I installed a Q-Tec Firewire Card, and it changed my settings in Win XP so I couldnt
get on the internet. Intranet was still working.
(Automatic private address -instead of DHCP)
Finally I found all the places in Regedit where there was a Ipautoconfig and I erased
the value 162.xxx.xxx.xxx) also the subnetmasks. After a reset all was well again.
