Windows Server: Hotfix Available for STOP 0x000000D1 Blue-Screen on Multiprocessor Windows Machine



Article Summary: This article provides information on an available hotfix for a 0x000000D1 bugcheck caused by tcpip.sys on a multiprocessor Windows machine.



The 0xD1 bugcheck code is a very common one in all versions of Windows. It translates to DRIVER_IRQL_NOT_LESS_OR_EQUAL, indicating that a driver has attempted to access memory in an improper manner. Third-party drivers are common culprits, but built-in Windows drivers can also be to blame for this stopcode.

Microsoft released a hotfix in December 2013 to address a known cause of this issue in the built-in tcpip.sys driver on a multiprocessor computer. The issue is caused by a race condition in the driver that causes a crash if duplicate TCP segments are received on multiple processors.

The issue is described in Microsoft Knowledgebase article KB2905412, which contains a link to the hotfix for all versions from Windows Vista to Windows Server 2012.
