SYMPTOMS
A multiprocessor computer running Windows NT and using TCP/IP protocol may give the following STOP error message when an application tries to close a socket:

Stop 0X0000000A(0x0000000a,0x00000028,0x00000002,0xf24cc2be)

NOTE: The fourth parameter within parenthesis is computer-specific, and will most likely vary from computer to computer.
