Regression - networking broken after upgrade to 5.0.0 and also subsequent updates

[oldium]

This worked with 4.3.x, but the problem started with upgrade to 5.0.0 from 4.3.28, but continues with every minor update - after installation, start-up of every virtual machine reports:

Cannot connect to the network interface '\DEVICE\{C5EF3C32-2A5B-4649-B646-5A5D3A3BB319}'. The virtual network card will appear to work but the guest will not be able to connect. Please choose a different network in the network settings.

The problem is with VirtualBox Host-Only Ethernet Adapter.

I tried to restart computer after update, but still the same problem.

Removing and re-adding VirtualBox Host-Only Ethernet Adapter from VirtualBox menu does not help.

The Device Manager with "Show hidden devices" option enabled shows that "VirtualBox Host-Only Ethernet Adapter - Deterministic Network Enhancer Miniport" has exclamation mark with detail "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)".

Please note that I am using 192.168.150.0/24 network for VirtualBox Host-Only adapter (IP 192.168.150.2, mask 255.255.255.0, DHCP 192.168.150.3, dynamic address from 192.168.150.100 to 192.168.150.199), because the default address 192.168.56.0/24 is my regular network.

When I uninstall and install VirtualBox, the "VirtualBox Host-Only Ethernet Adapter - Deterministic Network Enhancer Miniport" device still reports the same problem. I need to uninstall VirtualBox first, reboot and install VirtualBox afterwards in order to get the networking up-and-running again (after changing the IP and DHCP of the Host-Only adapter from VirtualBox menu).

This is reproducible with every update, starting from 5.0.0.

I am using Windows 7.

Do you need more info from me?

Just to be precise, my network is 192.168.56.0 with mask 255.255.254.0 and gw 192.168.56.254.
