Messenger problems: Solving Messenger error code 81000306 at sign-in

Some of you have problems while trying to sign in to Messenger, receiving error code 81000306. Let’s take a look at the solution.

  • Open the Messenger status website at . If you see a green check there, that means that the Messenger service is running, and you can continue with the next step. If the service is not running properly, check back later, until it is running. Continue with the next step then.
  • Delete the Windows Live Messenger proxy settings.
    • Start Messenger.
    • Open the menu next to your display name, and click Options.
    • In the left column, choose Connection.
    • At Connection settings, click the button Advanced settings.
    • Delete the SOCKS entries.
    • Click OK, then again OK.
    • After you have deleted the proxy settings, retry to sign in to Messenger. If it still doesn’t work, continue with the next step.

  • If you are using Windows Vista, disable the auto-tuning feature.
    • Click Start, All Programs, Accessories.
    • Right-click the entry Command Prompt, and choose Run as administrator.
    • When Windows prompts for your consent, click Continue.
    • Now enter the following line in the command prompt, and press Enter:
      netsh interface tcp set global autotuninglevel=disabled
    • Note: using this command, you are disabling the Windows auto-tuning feature.
    • Now retry to sign in to Messenger.
    • If it still doesn’t work, re-enable the auto-tuning feature by repeating the preceding steps, yet typing this line instead:
      netsh interface tcp set global autotuninglevel=normal
  • If you are using Windows Vista and a router (e.g. made by Linksys, Netgear, D-Link) to connect to the Internet, visit your manufacturer’s website to check for updates to your router’s firmware.

  1. tnx.. this fixed my (netsh interface tcp set global autotuninglevel=disabled) live messenger in win7 connection problem. 🙂

  2. Many thanks! Problem with live messenger on Vista now resolved thanks to netsh interface tcp set global autotuninglevel=disabled.

  3. quero saber que problema afetou o Windows Live Messenger. Porque quando tento entrar não consigo, pois aparece um aviso que diz sobre algum erro e também fala desse relatório de erros. Como eu faço para resolver este problema?

  4. how did I get that problem anyway ?
    it is to difficult to solve that problem with this manual,
    and I refuse to adjust any vista settings just to solve a
    problem I didn’t inflict in the first place.
    my other MSN account works fine so why this problem and the sudden need
    to make dangerous changes in my settings ?
    who ensures me after these changes something else
    would not be influenced or damaged ?

  5. My boyfriend can log onto his messenger account on my computer just fine but I can’t log onto mine, just getting this error code. Tried the fix mentioned here and problem still persists.
