SYMPTOMS
Your Microsoft Windows NT Server 4.0-based computer may stop unexpectedly (crash), and you may receive a &quot;STOP 0x00000041&quot; stop error message.



CAUSE
This problem occurs because of a memory leak in TCP/IP on your Windows NT 4.0 server. A memory leak in TCP/IP may occur if a computer that is running Microsoft Windows 95, Windows 98, or Windows 98 Second Edition repeatedly sends a Control Bit TCP packet from the same IP address. This behavior is known as a network packet storm.

TCP's Network Driver Interface Specification (NDIS) packet pools are designed to maintain a small size so that they do not use too much of the non-paged memory. However, during the network packet storm, the NDIS packet pools on your Windows NT Server grow very large. When the NDIS packet pools grow to a certain size, they stop maintaining a limit on the non-paged memory that they use. The packet pools use most of the non-paged pool memory. Therefore, the computer stops unexpectedly.
