Lan sharing permission settings: xp has no permission to access win7 share, and win7 has no permission to access xp

Lan sharing permission settings: xp has no permission to access win7 share, and win7 has no permission to access xp
Lan sharing permission settings have always been one of the network skills that administrators must master. However, because the access permission settings for windows shared files are complex, it is difficult for network administrators to fully master how to set the LAN shared permissions. Therefore, this article summarizes two methods for setting LAN shared file access for the majority of network administrators:
Method 1: Use a dedicated shared file access permission setting software to control access to shared files on the LAN.
At present, there are a lot of dedicated shared file access permission settings software in China, for example, there is a "share to shared folder permission settings software" (: http://www.grabsun.com/gxwjjm.html ), after the shared file is installed on a computer, you can set the shared file access permission to prohibit the copying of shared files only by reading shared files, you can only modify shared files to prevent the deletion of shared files. You can only view shared files and save the shared files as local files. In addition, you can also prevent the sharing files from being dragged to the visitor's local computer, this prevents shared files from being sent by means of USB flash drives, network disks, mobile hard disks, FTP file uploads, QQ File Sending, and email attachments, so as to fully protect the security of shared files, prevent leakage through various channels. In addition, the shared folder management software can record the visitor's IP address, MAC address, host name, and other information in detail, records various access operations (such as opening, copying, modifying, deleting, cutting, renaming, and printing) on shared files in detail, so that network administrators can audit shared file access logs in real time, better management of shared file access. As shown in:

Method 2: Use the user and folder access permissions of the operating system.
Lan and WIN7 Operating Systems with more than two computers
STEP/Method
1. Right-click desktop network-properties-change advanced sharing settings (Note: view the current network, such as the home network and public network !) "I am a public network"

 
2. select public network-select Startup network discovery-startup file and printer sharing-enable sharing so that users who can access the network can read and write files in the public folder (optional) ---- Disable password protection sharing (Note: other options are available by default !)
3 save!

 
4. Right-click the folder to be shared (such as DY) and choose Properties.

 
5 Share ---- Select Share (S)... --- the pop-up dialog box --- add "Guest" (Note: Selecting "Guest" is to reduce permissions so that all users can access it easily !) --- Sharing

 
6. Select advanced sharing... ---- share this file ---- OK!

 
7. other users can access your shared files by running --- \ IP (shortcut: WIN + R) \ IP!

 
8. Shared successfully!
Establish a local network based on infrastructure
When building a home network, the latest Win 7 system is much simpler and more convenient, thanks to the system's "network discovery" function. In addition, compared with the XP system, the Windows 7 system can also choose different environments, such as the home network, work network, and public network, with higher security. In addition, from an application perspective, in addition to traditional file sharing, Win 7 allows media file sharing in the form of a playlist.
Step 1. Uniform Working Group Name
To establish a LAN smoothly, all computers in the LAN must have the same working group and different computer names. In Windows 7, the procedure is simple. Right-click "computer" and choose "properties" from the shortcut menu ", in the displayed window, modify the name of the Worker Unit and computer where the computer is located under "computer name, domain, and workgroup Settings.
Step 2. Set the home network
Set the home network in Win 7 and open "network and sharing center" in the control panel ", click "select family group and sharing options> change advanced sharing Settings" to set the LAN environments "home and work" and "public. Expand the "home or work" network. The following table lists the required items.

 
Next, click "view active connections" in "network and sharing center" to select different network locations on the next page.
Master Dong suggested: In Win 7, you can select three modes: "Home Network", "Work Network", and "public network. However, the settings here are only "home and work" and "public. Originally, it has unified the "home network" and "Work Network. However, if you select "Home Network", you need to set the password. Therefore, to facilitate shared access, we recommend that you select "Work Network" or as appropriate.
You can use the network installation wizard to complete the home network settings in XP. Double-click "Network neighbors" on the desktop, and select "Set Home or small office network" from the pop-up window to start the network installation wizard, and then follow the prompts in the Wizard to perform the operation.
Enable Guest account to achieve mutual access between XP and Win 7
To allow smooth interaction between XP and Win 7, open the Guest account. In XP, select "management tools> Computer Management" in the control panel, and then select "local users and groups> Users" in the pop-up window ". Next, double-click "Guest" on the right. In the displayed dialog box, clear the check box for "Account Disabled, then confirm that the "Password Never Expires" option has been selected (the setting method in Win 7 is similar ).
Master Dong's prompt: Make sure that the password never expires. If you access the shared folder again in the future, you do not need to change the password, which is more convenient. Of course, you can set it according to the actual situation. In addition, the exchange and sharing of XP and Win 7 (such as printer sharing) may cause many strange problems. We will not list them here. The solution is not only to enable the Guest account and ensure that the two computers are in the same working group, but also to make basic sharing settings, please set up the firewall for XP and Windows 7 in detail, it can be solved in general.
 
