I have 2 PCs on my home network. When they were both Vist all was well. Then I "upgraded" one of the 2 to Windows 7 (it was a free upgrade with the new Dell PC). Now everything works pretty well, I THINK, but the Win 7 Dell does not recognize, or can't find, the Vista PC or network, and consequently can't use the Printer connected to the network. Am I stuck, or is there an answer to my delima?ThanksLeo
