I want to debug the kernel of windows server 2019. My physical host is windows 10. My
VM is windows server 2019(VirtualBox). I followed this video on youtube to complete my 
setup<https://www.youtube.com/watch?v=V7DJ_ptkOpM>.
I got this on my VM which I think it's not the reason I failed

c:\KDNET>.\kdnet.exe 172.26.48.1 51111
Enabling network debugging on Intel(R) PRO/1000 MT Desktop Adapter.
Manage-bde.exe not present.  Bitlocker presumed disabled.

To debug this machine, run the following command on your debugger host machine.
windbg -k net:port=51111,key=1gofrzddjdu9q.2stxhh3p9pieh.114a4fe4c4vr4.16nbo0k9ghw3v

Then reboot this machine by running shutdown -r -t 0 from this command prompt.

I run the command

windbg -k网络：port=51111，key=1gofrzddjdu9q.2stxhh3p9pieh.114a4fe4c4vr4.16nbo0k9ghw3v

The result is this

Using NET for debugging

Failed to initialize IPv4 socket. Error On-2147467259