File sharing and integration of multiple file resources
After creating a LAN, you can create different folders to share file resources between different computers. When Windows 7 is installed, the system automatically creates a user named "public" for us and creates a folder named "public" on the hard disk. In the previous settings, we have selected to allow public folder sharing, so other computers in the LAN can access this folder. For normal file sharing, you only need to copy the files to be shared to the "public" folder. For more flexible applications, you need to set them manually.

Note: The Windows 7 environment is described as an example below. The settings in the XP system can be performed as a reference.
Step 1. Basic sharing settings
We will Share the Share folder under the root directory of the E drive of a computer. Right-click the Share folder under the root directory of the E drive and select "Properties> Share ". In the displayed dialog box, click share. In the displayed dialog box, select "Everyone" as the username, and click "add" to display it in the following list box. Next, set the permission for it under "permission level", for example, "read/write" or "read" (1 ).
Master Dong prompts: To cancel sharing, you can use the same method. In "Properties> sharing> advanced sharing", clear the "share this folder" check box.

 
 
Step 2. assign different Permissions
Basic sharing settings may not meet the needs of more users. How can I set different sharing permissions for different users? Next we will illustrate how to share a folder named "project pictures" with different names ("project picture DX" and "project picture ZD: if the account you log on to is DX, you have read and write permissions. If the account you log on to is ZD, you only have read permission.
First, right-click "computer" on the desktop and select "manage". In the displayed Management window, expand "local users and groups → users" on the left ", click "Operation> new user", enter "DX" after "User Name", and set the password. Then, deselect the "user must change password upon next login" check box and select "Password Never Expires ". Click "CREATE" to generate a "standard user" level system account. Similarly, create a similar system account named "ZD.
Then, you can set permissions for the two accounts. In the "share" option of the folder, select "Advanced share> share this folder" and enter a name (such as "project picture DX") under "Share Name "), click "permission> Add> advanced> Search now", find the created account "DX", and click it to add it. Finally, select "Full Control" under "allow", as shown in figure 2. In addition, you can also see a user named Everyone and have full control permissions. Please delete it ). After the configuration is complete, you will have read and write permissions when logging on to the folder with the DX account and accessing the folder. Similarly, if you set the ZD user permission to "read", you will only have the read permission when logging on to the folder with The ZD account.

 
Next, you need to assign user permissions. Choose Start> Control Panel> Administrative Tools> Local Security Policy. In the displayed dialog box, click Security Settings> Local Policies> user rights assignment on the left ", find "Access this computer from network" on the right and double-click. Then, click "add user and group" to add DX and ZD. Then, expand "Security Settings> Local Policies> Security Options" and find "Network Access: sharing and security mode of the Local Account" on the right ", double-click and select "classic-Local User Authentication ". Now, all sharing settings are complete.
Media sharing family entertainment Security sharing
Similar to common file sharing, media files can also be shared. However, in Win 7, there is also a safer form of media sharing-sharing media files in the form of playlists. In this way, the visiting computer does not access the media file itself, so you do not have to worry about the destruction or malicious copying of the file. At the same time, the shared content can be controlled by classification, it is ideal for family users.
Step 1. Media sharing settings
Double-click "network" on the desktop, click "network and sharing center" in the window that opens, and click "select family group and sharing option> change advanced sharing Settings" in turn ", expand "Family and Work", find the "media stream" under it, and click. Select "all networks" after "display device location", and then click "all allow ".
After the preceding settings are complete, go to the "media stream options" window under "network and sharing center" and you will be able to see the name of the added computer, click the "Custom" link after the computer in the network (3 ). The content displayed in the pop-up dialog box does not limit media sharing. Next we will begin to modify it.
First, deselect the "use default settings" check box and select "only", and then select the level.
Master Dong prompted: to ensure that no classified media files are under control, please deselect the "include unclassified Files" check box.

 
Step 2. shared media playback
After the settings are complete, when other computers run Windows Media Player, you can view the playback list of the local machine in the left-side pane, you can also find the computer icon that shares media files under "Other media libraries" to find the shared playlist of the computer and play the shared media files (4 ).

 
Master Dong prompted: In the XP system, media playback lists cannot be shared. This function is only available for media sharing access between Windows 7 systems.
Tips for setting up LAN sharing for security
As we all know, lan sharing has become the main way to spread viruses while facilitating our daily use. Therefore, when configuring LAN sharing, you must set detailed access permissions. Only by ensuring the security of sharing can you make better use of the convenience of LAN sharing. In addition, the LAN Interconnection Between XP and Win 7 is not as troublesome as you think. As long as you follow the methods described in this article to prepare for the basic work, the smooth exchange between XP and Win 7 can be achieved. The media sharing feature provided by Win 7 brings more practical options and convenience for our entertainment.

In short, to achieve smooth access to shared files on the LAN, on the one hand, you must be familiar with the functions related to setting the shared file access permissions in the Windows operating system, on the other hand, you can also use dedicated LAN shared file management software and LAN shared file access control software to truly achieve LAN shared file access permission management.
