Windows Vista – Windows Live Messenger error 81000306

Continuing the Windows Vista voyage…I came upon a problem with Windows Live Messenger. WLM wouldn’t let me sign in, error 81000306 was reported. Asking WLM to “Troubleshoot” the problem didn’t reveal any issues nor did it offer any solutions.

So, hunting around I found this post that worked for me. Running netsh int tcp set global autotuninglevel=disabled in a command prompt as Administrator – interesting fix, must make some time to look that one up. There’s more about autotuninglevel here. Stephen Lamb has produced some good information over here (originally via Alan)
