What network settings must be changed to make one computer exactly like another?

   I have two computers, a laptop and a dektop, both running XP Pro. The laptop is connected to a LAN. File sharing and internet work perfectly. The desktop can do neither. Both are plugged into the same hub. The desktop can view (sometimes) other computers on the network, but can not connect to them. [Computer is not accessible...network path was not found]. It used to be able to connect to the laptop, but this connection is also failing now. I have spent many hours troubleshooting this. What I'd like to attempt to do is make the network settings on the desktop match those on the laptop. Is this even a feasible idea? (The laptop is old and very slow). I have manually changed the MAC address in the BIOS, and the ipconfig printout is exactly the same. I have edited the route print, and they match exactly, except that the NIC on the desktop is marked 0x3.
This is the printout for the laptop:

What should I do??
Watch Question

what is connecting you to the internet?
cable modem?

- on your desktop under TCP/IP settings check box for obtaining IP automatically
- turn both computers off
- unplug the power to your modem
- wait about 1 min
- plug the power back into modem and startup only the desktop

if you now have internet then it is your modem, this is a common problem.
you need a DHCP router between your modem and hub.

why, some cable modem providers can update there firmware without you knowing.
and create conflicts, this will bypass your modem and you it only for the basics, the internet.

From your IP addresses, I hope this is your work network - those are public IP addresses and you should't use them if you're at home.

As Yohan said, you DON'T want the MAC and IP to be the same - this would be duplicate addresses and wouldn't work.

If you can ping one machine to the other, and vice versa, it's more likely a permissions issue in the OS despite what M$'s cryptic error message says.  Usually, for both machines being XP, if you have the SAME user account on both boxes and the SAME password, and they're in the SAME domain/workgroup then they should work for file sharing.



I am connected a T3 on my college's network. They require our MAC addresses in order to gain access. They supply an IP if detecting automatically doesn't work. My MAC and IP addresses are different. As a clarification, I no longer want to use the laptop at all, I just want Internet and file sharing (for the other 100  computers on the network) for the desktop. I can not ping between the two machines, but this is most likely because of an IP conflict. To be sure that I can access the network, I want to use the same IP on the desktop.
OK, so what exactly do you need help with?


I am trying to copy network settings, exactly, from the laptop to the desktop in order to get Internet and file sharing on the desktop. That's all.

If their network allows access via IP address, make sure you give them your MAC address and they can add it to their allowed list, rather than you changing to match their records.
