You may also find the following suggestions useful when troubleshooting ICs.
- If computers on the network are unable connect to Web sites via the shared Internet connection, check that you have the correct DNS server addresses.
- Type ipconfig at a command prompt to ensure that new IP settings have been applied correctly. You may need to reboot before all the settings become active.
- Check that the subnet mask is 255.255.255.0, otherwise or else the system that is trying to connect to the ICS computer will be unable to connect.
- Ensure that all the IP addresses assigned to other computers on the network are within the range 192.168.0.2 to 192.168.0.254, and that there are no duplicate addresses.
- If you have network devices that must have static IP addresses while using ICS, you will need to modify the Registry. The STOP value must be set to the maximum IP address within the 192.168.0.0/24 network that will be issued automatically to clients. Eg: if you set the STOP value to 192.168.0.200, the DHCP component of ICS will only issue IP addresses between 192.168.0.1 and 192.168.0.200. You could then allocate your network devices with static IP addresses greater than 192.168.0.200.
- If computers on the network can only connect to the Internet after you manually initiate the Internet connection from the ICS host computer, make sure that Establish A Dial-Up Connection Whenever A Computer On My Network Attempts To Access The Internet is checked on the Advanced tab of the Internet connection's Properties dialog box.
