Troubleshooting file sharing in Windows XP
Expected upgrade behavior
A Windows 2000 Professional-based or a Windows NT 4.0-based computer that is joined to a domain or a workgroup that is upgraded to Windows XP Professional maintains its domain or workgroup membership respectively and has the classic file sharing and security UI turned on. NTFS and share permissions are not changed with the upgrade.
By default, if you upgrade a computer that is running Microsoft Windows 98, Windows 98 Second Edition, or Windows Millennium Edition that has "per share" sharing permissions to Windows XP, Simple File Sharing is always turned on. Shares that have passwords assigned to them are removed, and shares that have blank passwords remain shared after the upgrade.
If you upgrade a computer that is running Windows 98, Windows 98 Second Edition, or Windows Millennium Edition to Windows XP Professional and that computer is logged on to a domain, if that computer has share level access turned on and joins the domain while the Setup program is running, the computer starts with Simple File Sharing turned off.

By default, a Windows 98, Windows 98 Second Edition, or Windows Millennium Edition-based computer that is upgraded to Windows XP Home has Simple File Sharing turned on.
Known issues
For remote users to access files from the network (Levels 4 and 5), the Internet Connection Firewall (ICF) must be disabled on the network interface that the remote users connect through.

When Simple File Sharing is turned on, remote administration and remote registry editing does not work as expected from a remote computer, and connections to administrative shares (such as C$) do not work because all remote users authenticate as Guest. Guest accounts do not have administrative rights. When Simple File Sharing is turned on, if you configure specific user ACEs, remote users are not affected when Simple File Sharing is turned on because all remote users authenticate as Guest when Simple File Sharing is turned on.
Remote users may receive an "Access Denied" message on a share that they had connected to successfully before. This behavior occurs after the hard disk is converted to NTFS. This behavior occurs on Windows XP-based computers that have Simple File Sharing turned on that were upgraded from Windows 98, Windows 98 Second Edition, or Windows Millennium Edition. This behavior occurs because the default permissions of a hard disk that is converted to NTFS do not contain the Everyone group. The Everyone group is required for remote users who are using the Guest account to access the files To reset the permissions, unshare and reshare the affected folders.

Behavior that is affected when Simple File Sharing is turned on
• The Simple File Sharing UI in the properties of a folder configures both share and file permissions.
• Remote users always authenticate as the Guest account.

• Windows Explorer does not retain permissions on files that are moved in the same NTFS drive. The permissions are always inherited from the parent folder.
• On Windows XP Professional-based computers that have Simple File Sharing turned on and Windows XP Home Edition-based computers, the Shared Folders (Fsmgmt.msc) and Computer Management (Compmgmt.msc) tools reflect a simpler sharing and security UI.
• In the Computer Management and Shared Folders consoles, the New File Share command is unavailable when you right-click the Shares icon. Also, if you right-click any listed share, the Properties and Stop Share commands are unavailable.
Behavior that is not caused by turning on Simple File Sharing
• In Windows XP Home Edition, the Computer Management snap-in does not display the Local Users and Groups node. The Local Users and Groups snap-in cannot be added to a custom snap-in. This behavior is a limitation of Windows XP Home Edition. It is not caused by Simple File Sharing.
• If you turn off the Guest account in the User Accounts Control Panel tool, only the guest's ability to log on locally is affected. The account is not disabled.
• Remote users cannot authenticate by using an account that has a blank password. This authentication is configured separately.
• Windows XP Home Edition cannot join a domain. It can only be configured as a member of a workgroup.
