I am running a Windows 7 64 Ultimate host and a Windows XP guest. I had had a host only network interface configured, and was using it successfully with this guest. That interface is now gone following upgrade, and when I try to recreate it, there is an error. I was previously having problems previously with DHCP (or lack thereof) on the host-only network interface. Now I can't seem to use it at all. I will attach a JPG with the error dialog. The gist is an assertion that the access was denied to create the interface ""COM RC = E_ACCESSDENIED (0x80070005). The error dialog shows up immediately and then I see Win 7 pop up an administrator dialog indicating that Virtualbox would like to make changes to the computer, but by this point it seems Virtualbox has already given up and nothing ever gets added. I have tried rebooting. I also tried starting the Virtualbox application with administrator privileges, but the same error dialog appears (but there is no pop-up from Win 7 asking permission to make changes).
