This happened all of the sudden, I restarted the system and BOOM!

After noticing the icon with the Exclamation mark at the system tray, there was nothing wrong with communication but the reporting is really messed up!

I've uninstalled the NIC driver and reinstalled it, reviewed services permission and if they are running but still no lucky here...

It's Win 8.1 Pro x64, the computer is member of a domain and I'm surely online, otherwise I could not be writing this post! ;)

Any help would be greatly appreciated!

Hello Marcio S, A,

Have you made any change before this issue?
Do you have other computers in the same domain have the similar issue?

As this issue happen all if a sudden, you can restore Windows back to an earlier point in time, called a restore point.
For more information, please take a look at the following article.

did you upgrade your Windows 8.1 from XP?

Check OP reply:

A follow up for anyone reading this. My problem was apparently caused by upgrading from XP and usinging the keep files and settings option. Though there are very limited items brought over from an XP installation, something buried somewhere disabled the network connections.

To fix this, Windows 8 has a new feature called reset. This basically does setup all over again if you choose the erase files option. You have to enter the product key again when you do this. It is a clean installation.  I had to update the graphic card drivers, add Media Center back in, install the HD Homerun Prime software, run the cable advisor, do TV setup and finally have it working as I had planned.

I suggest try same procedure (if you upgrade from XP to Windows 8.1), choose reset and reinstall back all the drivers

After many attempts of repairing the problem following knowledge base from MS, and third-party support solutions without success, we gave up and restored the system from a backup, about 2 weeks earlier when there was no problem...

Thank you all for the imput but the solution to this matter may never be known, at least in this case!
