I Recently went from Windows Server 2003 to Windows Server 2008 R2. After the installation windows was nagging me about no drivers found for my network controller. On the intel download site it says the adapter is supported out of the box so there isn't a driver for it.
conclusion: I ended up with a useless server adapter with support up to windows vista but not for windows 7 or server 2008 r2 :/
Is there any workaround for this ?
In earlier versions of Windows* the server adapter used the same driver as the desktop adapter. You could try forcing the adapter to use the driver for the Intel(R) PRO/1000 T Desktop adapter. I do not know for sure, but I think that driver will work.
