If you have just installed Hyper V in Windows 2008 Server and start a new VM and click on it's settings, you may notice that the network adapater does not have any option except 'Not Connected' in the drop down menu.

The solution is simple enough

go into Hyper V Managerand right click on your Server (or in the Actions Pane on the right), choose Virtual network Manager,

click Add, and choose an External, Internal or Private network, give it a name (like Local network only...)

once done click apply, Now go back to your VM and click on settings, Network Adapter, you should now be able to choose the drop down menu and select the new virtual network you just created
