I've got a brand new (out of the box today) Windows 7 desktop with a curious issue. I had an issue installing Microsoft Office 2013. I restarted the computer and after doing so, the computer was offline and unable to connect to the internet. The Local Area Connection icon is missing from the Network Connections.
The NIC is listed in device manager and everything appears to look normal. I have uninstalled the device, restarted the computer (device reinstalled correctly) and I've still got the same problem. When I do an ipconfig, I do see Local Area Connection listed and I get an IP address of 169.254.x.x
Other computers are on the network are fine.
