The second check box is for shared files and folders. You will
need this if you want to see another PC directory or share
folders/files with other PCs. If it is not listed, click on install,
then select services. Click on OK, select files and printer
sharing and finally click on OK.
The third check box is the protocol supported by your network.
The TCP/IP protocol is a must for most network applications. If
you do not have it, click on install and select protocol. Click
on OK, select TCP/IP and finally click on OK.
If you have performed any of the functions above, you will
need to restart your computer. Do this before proceeding.
4 Select TCP/IP Properties and click on Properties. A window
like the one below should be displayed.
If the option to "obtain an IP address automatically" is
available, you should also have the "Obtain a DNS server
address automatically" option. To obtain an IP address
automatically relies on a DHCP server.
If you have a network that has a DHCP server, it is highly
recommended that you leave the settings unchanged.
Once your network adapters have been configured on both
PCs, you can check if they are able to talk to each other.
Below, you can find out how to check the configuration settings
of your network (DHCP, IP, DNS, gateway...)
