This is the description of my experience. May be I did wrong, I did unnecessarily a lot. But I did it. I should thank my friend Zubair for his help. You can follow this.
Say two computer named A and B. Both are running windows XP sp2.
A
————–
– has two NICs say named NIC_A1 and NIC_A2.
– NIC_A1 is used to connect to the broadband internet.
– NIC_A2 will be used to share this internet to computer B.
– Internet provider gave the following settings to the NIC_A1
ip: 10.–.–.– [not written for safety]
subnetmask: 255.0.0.0
defaultgateway: 10.–.–.– [not written for safety]
preferred dns : 202.–.–.– [not written for safety]
Internet provider also took the mac address of NIC_A1 for their identification
B
—————
-has a NIC say named NIC_B1. This will be used to build the local LAN between computer A and B.
The procedure:
————————————-
1) First confirm that local LAN is okay.
1.1) Configuring NIC_A2
1.1.1) Right click on NIC_A2.
1.1.2) Go to Properties.
1.1.3) Deselect all but the last
1.1.4) Select Internet Protocol (TCP/IP). Go to properties and set the following things
ip: 192.168.0.1
subnetmask: 255.0.0.0
1.1.5) Turn off firewall.
1.2) Configuring NIC_B1
1.2.1) Do the same as above.
1.2.2) but the configuration will be like the following
ip: 192. 168. 0. 13
subnetmask: 255. 0.0.0
defaultgateway: 192.168.0.1
preferreddns: 192.168.0.1
1.3) check local Lan is okay
1.3.1) ping each other.
2) Sharing internet from A
2.1) right click on NIC_A1 and go to properties
2.2) Go to advanced
2.3) Select network setup wizard link from below.
2.4) follow the links until you reached a window with 3 radio buttons option where you are asked to select one of the 3 options. Select the first one i.e. your computer is directly connected to the internet.
2.5) do the next works until you are asked to make a network setup disk.
2.6) enter your pendrive into the computer. and do create a disk into the pendrive.
2.7) then take the pendrive into another computer B. Run the script.
2.8 ) In this case you need not to build any disk at the last step. Select the last option.
2.9) restart computer B
3) Check whether connection is okay.
3.1) ping from both computer.
i.e. ping from B to the 192.168.0.1
ping from A to the 192.168.0.13
3.2) ping from B to the default gateway address of NIC_A1
ping from B to the predefined dns of NIC_A1
