I doubt the account you are using has WMI permissions. Verify using these instructions http://technet.microsoft.com/en-us/library/cc787533(WS.10).aspx On Fri, Jan 29, 2010 at 12:43 PM, aki <aki275@googlemail.com> wrote:

I had also removed the filter and it still behaved the same. I am 100000000% sure that the code is perfect, just like the C# snippet has vindicated. Anyway, I run the C# application and got the message below:
Unhandled Exception: System.UnauthorizedAccessException at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 e rrorCode, IntPtr errorInfo) at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.Mo<http://system.management.managementobjectcollection.managementobjectenumerator.mo/> veNext() at WMISample.MyWMIQuery.Main()
Still looks like something to do with permissions... but which user needs to have permission to what?? That's my question. My account has full permissions on wscript.exe, cscript.exe and even scrrun.dll
@Simon, try these and check permissions ( from run ) :
Wmimgmt.msc ( and right click on properties. Click security tab and check root )
or
Wbemtest.exe
Your WMI log files are at : %SystemRoot%\system32\wbem\logs
Beyound this, as a learner am out of ideas. poolay! :-)
