To fix this issue you have to disable the auto-tuning feature.
(1)Click Start--> All Programs--> Accessories-->Right-click the entry Command Prompt, and choose Run as administrator
(2)Now type the following line in the command prompt, and press Enter:
netsh interface tcp set global autotuninglevel=disabled
Now retry to sign in to Messenger.
If you get the same error, re-enable the auto-tuning feature by repeating the above steps with the following line instead:
netsh interface tcp set global autotuninglevel=normal
