Request timed out in windows xp

That is the local loopback interface. If you are connecting computer-to-computer via crossover cable, the LAN is irrelevant. If you want to connect via LAN, put both in the same workgroup.

Best bet - Go to the Start menu, select Programs - Accessories - Communications and choose the appropriate networking wizard to guide you through the process. Choose New Connection Wizard, and you can select from a list.

Make sure that both computers have an Account on each System with the same Logon ID and password.
Connect each end of the cat5 crossover cable into the network cards of each computer.

Set both Systems with a common workgroup name of 15 characters or less. eg: workgroup

Press the Winkey + Pause/Break and select the Computer Name tab. Click the Change button. Change the Workgroup name and do the same on the second System.
Restart both Systems.

To get the Systems to communicate, the Ethernet adapters will need to be configured with a static IP address and a common Subnet mask. For example, assign one System an IP address of 192.168.1.1 and assign the second System an IP address of 192.168.1.2. Both machines should use the Subnet mask 255.255.255.0.

If your Main System is being allocated a DHCP address and is connected to the internet you will have to find out your IP address and set the second System up with a static IP address in that range.

Press the WinKey + r, type in cmd and press Enter.

Type ipconfig and press Enter.

eg:

C:\>ipconfig

Repeat the steps above for the second computer system.

Next, open a command prompt on one of the computers by pressing the WinKey + r, type in cmd and press Enter.

Type in ping 192.168.1.2 (if you are using the computer assigned with 192.168.1.1) press Enter.

eg:

C:\>ping 192.168.1.1

hi Howe
firstly i clear my position in more detail

First condition
i used single crossover cable for connecting both..

in which workgoup name is same, mannually i filled ip addresses which are different, No firewalls are on, i installed fresh XP too.

Secondly i used switch/hub
one cable to desktop and hub/switch
second cable to laptop and hub/switch rest all same...

thirdly i directly connect my laptop to router provided by ISP, using obtain an ip address option,

1) i also ping to 127.0.0.1 and got reply.

2) but if i ping to 192.168.1.1 (default gateway) then "request timed out"

3) no connectivity or limited connectivity i recieved

4) no ip address obtained

and if i use desktop with router then it is connected to internet and working fine...

hope you understand my position
