SYMPTOMS
In Microsoft Windows Server 2003, you perform a Windows Management Instrumentation (WMI) query against a Windows Driver Model (WDM) kernel provider. If this query uses an embedded class, you may experience either of the following symptoms:
 * You receive bad data in response to the query.
 * You receive an error message when you execute the query.



CAUSE
The problem may occur when WMI uses an incorrect offset. For example, WMI may use a 32-bit offset when the embedded class requires a 64-bit offset.

Technical support for x64-based versions of Microsoft Windows
If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
