hi, on my network i have 3 desktops, one of which runs vista, and 2 laptops. besides the one that runs vista all of them run windows xp. they all can connect to my network and access the internet, but none of them can "view workgroup computers" or ping any other computer on the network. i've been trying to share a printer between all of them but simply cannot figure out how to do it. any help would be appreciated. thanks in advance!
