When VPN enabled, lost DNS and DCO / Event ID 8015, 334 ...

Question

Hello all,
On a Windows Server 2019, when I'm connected on the VPN (IKEV), I lost the connection with local DNS (event ID : 8015).
I lost the communication with my DC (event ID : 334, 5719, 1054).
Of course when I try to connect on shared folder : \nameofcomputer it don't work ... (by IP : yes).
When someone connect on this server it's very long and the VPN disconnect.
NSLookup show that it's the DNS remote who is by default.
So I change the metric, I enter "1" on my network adapter.
NSLookup show :
DNS Request timed out
Default server : Unknow
Address : 192.168.0.1

Thanks in advance for your help.

Answer 1

Hopefully the VPN role is not installed on domain controller?

Answer 2

This server is connected to a VPN server.
It's not the server VPN.
And on the DC there is not a VPN.

Answer 3

Still not a lot to go on and vague but check that the VPN connection box for use default gateway on remote network is checked or unchecked depending on goals.
