NOTE: The first parameter may differ, but the fourth parameter will be thesame on a uniprocessor system.
This problem has been identified in the Afd.sys driver. For instance, theNwLink Nwlnkspx.sys driver makes a reference to close a connection, and AFDdereferences the connection and sets the counter to zero. However, incertain instances Afd.sys does not handle the dereference properly andAfd.sys later tries to dereference the connection object again. This causesthe machine to stop.
