I find most don't complete the wizard or don't know about firewalls or that the printer driver may have to be installed before the share is connected to. Sometimes I have to install the printer per the maker's instructions and connect the USB port directly before I go across the network.

XP has added obstacles regarding accounts and more.

In this discussion http://forums.cnet.com/5208-6122_102-0.html?forumID=44&threadID=198031&messageID=2129068 we cover all this and more.

As this has almost every aspect covered I'll leave it to you to go over the networking, shares and firewalls we discussed before.
