Vista browser issue

I faced a serious problem with Vista sometime last week.Some websites never get loaded in ie or firefox ..or any browser for that matter!

On pondering over some articles in microsoft i came to know that this is due to something called as TCP Scaling.

anyway this can be fixed by disabling tcp scaling altogether or by using a higly restricted mode of operation.

netsh interface tcp set global autotuning=disabled

(Type this in a command prompt with admin access)

you can revert back to normal mode by using:

netsh interface tcp set global autotuning=normal

I noticed that this issue arises when using some routers and firewalls, an update may probably fix this!
