Part 1 How to Share Windows XP Operating System 1. Using Windows XP Shared Folders and Setting Permissions
This article describes how to share folders and files on a network using Windows XP. Mainly for the following aspects: 1, Microsoft network file and print sharing 2, Microsoft network file and print sharing components allow computers in the network to access resources on other computers through the Microsoft network. This component will be installed and enabled by default. The file and print sharing component is applied in units of connections via the TCP/IP protocol, and you must share local folders for the functions provided by the component. 3. The file and print sharing components of the Microsoft network have the same functionality as the server services in Windows NT 4.0. To share a folder with other users on the network, follow these steps: Open My Documents in Windows Explorer. Click Start, click All Programs, click Accessories, click Windows Explorer. Click the folder you want to share. Click Share this folder in the File and Folder Tasks bar. In the Properties dialog, check the Share this folder radio button (Figure 1) to share the folder with other users on the network. To modify the network share name of a folder, enter a new name for the folder in the Share Name text box. This action has no effect on the folder name on your local computer. Note: The sharing feature does not apply to Documents and Settings, Program Files, and Windows system folders. Also, you cannot share folders in other users' profiles. To set, view, modify, or delete file and folder permissions, follow these steps: Open Windows Explorer and locate the file or folder for which you want to set permissions. To open Windows Explorer, click Start, click All Programs, click Accessories, click Windows Explorer. Right-click on the file or folder you are targeting, select Properties from the shortcut menu that appears, and click the Security tab (Figure 2). To set permissions for groups or users that are not displayed in the Group or User Name list, click Add. Enter the group or user name for which you want to set permissions and click OK. As shown in Figure 2, to modify or delete permissions for an existing group or user, click the appropriate group or user name and do one of the following: To allow or deny a permission, in the Permissions list In , select the "Allow" or "Reject" checkbox. To remove a group or user from the Group or User Name list box, click Remove. Description
In Windows XP Professional, the Everyone group is not included in the anonymous login. You can only set file and folder permissions on a drive formatted with the NTFS file system. To modify a permission, you must be the owner of the file or folder or have administrative privileges granted by the file or folder owner. Groups or users who have Full Control permissions for a specific folder can arbitrarily delete files or subfolders from that folder, regardless of what permissions are protected by the corresponding file or folder. If the Permissions for a specific group or user check box is disabled, or if the Delete button is not available, it means that the permissions for the corresponding file or folder are inherited from the parent folder. By default, when a new group or user is added, the group or user will have Read & Execute, View Folder Content, and Read permissions. Second, the sharing between the same machine users
This sharing is designed for the situation of single-machine multi-user. If you only share a disk (optical drive) or folder between users of this machine, simply drag the drive letter or folder to "C:\\Documents and Settings\\All User\\Share Document" in Windows Explorer. . Windows XP really copies the contents of the disk or folder to the "shared document", so when there are too many shared files, it will take up a lot of local hard disk space. However, this also has its advantages, that is, even if the user destroys the files in the "shared document", it will not affect the source file, thereby improving the security of the data. I personally think that the practical significance of this sharing is not great, because the security of the Windows system is relatively poor, we can access each partition at will. Even if you don't share, as long as someone else can log into your computer, all the secrets are still visible. Third, the realization of LAN sharing
On other computers running Windows operating system in the LAN, you can remotely share files and disks through Network Neighborhood. Normally, as long as the computer is connected to the local area network and configured with the correct IP address information, Windows can find all the workgroups and computers on the network in just a few moments. For Windows Me, Windows 2000, and Windows XP, you can directly discover the folders available for sharing on the network and display them in the Network Neighborhood of Windows Explorer. What the user can do is just double click and open the folder of interest to you. Note: If you can't find a computer to share a resource in My Network Places, you can use the name of the computer to find the computer by looking up the computer. In addition, the IP addresses of the same network segment should be used between computers that implement sharing. Otherwise, they will not be found between each other. Fourth, how to remove the file sharing restrictions of Windows XP system
