Please. You should always share the exact information displayed for an error so those familiar with it may lend a hand.
1. The article [Q307874] explains that by default simplified sharing is enabled on a WinXP-based computer if the computer is not a member of a domain and allows simplified sharing of folders with everyone on a workgroup or network, and make folders in the user profile private. However, if simplified sharing is enabled, you cannot prevent specific users and groups from gaining access to your shared folders.
Note: Simplified Sharing cannot be disabled in Microsoft Windows XP Home Edition.
2. The Win XP Pro article [Q281249] explains that when a folder or hard drive is shared, if a user who does not have access to this share attempts to connect, the user is prompted for a user name and password. If the user connects successfully with the supplied credentials, and you then disconnect them from the share, the user can reconnect to the hard disk without typing in a user name or password. This behavior occurs because the Stored User Names and Passwords credentials are cached for the lifetime of the logon session.
Note: For information about using Shared Folders, click Help on the Action menu. Also in the Computer Management and Shared Folders consoles, the New File Share command is unavailable when right-clicking the Shares icon in the left-side pane and when right-clicking any listed share, the Properties command is missing when the Simple File Sharing user interface is enabled, [Q303248].
3. By default, the setting for shared folders through Explorer in WinXP Service Pack 1 is for everyone to have read-only access. This is also true for folders shared through the New File Share wizard and the Net.exe command. Before SP1, shared folders had default permissions that gave everyone full control, [Q328065].
4. Creating a CREATOR OWNER permission on the Effective Permission tab for a file or folder located in the main root folder of an NTFS file system drive, the security takes effect only in the root. The folder or file where originally assigning the permission does not show the CREATOR OWNER permission since permissions which appear in the main root folder apply to all of the root folders, [Q283391].
5. Folder permissions include Full Control, Modify, Read & Execute, List Folder Contents, and Read and Write, which consists of a logical group of special permissions. Simplified Sharing by default is enabled in WinXP connected to a domain, which means that the Security tab and advanced options for permissions are not available, [Q308419] and [Q308418]. If a system is not joined to a domain, to view the Security tab:
a. Click Start, Control Panel, Appearance and Themes, and then click Folder Options.
b. Click the View tab, and then click to clear the Use simple file sharing [Recommended] check box in the Advanced settings box.
Note: If only the permission Traverse Folder/Execute File is assigned to a program file, an Access denied error message may be received when the program is started which can occur should Windows require "Read permissions" to open it, [Q319777].
6. On WinXP-based computers that are configured as members of a workgroup in a peer-to-peer network environment, behavior such as the following may be experienced and may occur if both of the following conditions are true, [Q318030]:
a. NetBIOS over TCP/IP is not turned on (enabled) on one or more computers in the workgroup.
b. The Computer Browser service is not started or is turned off (disabled) on one or more computers in the workgroup.
? You cannot access shared folders or files.
? You cannot browse other computers in the workgroup.
? You receive the following error message when you double-click the workgroup in My Network Places:
Workgroup Name is not accessible. You may not have permission to use this network resource.
7. The article [Q304040] discusses the enabled new user interface (UI) that is known as Simple File Sharing that includes a new Shared Documents feature and how to enable, disable, configure, and troubleshoot file sharing. Windows XP allows for five different levels of permissions. Level 1 is the most private and secure setting and Level 5 is the most public and changeable (non-secure) setting. Levels 1, 2, 4, and 5 can be configured by using the Simple File Sharing UI by right-click the folder, and then click Sharing and Security.
Note: This article is quite lengthy, a video is provided, and may require a lot of study to fully understand.
