I have had this really irritating error come about in the last week where I can't sign in to messenger. Error 81000306 indicates that the problem could be caused by a firewall, proxy settings, DNS cache. I followed all Microsoft's instructions but to no avail and I have ALLOWED msnmsgr.exe in ZoneAlarm, so the lack of info they're giving me is getting on my nerves. I even uninstalled, ran Registry cleaner and reinstalled but still nothing. Can anyone help?

Its a stupid thing with MSN live Wellcome screen

If u have Zonealarm Go to:

1. control Center
2. Privacy
3. Disable ad blocking, and cookie Control

And it should Work It did for me....

Later on U can play with custom settings if u have the nervs

I didnt :D

for people that think they tried it all and still get the error 81000306:

I had no firewall
latest messenger installed
all services were running ok
logged in from website
tried to run all dlls mentioned on forums
messenger worked but live messenger didn't log in...

then I noticed that messenger didn't connect to .net messenger service
(tools/options/conections) and UPnP wasn't checked as ok...
I turned on UPnP to try connecting thro NAT

I turned it on, and all my troubles were gone.

I feel stupid now.. should have tried that first...

Thanks guys, the problem has long been solved. Thanks again:D

Hi guys

I'm using Vista but cannot find a solution to this problem. I don't have messenger to amend the options. Only live messenger which I cannot access.

:dead:
