This post provides the possible fixes for Windows Live Messenger or MSN error code 81000306 or 800B0001. If you ever encounter this dilemma, which is quite common nowadays, don’t be panic. Try out each of the following fixes and you might find one that works. Symptom: Sorry, we were unable to sign you in to the .NET Messenger Service at this time. Please try again later. Error code: 81000306. Difficulty: Moderate.

Fix: Registry Error

Most of the time a MSN connection error is caused by random registry errors. I would recommend you to download and run Registry Easy to automatically fix your PC’s registry errors.

If you want to fix the registry manually, here’s how:

Re-register Softpub.dll Mssip32.dll Initpki.dll. This solution is indeed the most effective fix among all the others. Click on Windows Start button, click Run (in Windows XP or older), type the following code into the open field, or into the search box immediate after clicking Windows Start button (Windows 7 or Vista), and then press enter:

regsvr32 Softpub.dll Mssip32.dll Initpki.dll

Fix: Are your PC really connected to the internet?

Double confirm that your computer is connected to the internet. Just by looking at the Google homepage isn’t enough to prove that you’re actually online. Visit the following sites to verify that you’re connected to the internet and check that Windows Live Service status is stable and online.

Messenger service status

If the .NET messenger service status is showing a service issue, you’ll have to wait for an hour or two and try to sign in again later.

Also, please make sure that your system clock time shown on the bottom right corner of your desktop is correct and accurate. This could be the cause of any connection error.

Fix: Disable the Auto Tuning Networking feature

Click on Windows Start button -> All Programs -> Accessories -> Command Prompt (Windows 7 or Vista: right click -> run as administrator). Type the following command and then press enter:

netsh interface tcp set global autotuninglevel=disabled

This command disables the Window Auto Tuning feature. Try to sign in to your Windows Live Messenger account now and see if it works. If you are still not able to sign into Windows Live Messenger, we recommend you to re-enable the Window Auto Tuning feature. Open the command prompt again, type the following command and then press enter:

netsh interface tcp set global autotuninglevel=normal

ipconfig /flushdns

This will flush the local DNS cache in your Windows.

1. Open Internet Explorer
2. Click Tools from the menu bar, then click Internet Options.
3. Go to Connection tab, click Lan Settings button.
4. Under Proxy Server section, UNCHECK Use a proxy server for your LAN.

Fix: Driver failure

In some rare cases, MSN connection error can be caused by driver failure or missing driver. I would recommend you to download and run Driver Robot to automatically search and install drivers for your computer. Otherwise, you’ll have to manually seek for the driver that causes the error, then reinstall or update the broken driver.

If all the above methods don’t fix your problem, try ErrorFix which does a great job in repairing Windows Error.
