Did you allow such traffic on your firewall?
I have two Dell computers, one running Windows XP Home and the other running XP Pro. They are both connected to a Linksys Cable/DSL Router to share the DSL connection, which is working fine.
I am trying to set up file and printer sharing. I have placed both computers in the same workgroup, but neither one is detecting the other simply through the router. Do I need to purchase a hub or a switch to connect the two PCs, and then connect the hub/switch to the router? Or can I simply reconfigure the router?
