i-m new to this forum
i use the latest version of virtual box (4.1.4) but the problem was on earlier versions...
i might say it was from the first time i used it....
i've searched this forum and i didn-t find the solution to the problem...
decription:
host OS: Windows 7 Ultimate X64 (no SP included)
host computer: Fujitsu Siemens AMILO PI 3525 (and more other computers)
guest OS: Windows XP (i also don't think it matters anyway... same problem was with ubuntu or other operating systems)
host internet connection: LAN connection with DHCP enabled from the router or Wi-Fi connection
internet connection works fine until i start virtual box, not a guest machine, but the main application.
the internet connection becomes unavailable,
the icon on the tskbar appeares like this:

i found tke image searching google, it is not my printscreen
i found a temporary solution, as i didn't start virtual box once every 2-3 weeks...
i disabled the network adapter and reenabled it...
the guest OS doesn't need any internet connection or any type of comunication with the host OS...
i need the guest os to test some installers to work with windows XP 32 bit...
any solutions?
