Windows XP Pro SP3sec.pol.msc --> Security Settings--> Local Policies --> Security Options --> "Network Access: Sharing and Security model for local Accounts" double-clicking --> "Explain this settings" tab tells:"There are two models available:Classic: Local users authenticate as themselves.Guest only: Local users authenticate as Guest.Default:Guest only on Windows XP Professional.Classic on the Windows Server 2003 family and Windows XP Professional computers joined to a domain.Important:With the Guest only model, any user who can access your computer over the network (including anonymous Internet users) can access your shared resources. You must use the Internet Connection Firewall (ICF) or other similar device to protect your computer from unauthorized access. Similarly, with the Classic model, local accounts must be password protected; otherwise, those user accounts can be used by anyone to access shared system resources.This setting only affects computers running Windows XP Professional which are not joined to a domain."What does the last phrase mean?And how one can interpret this setting on Windows XP Pro with (Windows Explorer --> menu Tools --> Properties --> View --> ) "Use simple files sharing (Recommended)" checkbox marked?1 person needs an answerI do too

An XP Professional computer that's joined to a domain always uses the "Classic" security model for local accounts. Changing the setting that you found has no effect.A Windows XP computer that isn't joined to a domain is automatically a member of a workgroup. In a workgroup, XP Professional uses the "Guest only" security model by default. You can change it to "Classic" in Security Options.Putting a check mark in the Use simple file sharing (Recommended) box selects the "Guest only" security model. Un-checking that box selects the "Classic" security model.Boulder Computer Maven Microsoft Most Valuable Professional

HiYou can also configure the access to guests and others by using the permissions.http://www.microsoft.com/windowsxp/using/security/learnmore/accesscontrol.mspx#securityTab Jack-MVP Windows Networking. WWW.EZLAN.NET

What to do when simple file sharing is turned off, security options are set to "classic" and upon reboot, the setting changes back to "guest only"?I have two computers that need a specific user (with administrative rights) to gain access. But the "Network Access: Sharing and Security model for local Accounts" settings will not stick!
