How to share files and printers?

i have to computers:


Packard Bell (PB) - Xp, Ethernet port


Creative (c) - Xp, Ethernet port





PB receives the internet conection via a sagem 800 E2T ADSL USB modem. Then C receives the internet connection via the ethernet ports in both computers using an ethernet cross-over cable. Now, I've ';created a network'; (thats what both computers are telling me). I still can't share files or printers but it seems to be sharing the internet connection with no problems at all. can anyone help :SHow to share files and printers?
use the file and printing sharing wizard that's in network connection's option's. this will need to be done on both computer's.
