Ever since the CommNet site for Tech.Ed Australia went live I’ve had trouble logging in – fetching pages seemed to take an unusually long time to happen. I pinged Michael Kleef and he came back with this helpful suggestion, open up a command prompt and type the following:
netsh in tcp set global autotuninglevel=disable
Apparently the routers between you and the CommNet servers have a bit of trouble with Vista’s automatic tuning features and the command above turns them off. Very useful tip!
