubleshooting the basic issues. More issues are because of missing objects or corrupt of WMI classes
Step 1:On a Windows Server 2008 or Windows 7 machine, verify whether WMI has a problem or not by running the following command:
winmgmt /verifyrepository
check the reponse is: WMI repository is consistent
Consistent:
If you see the response is consistent, then go ahead and use the WBEMTEST
to see if you are query the Objects
WBEMTEST:
If you’re experiencing problems with an event log feed it can sometimes be useful to try WBEMTEST, Microsoft’s built-in WMI test program. To use WBEMTEST on the LOCAL computer:
1. Type in WBEMTEST into the Run box off the Start menu to start up the WMI Tester app.
Or
C:WindowsSystem32WbemWBEMTEST.exe
2. Tick “Enable all privileges”, then click “Connect…”
3. Change Namespace to rootcimv2, leave everything else as-is and press “Connect”
Click on the Enum Class Button
Select Recursive Radio Button and click Ok button
Check if you are getting adequate number of Objects: On my machine I got 1204 Objects
OR
Back on the main screen, press “Query”
Enter the following query, and press “Apply” SELECT * FROM Win32_NTLogEvent WHERE Logfile=’security’
Inconsistent:
If you get as inconsistent response, then run the Salvage
If there is something wrong with WMI on the machine, the command will return a message stating that the “repository is inconsistent.” If WMI is fine, it will say the repository is consistent.
If the repository is inconsistent, run the following command to repair it:
winmgmt /salvagerepository
There are scenrios, where you see hard time in working with commands
Issue:- WMIC commands are not running specific command Share
Cause:- MOF files were corrupted.
Resolution:- We first check in the Wbemtest and found that we are only able to see 54 Objects. We then ran the mof commands from
Cd C:WindowsSystem32Wbem
for /f %s in (‘dir /b *.mof *.mfl’) do mofcomp %s
This re-compiled the mof files and now we are able to use all the switches in WMIC.
