I made an earlier post about telling if the newer advanced tcp functionality included since sp2 in 2003 server, vista, w7, 2008r2, etc was working or not. The one that I neglected to include was whether or not TCP offloading was really working or not.
All you need to do is run this command while traffic is taking place:
netstat –nt
The output will look like this:
On the right hand side you can see that my connections on the example computer are in the host and not offloaded.
