ICS Problems

Posted on 2006-03-24

In my local area network there are four computers.  One computer which is the "master" computer on the network, shares files, it's printer and the internet to the other three computers on the network.

Today, I had to reinstall Windows XP on one of the computers on the network (not the master computer).  Since then, I've been unable to get ICS to work properly.  Whenever any of the computers on the network attempt to connect, there is a long pause before an IP address is assigned, and the IP address which is assigned is of an incorrect range and not 192.168.0.x.

To my knowledge, all settings are correct on the machine which had a reinstall of XP Home.  Additionally, none of the previously working settings have changed on the other three machines.  I still can't seem to get to the bottom of this though, even with the firewall on each machine turned off.

I would really appreciate any suggestions anyone may have to help me fix this problem.

    What is the incorrect IP "range" ? 169.254.x.x ?  
    If so it means your computers are unable to connect to t a DHCP server, the ICS computer. Either the DHCP SERVER service is not running on the 'main' computer or there is a physical connection problem with a cable or switch/hub.

    The incorrect range was 169.etc.

    Everything seems to be working again now.  It looks as though ICS needed to be disabled and then setup again in order for everything to work.  Very strange.

    Thanks anyways. :)

    Re-enabling ICS probably restarted the DHCP service. Should it happen again just try opening the services management control panel on the ICS machine (enter  services.msc in the run box) and look for the DHCP server service, not DHCP client. Stop the service and re-start.

    Thanks for the update,
