Several ways to improve the shared transmission speed in the LAN

Since the "shadow" of the client system such as Windows Vista, Windows Server 2008, after the frequent occurrence in the local area network, the shared resources under the corresponding system environment have also been new through the network. The idea. This is not the case, the following summary of the operation details can help us to share connections efficiently!

1, enable offline settings, optimize shared connection performance

Windows Vista or later system new The offline setting function has been added, and the function is used skillfully, so that the computer system can automatically cache the shared resources that we frequently access to the local hard disk. When the network connection fails to work normally in the future, we can quickly Access to content in the target shared resource; it is clear that cleverly enabling the offline setup feature can greatly optimize shared connection performance. Here are the specific steps to enable offline settings and optimize shared connection performance:

First, click Start /Programs /Accessories //in the desktop of the computer system where the target shared resource is located. Windows Explorer command, in the pop-up System Explorer window, find the folder where the target shared resource is located, right-click the shared folder, and click the "Properties" command from the pop-up shortcut menu to open The attribute setting window of the target shared folder;

Secondly, click the "Share" tab in the setting window, and click the "Advanced Sharing" button in the corresponding tab setting page that pops up to open the advanced sharing of the target folder. Dialog box, select the "Share this folder" option in the dialog box, and click the "Cache" button to open the cache settings dialog box;

Then check the "Users from the settings dialog box" If all files and programs opened by the share are automatically available offline, the option is selected, if it is found that the option has not been selected, We should re-select it in time, and remember to select the "Performed performance optimization" option, and finally click the "OK" button to save the above settings, so that we will access the target shared resources again through the network in the future. The shared connection performance is not affected by the state of the network connection and is always stable.

2, cleverly set the protocol to ensure the stability of the shared connection

In the LAN working environment, some special computer systems may be configured with several IP addresses at the same time, try to do in such a computer system When sharing access connections, we sometimes encounter a very strange shared connection failure, that is, each time the computer system is restarted, the same shared resource connection is sometimes normal and sometimes not normal, but if the IP address of the computer system is only set For one time, the target shared resource connection can always be stable. What is the reason? How can we solve this strange shared connection failure?

This failure phenomenon is mostly caused by improper setting of the shared access protocol of the target computer system. We know that the Windows system needs to use the SMB network protocol when making shared access connections. The network protocol currently supports both Direct hosting and NetBios Over TCP/IP working modes, and the SMB network protocol will be randomly used each time the system is booted. In the working mode, when the NetBios Over TCP/IP working mode is selected, the local computer automatically uses the first IP address of the local network card for the shared access connection. If the first IP address is exactly the same as the computer system where the target shared resource is located, When you are on the same working network segment, then sharing the access connection is naturally not normal. Obviously, in order to ensure that the shared connection is always stable, we can follow the setting below to let the computer system always use the Direct hosting working mode for access. After all, this mode does not use the first IP address for shared access connection. Use all IP addresses in turn for shared access until you reach the target shared resource:

First open the Start menu in the local Windows system desktop, click on the "Settings" /"Network Connection" command Go to the network connection list window of the local system, right-click the local connection icon connected to the target shared resource, and then click the “Properties” option in the pop-up context menu to open the property setting dialog box corresponding to the local connection; Br>

Next, click the “Internet Protocol (TCP/IP)” option in the “General” tab settings page of the settings dialog box, and click the “Properties” button. A TCP will automatically appear on the system screen. /IP protocol settings dialog box, click the "Advanced" button, pop up the advanced TCP /IP protocol settings dialog;

Then click the "WINS" tab in the settings dialog box to open the WINS tab settings page. On the "NetBIOS Settings" tab of the page, select the "Disable NetBIOS over TCP/IP" item and click "OK". The button saves the above settings, so that when the local Windows system makes a shared access connection in the future, the SMB network protocol can always work in the Direct hosting mode, and the shared access connection will always be stable.

3, turn off remote differential, improve shared connection speed

When trying to access shared resources on the LAN in Windows Vista or Windows Server 2008 system, we often feel that the shared connection speed is obviously not as high. So fast, is this the Windows Vista or Windows Server 2008 system that limits the speed of shared connections? The answer is no. The main reason for the slow connection speed is the new remote differential compression function corresponding to the computer system. This function automatically compares the similarities and differences between local and remote resources when sharing connections, and shares the shares to be transmitted. The content is compressed, and obviously these links slow down the shared connection speed. In order to improve the shared connection speed, we can turn off the remote differential compression function in Windows Vista or Windows Server 2008 system as follows:

First open the "Start" menu in the local computer system desktop, and then click on it. Select the "Settings", "Control Panel" command, in the pop-up system control panel window, click the "Programs", "Programs and Features" option, in the program and function list window that appears, click left The "Turn Windows feature on or off" option in the side task list area;

Secondly, find the "Remote Differential Compression" option from the list window, check the selected state of this option, by default Windows Vista or Windows Server The 2008 system will automatically select the “Remote Differential Compression” option. At this time, we should cancel the selected state of the option in time, and finally click the “OK” button to perform the parameter setting save operation, so that the remote differential compression function will not drag the shared connection. Speed ​​is up.

4, set the sharing mode, avoid sharing connection verification

We all know that each time you make a shared access connection, if the system automatically pops up the authentication dialog box on the screen, ask to enter the shared connection account With the password, then the sharing efficiency will not be very high. If the password is forgotten for a long time, then the user can only look at sharing resources. In fact, as long as we set the computer system group policy parameters of the shared resources, we can avoid the system to authenticate the shared connection, so that the sharing efficiency can be greatly improved, the following is the specific setup steps:

First, click the “Start”/“Run” command in the computer system where the shared resource is located, and execute the “gpedit.msc” command in the pop-up system running dialog box to open the group policy console window of the corresponding system. ;

Next, in the list on the left side of the console window, select the "Computer Configuration" branch node, and then expand "Windows Settings", "Security Settings", "Local Policies", "Security" from the bottom of the node. "Options", from the "Security Options", find the target group policy "Network Access: Local Account Sharing and Security Model";

Then double-click the option with the mouse to open the settings dialog box and select "Guest only - right The local user authenticates, its identity is the guest option, and then clicks the "OK" button, so that the shared connection operation After not need to authenticate a.

Of course, in the Windows Vista or Windows Server 2008 system environment, we also need to turn off the "Password Protection Sharing" feature, because if it is enabled, it will also force the shared connection to authenticate. Turning off the "Password Protection Sharing" feature is very simple, we can click "Start" /"Settings" /"Control Panel", select "Network and Internet", "Network and Sharing Center" one by one, at the sharing and discovery location Expand the "Password Protected Sharing" setting area, select the "Turn off password protected sharing" option, and finally click the "OK" button.
