SYMPTOMS

On a computer that is running Windows Server 2008 or Windows Vista, you may receive the following Stop error:
STOP 0x000000D1 (<parameter1>, <parameter2>, <parameter3>, <parameter4>) DRIVER_IRQL_NOT_LESS_OR_EQUAL
Note This Stop error may also be caused by other problems.

This problem usually occurs when the Netbt.sys driver is loaded and unloaded frequently.

CAUSE

When the Netbt.sys driver handles a timer expiry completion routine, the Netbt.sys driver does not obtain a global spin lock. This behavior may cause a timing issue. When the timing issue occurs, two threads in the Netbt.sys driver concurrently access a NetBIOS over TCP/IP (NetBT) timer structure. Then one of the two threads frees a call back pointer. However, the other thread tries to call back a routine by using the call back pointer that has already been freed. Therefore, the Stop error occurs.

RESOLUTION
