At both my Vista laptop and my Win XP computer, I can access files on my Win 7 computer. From the XP computer, I can print to a printer that is hard-cabled to my Win 7 computer. I have not yet figured out how to print from the Vista laptop to the Win 7 printer, nor from the Win 7 computer to the printer tht is hard-cabled to the Win XP computer, but it is not crucial, yet. Accessing files and printer on the other two computers from the Win 7 computer has not been setup properly. On the Win XP computer, I go to Control panel/Network setup wizard/. . . /"name your network". There is a blank field for "workgroup name" and an instruction that the same name must be used for all computers on the network. I partly set up the network about 8 months ago, and cannot remember the workgroup name. How do I recover that name? Just to be able to use the network to the extent that I already do, I obviously did partly setup the network. BTW, PC World had an article several months ago on how to network Win 7, XP, and Vista. I followed every step possible, but the instructions must be imperfect. Canon also has a document allegedly telling how to network printers, and I can print on the Win 7's printer from my Win XP computer, but not the other way around. The Canon document is also imperfect. There may be several more stumbles in my path forward, but before I can go any further, I must know what "workgroup name" to put into the appropriate field on my Win XP control panel wizard. Please tell me how to navigate to the specific answer.
