This article introduces all kinds of application skills of local connection under XP, the content is very detailed, interested friends can refer to it, I hope it can be helpful to you.

1. Click start, open "run" and type "gpedit.msc" in the run bar. Then OK, Group Policy is opened.

two。 Click "Administrative template" under user configuration-Network-Network connection.

3. Change "disable access to LAN connection properties" and "enable windows2000 network connection settings for administrators" to enabled.

4.OK, look again that your local connection properties have become grayed out.

In the Windows 2000/XP/2003 Server operating system, there are three dynamic link library files (Netcfgx.dll, Netshell.dll and Netman.dll) related to network functions. As long as you log out of these three files, you can block the Network connection window and prohibit the modification of IP addresses through the Local connection Properties dialog box.

1. Click the start → run menu, enter the command "regsvr32 Netcfgx.dll / u" (text in double quotes only) in the Open drop-down text box, and click OK. If the execution is successful, a prompt message is displayed.

Note: a space is required between regsvr32 and Netcfgx.dll and between Netcfgx.dll and / u in the command.

two。 Replace Netcfgx.dll with Netshell. Dll and Netman.dll can be repeated.

In the future, whether you click "Properties" in the "Network neighbors" right-click menu, or double-click the "Network connections" icon in the "Control Panel" window (the icon has actually changed), you will not be able to open the "Network connections" window, so you cannot modify the IP address through the "Local connection Properties" dialog box.

If you want to restore the ability to modify the IP address, simply delete the "/ u" parameter in the above command and execute it again.

Method 1: as the local connection icon is related to the system's Netcfgx.dll, Netshell.dll and Netman.dll dynamic link files, once the three dynamic link files are unregistered, then the local connection icon will be automatically hidden. When unregistering the above three dynamically linked files, you can first open the system run box and enter the string command "regsvr32 Netcfgx.dll / u" command to restore the regsvr32 Netcfgx.dll / s

Method 2: 1 Open the running dialog box of the system and execute the "gpedit.msc" command. In the pop-up group policy editing window, expand "user configuration", "Administrative templates", "Task Bar and start menu". In the right sub-window corresponding to "Task Bar and start menu", double-click the "remove Network and Dial-up connection" option from the start menu. In the pop-up interface, select the "enable" option. Click the OK button again, and you will OK.

Method 3: run msconfig to shut down the Network Connections and Workstation in the service (usually this is OK). After restarting, the prompt is missing a service regardless of

Three ways to protect the IP address in the LAN

The IP address in the local area network is occupied or tampered with from time to time, which provides you with several practical tricks.

Deactivate the network connection service

The easiest way to restrict users from arbitrarily modifying TCP/IP parameters is to prevent users from opening the TCP/IP parameter settings window. Open the "start" run enter "services.msc" command, select the "Network Connections" service, right-click, select the deactivate button from the properties, select "Startup Type" to "disabled", and make sure. In this way, if you enter the "Network connection" from "start", you will not find the "Local connection" icon. This will also bring trouble to the modification of your network parameters. You can disable the "Plug and play" service so that your normal network access will not be affected.

Method of limiting modification of network parameters

It can be realized by modifying the relevant network key values of the registry. Enter the "run" input "regedit" command, open the registry to edit, make sure that on the HKEY_USERS\ DEFAULT\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ Network branch, in the right area, select the "Edit", "New", "Dword value" options, name the new Dword value as "NoNetSetup", enter its value as "1", restart the computer, and the system will prompt you not to enter the network properties settings window.

Hidden local connection icon method

The local connection icon is related to the system's three dynamic link files: Netcfgx.dll, Netshell.dll and Netman.dll. Once these three dynamic link files are unregistered, the local connection icon will be hidden automatically. When unregistering the above three dynamically linked files, you can first open the system run box and enter the string command "regsvr32 Netcfgx.dll/u" in it. After clicking the "OK" button, you can unregister the Netcfgx.dll file.

Delete local connections hidden by the system

Due to the failure of the machine's network card, after replacing the network card, the system found new hardware on its own-it was reported that a new network card was found, and the system automatically installed the driver. After installing the driver, it is found that there is no "local connection" icon in the network connection, only a "local connection 2" icon. When setting the IP address of Local connection 2, the system prompts that the IP address has been occupied by a hidden network card.

Since Windows XP does not need to start to install new hardware devices, when there is a hardware update, the original hardware information of the system will still exist, and we must manually clear the hardware information by modifying the registry. To remove hidden network cards in the system, we must run regedit to open the registry editor and find the HKEY_LOCAL_MCHINE\ SYSTEM\ CurrentControlSetControl\ Network\ {4D36E972-E325-11CE-BFC1-08002BE10318} "key.

Information about the local connection is stored under the subkey. There are one or more subkeys, of which the first subkey corresponds to the "local connection", the second subkey corresponds to the "local connection 2" and so on, we can also expand the subkey, and then select the following "Connection" subkey, in the right window will see the specific is corresponding to which connection, directly corresponding to the previous connection of the entire subkey can be deleted.

After modifying the registry, restart the computer to set the network card correctly.

Bring the Local connection back to normal

Whether we are connected to the Internet or the LAN, we need to start with the "local connection" and configure the network parameters appropriately. However, in the actual process of surfing the Internet, we sometimes find that a variety of inexplicable failures may occur in the "local connection". These failures often cause us to be unable to set the network parameters pertinently, thus affecting our Internet efficiency. In order to effectively improve the efficiency of the Internet, we must master some troubleshooting methods related to the "local connection". This is not the following list of several fault phenomena that are more likely to occur in the "local connection". And put forward different ways to deal with each failure phenomenon, I believe it can bring you a harvest!

Resolve Local connection restricted Failur

Under the Windows XP SP2 operating system, some ADSL users often use the PPPoE dial-up method built into the Windows system when dialing the Internet; however, when using this method to surf the Internet, these users may find the display status of the "local connection" icon in the network connection list window, which is often inexplicably adjusted to "restricted or unconnected", but the Internet operation can be carried out normally in this state. So how does this strange state show that the fault occurs, and how can we eliminate it?

If the display status of "Local connection" becomes "restricted or connectionless" for no reason, this is usually caused by not assigning a fixed IP address to the network card. Under normal circumstances, when we find that the display state of the "local connection" is abnormal, we can often try to set a static IP address for the network connection first. This method can often solve a lot of inexplicable network problems for us. Once we find that the local network connection does not use a fixed IP address, we can click the "start" / "Settings" / "Network connection" command. In the network connection list interface that appears, right-click the "Local connection" icon, execute the "Properties" command from the right-click menu, and open the property settings window for the local connection. On the General tab page of the window, select the Internet Protocol project and click Properties.

About the local connection under the XP how the various application skills are shared here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
