SYMPTOMS
When an application that uses Winsock is running on a Microsoft Windows Server 2003-based computer, you may receive the following Stop error message:

Stop 0x0000007E

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

Note The four parameters in this error message vary.



CAUSE
This problem occurs because the Ancillary Function Driver for the WinSock (Afd.sys) module uses an incorrect parameter to call the IoAllocateIrp function. The ChargeQuota parameter is set to TRUE. If the function is called as a deferred procedure call (DPC), the function can run in the context of the system idle process. In this case, the system tries to free a NULL process object. When the ChargeQuota parameter is set to TRUE in the system idle process context, the system tries to charge the quota to the system idle process. Therefore, the &quot;Stop 0x0000007E&quot; error occurs.
