I have a worse problem, I installed two DGE-530T NICs on the same computer running Microsoft Hyper-V Server 2008 R2. Use pnputil utility to install the Windows 2008 64 bit drivers, but got only one of the DGE-530T working. The other, at first time, worked (ipconfig showed it with IP got from DHCP), but when I tried to assign it to a virtual network adapter through Hyper-V Manager, simply went away, it does not appear anymore as an available NIC or through ipconfig.
The other is still working and I assigned it with no problem. I would like that the second DGE-530T works, but I ran out of options, do not know how to do it. Both NICs are pretty new, never used before.
Any help, please?
Thanks
James
