Windows 2003 Scalable Networking pack and its possible effects on Exchange

You can actually see what connections are offloaded by using the netstat -t command.

This -t switch is only available if the networking pack is installed on a server.

An offloaded network connection can be in one of the following states:

In Host - the network connection is being handled by the host CPU

Offloading - the network connection is in the process of being transferred to the offload target

Uploading - the network connection is in the process of being transferred back to the host CPU

Offloaded - the network connection is being handled by the offload target.


Or you can use the netsh command which I prefer without having to reboot:

Netsh int ip set chimney DISABLED
