SYMPTOMS
In Microsoft Windows Server 2003, you receive a &quot;Stop 0x000000D1&quot; error message. The error message resembles the following:

Stop 0x000000D1 (977e6fde, 00000002, 00000001, ba045c43)

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)

An attempt was made to access a pageable (or completely invalid) address at an interrupt request level (IRQL) that is too high. This is usually caused by drivers using improper addresses.

If kernel debugger is available get stack backtrace.

Arguments:

Arg1: 977e6fde, memory referenced

Arg2: 00000002, IRQL

Arg3: 00000001, value 0 = read operation, 1 = write operation

Arg4: ba045c43, address which referenced memory

After you receive this Stop error message, the computer restarts automatically.



CAUSE
This problem occurs because a race condition occurs in a module of the Tcpip.sys file. When the race condition occurs, the module tries to access an object that is already freed. Therefore, the module accesses an invalid memory address.
