Description

Disables offloading of processor tasks to the network adapter. Offloading is designed to optimize performance of Windows 2000.

Network Driver Interface Specification (NDIS) 5.0 lets TCP take full advantage of intelligence in network adapters by letting the adapter do some of the tasks that the processor normally performs. Offloading these tasks to the network adapter leaves the processor free for tasks that only it can perform.

In Windows 2000, TCP supports offloading of Internet Protocol security (IPSec) encryption to network adapters with encryption hardware. It also supports offloading of TCP checksum calculations on headers and data to capable network adapters.
