Virtual machine no longer connecting to internet

[WillaA]

Hi
My mac crashed earlier today and my Windows 10 virtual machine can no longer access the internet. It was fine before the crash. I ran Windows Network Adaptor diagnostics and it said ""Ethernet" doesn't have a valid IP configuration". This is the full report:

I'm afraid all this means nothing to me so I've no idea if it's any use or not!
I saw a post somewhere saying to change from Shared Network to Bridged Network Default Adaptor but get a message saying "The Default Adaptor network adaptor is not connected to the network".
As I said, I haven't got a clue so any ideas would be greatly appreciated.

Thank you... Willa

Hi

I just realised I didn't have the latest version of Parallels so I've updated it. Now when I start the virtual machine I get an error saying
"Network initialization failed. Your virtual machine will continue working normally but will have no network connection."
I found a YouTube video saying starting Parallels from Terminal fixes the problem so I tried it. A window popped up telling me to install Windows 10?!) which of course I didn't want to do so I quit out of it.
I then started the virtual machine again. Shared Network (recommended) wasn't selected but when I did select it the internet connection started working again.
So I've no idea what resolved the problem but it's working again now .
