VirtualBox Network Adapter Not Installed as ENDPOINT on Windows Host
|Reported by:||FineWolf||Owned by:|
Currently, the installer doesn't install the VirtualBox Network adapter as an NDIS_DEVICE_TYPE_ENDPOINT(1). The end-result of this is Vista/Win7's Network & Sharing Center shows an additional network as Unknown, bumps all other networks to public mode, and causes trouble with everything network related on a machine (extremely visible on computers with Wireless LAN such as laptops).
The solution as described in the forums ( http://forums.virtualbox.org/viewtopic.php?f=6&t=9429&start=0#p85653) is to simply manually identify the sun_vboxnetadp as an NDIS_DEVICE_TYPE_ENDPOINT by creating the NdisDeviceType (there should be an asterisk before that) key and setting it to 1.
The sun_vboxnetadp being an ENDPOINT by definition, this should be done by the installer out of the box. It's been an issue persisting for various versions now and should be fixed ASAP.
