WMI Security Problems

Hello,

I've done a small web application that uses WMI wrapper
(System.Management) and everything works fine on Cassini's development
web server from VS2005, while retrieving the device id and model from
the Win32_DiskDrive object.

Under IIS native ASP.NET server I'm experiencing security problems
since wbem logs says that an error has occured
(IOCTL_..._GETDRIVELAYOUT).
I'm not using impersonate option because the IE and the server will
run on the same machine and I gave all permissions possible to the
wwwroot folder and I'm noticing that all works fine except the WMI
functionality (i.e. retrieving the model and the physical drive name
given the drive letter).

What can I do to fix this problem and get the WMI to work ok with my
web application?

Thanks.

I found that if I do a query over Win32_DiskDrive or Win32_LogicalDisk
the results are good, but over Win32_DiskPartition returns no results
at all (on IIS ASP.NET server). Maybe security reasons? What can I do
to fix this problem?
