Hi,this is my first post in this forum,so can somebody help if he knows how can I install windows XP on many computers at the same time on a network using one another.thanks for all caring.

What you are describing there is the principle behind the Remote Installation Service (RIS).

A client image is stored on a W2K or W2K3 server and the client machines boot using PXE (or from a CD) then have their installation files copied down across the network during install.

Couple of documents detailing the process:
