Let me explain what I have!

I have an XP PC (can't remember off hand the exact version, will add when I can go back to other side of house and check it). This machine is hardwired to a Westell Router the ISP gave us. Connected to this PC is a printer that I have shared. I have 2 Vista laptops, a Windows 7 laptop and another XP laptop (media center edition) that are connected to the router via wifi. I have another printer connected to the XP media laptop that is shared and I can print to it from the 4 laptops.

Neither of the windows vista laptops, w7 laptop nor media center laptop can connect to the xp PC. I've tried pinging IP or pc name but neither gets a reply. They are all connected to the same workgroup, have run the sharing wizard on the xp machines but now I am stumped!

In order to install the shared printer on the vista machine I had to install the printer as a local printer but then select another port and type in \\computername\printershare to install it. Any other way just wouldn't work. I was able to print to this shared printer on this pc in the past but then jobs started getting stuck in the queue. We just got a new color laser jet this week so had to try it again!

I am hoping someone can help me resolve this once and for all!
