My small office recently bought two PCs and one laptop, all with Vista (Business edition). All the other machines here run Windows XP Pro. I was able to get the laptop to see all the networked computers -- Vista and XP --without too much trouble. Establishing a connection to a printer attached to an XP machine was a little tougher, but I managed to create a port for it and it's working just fine. The PCs, however, cannot find the XP ones no matter what I do. As far as I can tell the settings on the new PCs are identical to the laptop's (Private network, discovery on, etc.) and yet they still can't find the older machines. I've gone through a variety of sources, but no luck so far. Any suggestions? Thanks in advance, Cameron
