I've got a Vista Business x32 box and a Windows 7 Home Premium x64 box on my local Workgroup. Each box sees the other box on the network. Vista can access all the Win 7 shares. Windows 7 cannot access Vista.
On each box, network discovery is turned on, as is file/printer sharing. I have passwords turned off. I have rebooted both boxes after making changes. When I try to access Vista in Windows 7, I get a user/password query nonetheless, and I am denied access because of incorrect user or password.
The account name and password on each box is the same, and they are very simple, with no practical chance for input error. The workgroup is via router. Windows 7 is wireless, Vista in over ethernet.
One other thing puzzles me. When Windows 7 first accessed Vista, I saw the entire Vista User folder structure wide open. I can't imagine how it was deemed sharable. I went into Vista, and though Sharing wasn't enabled on the Properties sheet, when I clicked Advanced it was. I unshared there, and the problem was solved. But why were these folders accessible in the first place, and why didn't their shared status show on the Properties sheet without delving deeper?
