Live Messenger wont connect - Win7

Error code 8100306

No answers from the Win7 forums so will try here. Get "we cant sign you in
to Windows Live Messenger"

btw: its Windows 7 RC1 64 bit version ( which works great except for this )

Hmm, same here, I dual boot XP Pro and its fine with that. I have tried
disabling the firewall and its still the same, any ideas anyone?

I had the same problem, I am using Windows 7 RC and I was getting the Error code 8100306 from Messenger.

I discovered from another forum, a vista one, that if you disable Auto Tuning it will work, here's how you do it...

You need to run the Command Prompt as Administrator, then type in: netsh interface tcp set global autotuninglevel=disabled

Hope it works for you guys as it worked for me!
