SYMPTOMS
A 64-bit version of Windows Server 2003 is running on a computer that has more than 32 processors. When you install a network adapter driver on the computer, Windows Server 2003 may restart unexpectedly after you receive the following Stop error message:

Stop 0x000000D1

DRIVER_IRQL_NOT_LESS_OR_EQUAL

Notes
 * The four parameters in this error message vary, depending on the configuration of the computer.
 * Not all &quot;0x000000D1&quot; Stop errors are caused by this problem.



CAUSE
A network adapter driver must call the NdisMRegisterInterrupt function from the MiniportInitialize function if the network adapter generates interrupts. The NdisMRegisterInterrupt function must run through a loop to initialize the DPC object for each processor.

However, the Network Device Interface Specification (NDIS) miniport interrupt structure limits the number of processors to 32. Therefore, the system generates a Stop error message when the NDIS driver tries to initialize the DPC object for the thirty-third processor.



RESOLUTION
After you apply this hotfix, the NDIS driver supports up to 64 processors.

Note Driver developers may have to rebuild their drivers by using the latest version of the Windows Driver Kit (WDK).
