I have two computers on one i had internet trhrought lan cable now i connect t to the other comp and give ip settings and still i cant access net on it . but the settings show everything is allright

This should be in Firewalls and Networks. Also are you using a router?

no roouter i turned off the firewal and checked not workin

what are you using to connect the 2 computers?

Make sure your network drivers are updated. I had the same problem a while back and all I needed was to update the drivers. :P
