Can any guide me to find, TCP/IP setting in my Windows XP computer?
You can do this setting in Window XP.
I will provide you with its complete detail. Please follow these pictures. To setup TCP/IP connection on an XP computer, open the Network Connections folder, right click the "LAN Connection", and select Properties.
Click the "Internet Protocol (TCP/IP)"
Make sure that ONLY the "Internet Protocol (TCP/IP)" is checked. DO NOT check any other network type unless you are sure what you are doing. Please note that enabling "File and printer sharing for Microsoft Networks" is extremely dangerous. If you have to enable this feature, to make disks/printers on your PC to be available to other computers (like others at home or at your office) you should also install a firewall program to limit access to your PC. We recommend ZoneAlarm which is a free utility for non-profit use.
Click the "Properties" button.
Click the "Use the following IP address" option and fill in the form.
with the parameters provided to you, during Loj-Net registration. All the IP numbers shown in the following screenshot are examples. You should fill-in the IP addresses that start with "139.179....".
Fill in the IP Addresses, for the Primary and Secondary DNS Servers too.
Click OK to finish TCP/IP Settings.
