Server 2008 connected to network but saying its not install hyperv is installed

I recently did windows updates and it installed an update for a 'Realtek PCIe GBE Family Controller'.  I also uninstalled Hyper-V.  Ever since then, my server is connected but its showing the network adapter with a red x.  When I open cmd and installed Hyper-V with servermangecmd, it all of a sudden starts to work.  Hyper-V is already installed and I keep installing it over and over and that fixes the issue.  I can't even open up the network sharing center until I use the install hyperv command.  Any ideas?

Disregard about the Hyper-V thing, that isn't the case.  Its something to do with that update I installed but I can't find the driver update that I installed from Microsoft updates in the recently installed updates ....
You can open Device Manager, open properties of the network card, and in Drive tab, you can perform Roll Back Driver. This will remove your driver update.
