I am using Windows Vista Business 64 bit. My user account is the admin account on this machine, but I am logged in through my company's domain. Just wondering, is this setting unable to be turned off when connected to a domain? Otherwise, how do I get this option to show up so I can turn it off? I need to be able to access my shared folders from a printer which doesn't have login options so it needs to be unprotected. Thank you in advance for your help.
