tnn said : IP Configuration: Now that you have PCs hooked into a network all that is left is to configure the machines to interoperate. If you have a network device that has a DHCP server built-in then all we have to do is map the network drives in Part 3. If you are not using DHCP then you have to configure the NICs manually. There are several private network ranges; one of the main IP range is 192.168.0.0 with subnet mask of 255,255,255,0 which allows 243 IP addresses. PC1 IP configuration is as follows: IP 192.168.0.100, subnet mask 255,255,255,0. PC2 IP configuration is as follows: IP 192.168.0.101, subnet mask 255,255,255,0. Once all NICs have been configured then you should go to Part 3 (Mapping Network Drives).
