Network Card issue with Windows Server 2008 R2 on Dell D630 and D820

I’ve setup Hyper-V Server R2 and then Windows Server 2008 R2. The installation phase went very smoothly but when the real thing had to configured it failed. The system was unable to load the network card driver unlike desktops Windows 7 or XP.

It make sense that a server system is not supposed to be a WiFi connected system and is supposed to be a stationary server system with network cable connected to it to a network switch, sounds pretty ok. So what was the problem then, after the installation I didn’t see any Ethernet Card except the Wireless network card when which was never been able to make connection to my internet router.

I spent heck of time but all the time it was a failure, I saw some very strange error while configuring the Ethernet but none of effort worked.  There was one very small stupid thing which really doesn’t make sense. And it was a Power problem, the laptop was on battery and by default Intel network card disabled automatically when there is no AC power connected or the laptop is on battery. ..it sucks it really sucks… but on the other side a server is always connected to AC. No idea whom to blame but I’d still suggest that please don’t try to save the power at this level.

So NEVER EVER AND EVER DISCONNECT THE BATTERY CHARGER WHILE INSTALLING ANY SERVER OS ON A LAPTOP.
