New to Vista - currently have Vista Home Premium on new HP machine - Other machines on the network are running XP Pro. The Vista machine can access other PC's drives, but the XP machines have trouble accessing the C drive, and printing via printer attached to the Vista machine. The XP machines can access a folder added to the desktop, the public folder, and a file I created sitting in folder C:\Temp.\n\nI have "Network discovery", "File Sharing", Public Folder Sharing", and "Printer sharing" set. I have "Password protected sharing" off\n\nWhen I set up the C drive for sharing, I see reference that the drive is being shared, but never had option to change the sharing permissions - e.g, dialog - "Choose people to share with". The "Share" button on sharing tab is not available.\n\nAny ideas on why the printer and teh C drive is not accessible?
