The Apple Ethernet Update 2.0 consists of version 2.4.3 of the Apple Ethernet extension. This improves AppleShare connections in high-traffic network environments. When you use certain Mac OS 9 applications while connected to AppleShare volumes, disconnections can occur. You may see "TickleTimeout" disconnect messages in the Mac OS X Server 10 Apple File Service access log. The Apple Ethernet Extension 2.4.3 prevents these disconnections from occurring.
