How do I install NIC Driver on Hyper-V 2008 Server?

I had to add a Legacy Network Adapter via Hyper-V console for a Windows Server 2008 guest OS to recognize the network (Windows Server 2003 worked with default), if you have the Hyper-V console then:

Right-click virtual machine | Settings | Add Hardware
Select Legacy Network Card, Add

I'm building a win 2008 server to gain access to the Hyper-V MMC tool.  I'll test it out and let you know.  I wasn't sure if it also added it to the underlying Hyper-V Server OS or not.   When I boot the Base Hyper-V it cannot find the network cards.   So I installed an old Intel NIC and it was able to see that one but still not the ones on the Supermicro Server motherboard.  Most likely the chipset is new enough not to have been included in Windows 2008 base.

In reviewing his excellent blogs, his main discussions are about Hypervisor running on top of Windows 2008, not the Direct install of Hyper-V Server directly on the server hardware, which just gives you the console screen.  I couldn't find any articles configuring on Hyper-V Server.

Simple and easy.....  Your solution worked like a charm....
Here's how I did it, the hard way.  But maybe it will help someone else.

1. I built a Lab server, with Windows Deployment Services.
2. Installed Microsoft Deployment Toolkit 2008,

3. Loaded the Hyper-V 2008 Server ISO.
4. Installed all Intel Drivers I will need for old and current builds.
5. Used the Guidelines in Microsoft® Deployment Toolkit 2008
Getting Started Guide, from the Microsoft Deployment Toolkit.
6. Built x64bit Image with LAN Drivers installed.
7. Built a Bootable USB.
8. Booted Server with USB, Did a network install from Windows Deployment Services.
9 Rebooted Server and was able to use NIC Card.

Anyway, like always there are a number of ways to solve problems.  Thanks for finding the quick and easy solution.

Great job finding this.  I ended up getting it done the hard way.  But used your way to rebuild the server quickly.  Thanks again

Your welcome.

Thanks for the "hard way" instructions.
