SYMPTOMS

You have a computer that is running Windows Server 2003 Service Pack 2 (SP2) and that has more than 32 multichip module processors. However, you can view the cache information for only the first 32 processors on this computer.

For example, if you call the GetLogicalProcessorInformation function to query the processor caches, the cache information for only the first 32 processors is returned.

CAUSE
