Monitoring over lan

[debaisaindian]

I have a small network of about 8 computers.They computers are connected to the switch.All the computers are running over Windows XP pro.There is no server configured.Is there any software that can visually monitor the other computers in the network without instlling a client software in the remote machine.
Thanks in advance.
