If suddenly you wonder why your computer doesn't connect to your network anymore and you can't figure out what the heck is going on, it could be a possible TCP/IP Stack corruption. I spent three evenings on this problem on a shared (me and the fiance) laptop. In 2 minutes after reading the posts below, the error was fixed. I am putting this in my must remember in case weird s### happens box. :)

Symptoms: In a command line, during ipconfig /release and ipconfig /renew.
An error occurred while renewing interface ‘Internet’: An operation was attempted on something that is not a socket.
From a command line, issuing a ping command (to a local network address) shows: "Pinging * with 32 bytes of data destination host unreachable(repeated 4 times)Ping statistics for *:etc etc"In the above msg, in place of the * it shows a different non-alphanumeric character (such as a triangle); whereas on a properly working machine, it shows in those locations the IP address it was pinging. Something is wrong...
One of the tools to fix the problem. Another tool available here.
