Can you try to ping 69.57.142.26, 66.35.250.150, 216.239.37.99, 216.239.57.99 or 216.239.39.99? If you get a reply, try to enter them into your browser. If that works, try to get the DNS server address under windows and enter it in /etc/resolv.conf > If you know something better than formatting my pc, > please tell me where should I begin... > > One last thing... > Other than those of recovered vi sessions, I can > read some unusual mails about system occurances etc.. > when I logged in as a root(but I dont know what they > really mean) > Looking forward to your kindness, > -jay :=( Hendrik
