I tried changing the order of the Network Adapter Priority and I'm afraid that hasn't worked either.
No changes to the 3DS Max software or Corona.
I've tried disabling the AVG virus software and also the window firewall and still nothing.
I just tried running the DR Server on the PC with the problem and then clicking on 'Search Lan' and it found itself. Again it showed the following (127.0.0.1 (192.150.14.69)... Not computer name at all.
One more thing, worked for me:
Right click VPN adapter, into ipv4, advanced, unchecked "use as gateway" and change metrik from automatic to 9000.
This should force all connections not to connect to subnet of VPN adapter. Then hope DrServer uses because of this the correct interface.
