Firstly you need a network crossover cable. Available from most computer stores. This is a special type of cable (not a standard LAN cable)
Secondly Make sure both computers are on the same workgroup. TO do this Right click on My computer, Properties, go to the Computer Name Tab, See what is written in Workgroup. Change one computer by clicking on change and then type in the name of the other computer in the workgroup space down the bottom. Do not make the computer part of a domain. You want Workgroup.
This name change will require a computer reboot.
When both computers are on the same workgroup, we need to set IP Addresses.
In Control Panel, Open Network Settings.
Right click on Local Area Connections and select properties.
Under the heading "This connection uses the following items, Find Internet Protocol (TCP/IP)
Highlight it, Make sure you don't untick the box, and click on properties
Under the heading Use the following IP Address ENter in the Following on ONE Computer.
IP Address 192.168.0.10
Subnet Mask 255.255.255.0
Default Gateway LEave Blank
Under the Heading Obtain DNS Serveraddress automatically
Set this to Automatic. Don't enter anything in.
On the second computer Make the IP Address 192.168.0.20
Measure the distance between the two computers and write down the length. Purchase an Ethernet crossover cable that is slightly longer than the measured length (see Resources below).
Power off both computers completely. Connect one end of the crossover cable to the Ethernet network port on the back of one of the computers. Run the cable across to the other computer, and connect the other end into the computer's Ethernet port.
Turn both of the computers back on, and wait for their operating systems to finish loading. Click on the "Start" button on either of the computers and then choose the "Control Panel" option. Scroll down through the list of options, and click on the icon labeled as "System."
Wait for a new window to pop up asking if you want to proceed, and click on the "Continue" button. Scroll down to the "Computer Name" heading, and write down the entry listed under "Workgroup."
Go to the second computer, and access the System menu in the Control Panel. Scroll down to the Computer Name heading, and click on the "Change" button. Type in the work group name you wrote down earlier in the "Workgroup" text box. Click on the "Apply" button.
Restart the computer to save the workgroup change. Navigate back to the Control Panel, and click on the "Network and Sharing Center" icon. Choose the "View Computers and Devices" option to gain access to the other computer's files and folders.
first cross cable crimping, after two laptops connectivity the LAN ports. your first checking the lan drivers install or not install. lan drivers install after I.P.Address in LAN.
For Example: I.P. address : 192.168.100.2
Subnet Mask : 255.255.255.0
Another laptop I.P.Address : 192.168.100.3
Subnet Mask : 255.255.255.0
now ok. run your laptop checking for ur files sharing and enjoy the work.
Crossover cable's are different than normal Lan cables. You can purchase the crossover cables from any computer shop. They cost around $5. If you want to be more technical about crossover cables, just google it. You can also buy a crossover adapter if you don't want to buy a crossover cable. But yeah, you need a crossover cable to connect 2 PC's to each other.
