Now the important question is how did your DHCP client get set to disabled, it doesn't just happen on its own... I would still run a full scan with your Antivirus and Malwarebytes
That was going to be my very next question - how in the world would something like that get changed. I am ashamed to admit that my antivirus is not current... How do I run malwarebytes?
Malwarebytes found 3 items. I removed them and rebooted.
When in the process of troubleshooting this, I disabled my firewall. I received an error message when I did so, but apparently it did turn it off. Now when I click on "Use recommended settings" I receive "Windows firewall can't change some of your settings. Error code 0x8007042c."
You may want to run the Microsoft Fix It tool located here: http://support.microsoft.com/kb/2530126 Just incase there are other issues with the Firewall that aren't apparent, it may find and resolve them automatically.
I just discovered that I have no sound. "This computer cannot play audio because the Windows Audio Service is not enabled. Would you like to enable Windows Audio Service?". When I click YES I get "No audio devices are installed."
