Again I got Windows Live Messenger Error Code 81000306 in my Windows Vista. Which means I could not connect to the Windows Live Messenger server. There was this fix that I did some many months ago, and it still works.
- Click start
- Type: cmd (but don’t hit Enter)
- Right-click cmd.exe when it appears under Applications
- Click Run As Administrator
- Type the following: netsh int tcp set global autotuninglevel=disabled
- Press enter
It should work without rebooting. I must have turned on the TCP during one of the Windows update or something. But this didn’t help me on my office new Ricoh Aficio 2027 Multifunction copier printer scanner. Though I could send print jobs to it, but the scan jobs would not send to my PC. Still trying to figure that one out.
