Setting share files and printers seems to not be as easy as it was in XP and Vista. I tried all the forums so far and have not found the trick. With all options tried in Windows 7 as the forums state, one can not see the other non Windows 7 pc in a home that worked fine prior to Win7 with same hardware. Vista pc also can NOT open any files or share any printers as it did in past. PASS WORD PROTECT OFF OR ON fails to allow one to open WIN7 files. Can see Win7 pc from Vista and can see Win7 from xp pro public files only but shows in xp all other files that can be share but can not open any but those in public. Windows 7 share setup is too complicated and that is it(no files can be opened). Did not start Mcafee with msconfig and AVG on win7. Did not resolve short of uninstalling both which I do not see why. Windows 7 Pro Installed and other than share prob. all working fine. ALL PCs used WORKGROUP name. What is the hidden trick? FIREWALL OPTIONS IN WINDOWS 7 ? SUSPECT FIREWALL BUT NOT ABLE TO LOCATE where any are not checked for file sharing and printers within Win7. This definitely one area in Windows 7 that needs revamping for sharing to older systems.
