    Hey Rob,

    Thank you for taking the time to post a comment. The Fix it disables TCP auto-tuning by running the "netsh interface tcp set global autotuninglevel=disabled" command. That command is what is called out in each of the articles. The reason for this is having TCP auto-tuning enabled results in multiple symptoms which are individually described in each of the articles.

    Thanks,

    -brian

    Hm, which one should we use?  Are the Fix it downloads all the same in each of these?  They look similar but not identical…

    It would be nice to have direct links to the Fit its in these posts.

    When I initiate windows outlook express 6, I have windows XP by the way. It goes to the email where the heading reads, "Inbox-Outlook Express-Main Idenitity-Backup, then after about a minute on click on the max button, then it goes (Non-Responsive) where it stays and does not work. It just locks itself in and that’s basically it. This started about 2 to 3 days ago and it will not click in.

    Thank you, for any suggestions.

    ALSO, IT TAKES AN AGE TO DOWNLOAD FROM MICROSOFT TO INTERNET EXPLORER – IT SAYS IT SHOULD TAKE ONLY A MINUTE BUT ENDS UP TAKING 4 HOURS AND THEN TIME OUTS.

    PLEASE SUGGEST WAYS TO FIX.

  18. Dorothy says:

    My emails don’t want to come in as in the past. Maybe several up to ten-fifteen will dribble in. They then hang. Can’t stay with computer for hours in waiting on some emails that may never download. When connection is necessary, they start from the beginning all over again. Again, hours wasted. Please help resolve this problem.

  19. Gendou says:

    I ran the Fix It, as well as tried to run the command line commands.

    The change won’t go through.  It just stays at:

    Receive Window Auto-Tuning Level: highlyrestricted

    What can I do?