Have you encountered this situation: on the computer with Windows XP installed, even if the network connection and sharing settings are correct (such as the IP address belongs to the same subnet, enabled NetBiOS on TCP/IP, the firewall software does not prohibit ports such as 135, 137, 138, and 139 that are required for file sharing. Users who use other systems (including Windows 9X/Me/2000/XP, etc.) still cannot access the computer. How should we solve this problem? By default, the Windows XP local security settings require users to access the network in the guest mode. At the same time, the Guest user is prohibited from accessing the system through the network in the user rights assignment of the Windows XP security policy. These two conflicting security policies have caused other users on the network to access computers using Windows XP over the network. You can use the following methods to solve. Method 1: Unlock the Guest account Click “Start→Run”, enter “GPEDIT.MSC” in the “Run” dialog box, open the Group Policy Editor, and select “Computer Configuration→Windows Settings→Security Settings→Local Policies” → User Rights Assignment, double-click the "Deny access to this computer from the network" policy, delete the "GUEST" account inside. In this way, other users can use the Guest account to access the computer using Windows XP system through the network. Method 2: Change the network access mode Open the Group Policy Editor, select "Computer Configuration → Windows Settings → Security Settings → Local Policies → Security Options", double-click the "Network Access: Local Account Sharing and Security Mode" policy, the default settings will be "Guest only - local user since guest authentication", changed to "classic: local users authenticate with their own identity." Now, when other users access the computer using Windows XP over the network, they can log in with their own "identity" (provided that this account is already available in Windows XP and the password is correct). When the policy is changed, the way the files are shared is also changed. After the "Classic: Local users authenticate by themselves" mode is enabled, we can limit the number of users accessing shared files at the same time, and can set different for different users. Access rights. However, we may also encounter another problem, when the user's password is empty, the access will still be rejected. Originally, in the "Security Options", there is an "Account: Local account with blank password only allows console login" policy is enabled by default. According to the principle of rejecting priority in Windows XP security policy, users with empty passwords access through the network. Computers using Windows XP will be banned. We just need to disable this strategy to solve the problem. How to share access to encrypted files in Windows XP
This section describes how to share access to files stored using Windows XP Encrypting File System (EFS). Encryption is the process of converting data into a format that no one else can read. If the data is stored on your hard drive, you can use Windows XP's EFS to automatically encrypt the data. How to share access to encrypted files Note: Only members of the Administrators group or users who have encrypted the file can add users to the file. If you do not get the authorization to add a user to the encrypted file, you will receive the following error message: EFSADU Error in adding new user(s).Error code 5. You can preserve the security of file encryption while allowing specific users to access your Encrypt the file. To allow access to your encrypted files, do the following: Right-click the encrypted file and click Properties. Click the General tab (if it is not already selected), then click Advanced. Click Details and then click Add. Select the user you want to share access to the encrypted file with and click OK. Once you have added the user, click OK three times. The second part of Win 98 can not access Win XP solution in the LAN, you can often encounter a computer with Win 2000 opened a shared directory, and the computer with Win 98 can not access the Win2000 shared directory, the official in Microsoft The web page can find the answer, suggesting that you can open the GUEST user of Win2000. However, after Win XP came out, the same problem was faced. Some people found that this method was not working. Accessing XP's shared directory from My Network Places may not be allowed. What is the reason? This problem has also bothered me for a few days, but then I accidentally found the answer to the question, maybe this is a bug in Win XP. With System Guest user turned on, click Start -> Run and type gpedit.msc to bring up the Group Policy Editor in Local Computer Policy\\Computer Configuration\\Windows Settings\\Security Settings\\Local Policies \\User Rights Assignment\\Reject access to this computer from the network" You can see that there is a Guest user! If you delete the Guest user here, then other computers can view the shared directory of this computer from My Network Places. Note: Chinese Win XP uses the traditional login method and turns off "Use Simple File Sharing" in "Folder Options". The third part Win 2000 can not access Win XP reasons and solutions
