81000306 Error - Windows Live Messenger in Windows Vista

Anyone else getting this error trying to run Windows Live Messenger (I've tried v8.0 and 8.1) under Windows Vista? If you are here is how to fix it:

The key is to disable "Auto-Tuning" of the packets that Windows Vista does by default.

- Click Start, All Programs
- Accesories
- Right-Click Command Prompt
- Click Run As Administrator
- Type the following: netsh int tcp set global autotuninglevel=disabled
- Press Enter
- Close Command Prompt Window
- Restart your computer

This worked for me, and seems to have greatly speeded up my networking in the process - I'm now back to transfering files over the network at higher speeds again, another side-effect of Vista trying to be too clever.

Lots of other users have also reported this error, particularly when using a Netgear DG834/DG834G Router, and another possible cause is that the router firmware needs to be rolled back to version 3.01.29 (Thanks Microsoft TechNet

Thanks very much, your solution worked without rebooting pc. Running vista home premium, recent upgrade, through Netgear DG834G wireless router.

Many thanks for this, I was going absolutely nuts trying to solve this problem and had tried many "solutions" on the web but this is only one that worked. I have a DG834G router as well so doubt it is any coincidence!
