CAUSE

This problem occurs because the Llsrpc named pipe is located under the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\NullSession
. As a result, any null session can access the Llsrpc named pipe.

Service Pack 4 replaces the existing data in the
NullSessionPipes
key with the following registry data:
