wmi repository corrupt

i use wmi to create processes on a remote machine. however, I found one of machine stops responding my wmi command. It turns out that the wmi repository on that machine is corrupted. The symptom is that you cannot use wbemtest to connect to root\cimv2. You may use following to rebuild the repository.

1. Disable and stop the WMI service.

     sc config winmgmt start= disabled

     net stop winmgmt

2. Run the following commands.

     Winmgmt /salvagerepository %windir%\System32\wbem      (I noticed that you have run this command, but I would suggest that you try it again)

     Winmgmt /resetrepository %windir%\System32\wbem

4. Re-enable the WMI service and then reboot the server to see how it goes.

     sc config winmgmt start= auto

generate kernel dump file on windows

Sometimes, it's very strange to see that the windows 2008 server fail to generate kernel dump file even you enable it. After a little while digging, I found that the root cause it because the paging file is disabled. Thus, you need to enable paging file to generate kernel dump file.
