i have hyperV server running on which , i have just created a windows server 2008 virtual machine, where in that virtual machine network adapter is not detected. how to solve this problem.
@kaustubh93 Try installing a LEGACY network adapter. For machines as old as Win2K8 Server, the default network adapters may not work (did not for me), but installing a Legacy adapter did the trick.
This fix (using a Legacy adapter) worked this evening on a Windows 10 Pro installation running Hyper-V Client. I'd installed a Windows 7 Pro VM, but it wouldn't access the Internet via the Virtual Switch (external). Once I installed the legacy NIC, I had Internet access from within the VM.
Windows 2008 R2 is essentially Windows 7 anyway, so this solution is likely to work for you as well.
