W10 guest running on Fedora 23 in Virtualbox.Ok, I did something stupid. I deleted the Winsock entries in my registry without saving them first. Yes, cynical laughter is appropriate. However, after doing some frantic research, I found the following to restore things.Running powershell as administrator ...netsh winsock reset catalogThat command returned no errors, and the Winsock and Winsock2 entries reappeared in my registry.Then ...netsh int ipv4 resetResetting interface, OK!Resetting Unicast Address, OK!Resetting Neighbor, OK!Resetting Path, OK!Resetting , failed.Access is denied.Resetting , OK!Restart the computer to complete this actionThis last command, however, returned an "access denied" error. The last two "Resetting" lines look as though there is an attempt to reset nothing, because there is a blank in front of the comma. Needless to say, restarting the guest did not solve the problem, which is that I have no connectivity. I tried deleting the network device in device manager and rescanning, then deleting the net device and restarting, but that didn't help either.Any help would be greatly appreciated.
