OK, so all your PC's are able to get onto the Internet via MASTER?
That means they've all got TCP/IP up and running by the looks of things.
What are you trying to "see" on the other PCs? If it's shares, you need to share the drives and you will need NetBEUI installed.
Have a peek in My Network Places first, and see if any of the machines can see any of the other machines, then also check out Control Panel -> Network -> and see what protocols apart from TCP/IP you have installed.
I posted on this a while ago, NetBEUI is the necessary protocol on a small LAN without any WINS server and other kit..... your mileage may vary without it! You should have TCP/IP AND NetBEUI.
Also remember that in order to see other computers you may well need to share something on them (like the C or D drive) in order to make them "visible".
Also, have you got any firewalling software installed? If not, you should have, if you have then well done.... but make sure it isn't blocking requests for the LAN on any of the machines.
Hope this helps
