In Devices and Printers, the desktop icon shows an exclamation point. I ran troubleshooting and was informed that I need Microsoft teredo tunneling adapter. I have no idea what that is. The Troubleshooter tried to install it but was unsuccessful.
As far as I can tell, my computer operates OK, although I have had some issues with using Skype.
I read that the Zone Alarm firewall may interfere with the installation or operation of the teredo adapter. I no longer have Zone Alarm.
