SYMPTOMS

When you run Windows Management Instrumentation (WMI) queries on a Windows XP-based computer, the following symptoms may occur:

Symptom 1

WMI queries do not return any information for the Win32_DiskDrive class or for the Win32_DiskPartition class when the WMI service runs in the NT AUTHORITY\NetworkService account.

Symptom 2

You use a non-administrator account to run WMI. When you query the Win32_DiskDrive class for the MediaLoaded property or for the Signature property, the MediaLoaded property always returns False, and the Signature property returns Null.
