Vista tcp auto tuning

Vista has turned on by default TCP auto tunning that will try and set the most efficient receive window size automatically. The problem is though if all your networking equipment isn’t up to date it will cause Vista to slow to a crawl. To disable auto tuning type the following in a command window as administrator.

netsh interface tcp set global autotuning=disabled

That should return an OK

To check that it is disabled run the following.

netsh interface tcp show global

    I’m sorry, I am completely internet ignorant. I have a new computer running vista on internet explorer 7, was referred to your site because some of my site are so slow to come through. Mainly, new sites and yahoo email, ones that have a lot startup issues. I read your response above however, do not know where to go to get to the admin. command line. Could you please tell me where it is located and I should be able to take it over from there. Thank you.

    Open your start menu -> All Programs -> Accessories Then Right click on Command Line and pick Run as Administrator. You will then be prompted for your password and you should then have a command line shell running as Administrator.
