Hi!
I have a serious problem installing vista business. During installation expanding files 21%
(directly after first reboot) I get the following error message: "Windows cannot
install required files. Network problems may be preventing Windows from
accessing the file. Make sure the computer is connected to the network and
restart the installation. Error code: 0x80070005"

I've tried following without any succes:
*running Windows Vista Upgrade Advisor, said there should be n problem.
*staying connected to network (and internet) during installation.
