I have almost successfully set up my home network. I have a desktop running
XP Home and a laptop running Vista Home Premium. I have a printer connected
to the desktop that I would like to wirelessly access from the laptop. The
computers are both in the same work group, both computers have the Windows
Firewall configured to share files and printers, I have a Vista compatible
driver for the printer installed on the laptop, and all the other settings
seem to be correct. When I try to add the printer to the laptop, it is found
to exist on the network, but I get an error message indicating that access is
denied when I try to connect to it.

What am I missing?
