Ticket #6225 (closed defect: fixed)
Upgrade from 3.1.2 to 3.1.4 breakes network connectivity permanently - even after a subsequent downgrade

I have just been asked by Perryg in the forum to open a ticket as my issue is reproducable.
After an upgrade from 3.1.2 to 3.1.4 on a Windows XP SP3 32bit host, network connectivity is completely broken. In particular the host-only network interface has not been installed properly. In Windows device manager it appears as unknown device and under the VirtualBox GUI there is no host-only device at all. Without host-only interface I cannot start any of my VirtualBox guests anymore.
So I try to dowgrade to 3.1.2 performing the following steps:
- Uninstall 3.1.4 and reboot
- Re-install 3.1.2 and reboot
- Windows device manager shows deactivated host-only network device.
Activation of host-only interface in Windows device manager turns host-only interface into an unknown device
I repeat this upgrade and downgrade procedure for several times with allways the same result.
It's worth to be mentioned that I have tried to manually create the host-only interface using the VirtualBox GUI for serveral times. Every time I get the "Failed to create host-only interface" message and in Windows device manager an additional unknown host-only device appears.
Currently I do not know what logfiles or whatever information could be helpful. So please give me feedback how I can give you further information to solve this issue.
