Lost local connection in xp/2k3 network neighborhood

1. The NIC driver is damaged or the NIC is in contact. Take a look at the status of the network card in the device manager, reinstall the network card driver or remove the network card to clean the slot.

2. Service status related to local connections: NETWORK CONNECTION and REMOTE PROCEDURE CALL, and PLUG AND PLAY.

3.DLL file not registered: service dependency prompts no INTERFACE registration category, new connection "prompt memory and hard disk space is insufficient", then re-register netcfgx.dll netshell.dll netman.dll three files , restart.

4. The system can't access the Internet after the system is in standby, mostly the power setting problem: Device Manager - Local NIC - Power Management Options, remove " Allow the computer to turn off this device to save power".

5. Check if it is set to delete the old connection: gpedit.msc Expand “User Configuration"—“Windows Settings”—“Internet Explorer Maintenance”—“Connection&rdquo ;, in the sub-window to the right of the "Connect" folder, double-click the "Connection Settings" option. Remove the following " delete the checkmark of the existing dial-up connection settings ".

Registration Command: regsvr32 DllFile

Refer to the following:

No local connection or loss of local connection is a common computer failure, there is no local connection, there is When you can access the Internet normally, sometimes we can't access the Internet. In other cases, you need to change the IP settings, but you cannot find a local connection. This article illustrates the solution to the loss of these local connections from the simplest methods and diagrams. I received a copy of the book today, without a local link, and it took a long time to process. So I want to write it for future reference. If you can use it, I am very pleased. The order of the solutions is from easy to difficult. If you can't solve your problem from the top down, sorry, it is estimated that the hardware interface or motherboard chip is faulty. It is recommended that you get professional customer service.

One, the taskbar does not have a local connection and the right-click "Network Neighborhood" & ldquo; attribute & rdquo;

This is the most simple local connection is lost, and in fact, that in fact it is more is lost accidentally set to hide, or set it to modify the virus.

Solution: Right Network Neighborhood & mdash; attribute & mdash; will open the Network Connections window, right & ldquo; Local Area Connection & rdquo; & mdash; & ldquo; Properties & rdquo; & mdash; see the figure below, both the hook hook marked, click on the & ldquo; OK & rdquo; on OK.

Second, you can't see the local connection anyway.

This is a more complicated situation. We are divided into several steps to check. It may be caused by poor hardware contact, or driver error, or service is disabled, or system policy settings. Let's take a closer look at each of the solutions.

1. Plug and unplug the network card once

If it is a separate network card, the loss of the local connection is mostly caused by poor contact of the network card. The reason is that the host is shaken or not cleaned for a long time. And caused poor hardware contact.

Workaround: Shut down, unplug the power plug at the back of the mainframe (very important), open the mainframe, remove the patched screws on the NIC, and carefully unplug the NIC. Use tools to clean the motherboard dust (preferably with a hair dryer), especially to clean the slot of the network card, wipe the layout of the network card with a dry rag (must be dry), and then wipe the metal contact piece with rubber. Plug the network card into the original position, plug in the power, and start the test. If the local connection icon is found normally, the chassis is sealed.

If there is still no local connection, try again. If it still doesn't work, it is probably a problem with the network card. Try to find one or buy a network card to test.

2. View the status of locally connected devices in Device Manager

Right'My Computer”—“Properties”—“Hardware”—“ Device Manager & rdquo; & mdash; look at the device list at least one of the "network adapters", as shown below, if it is empty, it means that the system does not detect the network card, right click on the icon of the small computer "ld"; scan Detect hardware changes & rdquo;, check if it is still not a hardware contact problem or NIC problem.

The corresponding network card in the right-click network adapter selects <;Properties>; you can see the following figure, where you can see the status of the network card, including status, driver, interrupt, power control, etc. .

If you find that the prompt is not working properly, you can try uninstalling the driver and restarting the computer. Or unmount the driver, unplug the network card, change a slot, and restart the computer. Since the system will re-detect the hardware, if it is not a hardware failure, the local connection here will generally be normal.

3. Loss of local connection caused by service process

Some friends who accidentally disable certain services may also lose local connections.

Solution: Right & ldquo; My Computer & rdquo; & mdash; & ldquo; management & rdquo; & mdash; & ldquo; Services and Applications & rdquo; & mdash; & ldquo; Services & rdquo ;, find & ldquo; Network Connections & rdquo; double-click, The following picture will appear

Please note that the “Startup Type” and “Service Status” are not mandatory for the startup type, if you feel unsure. Change it to “automatic", it is important to "service status", be sure to "started". If you can't set it here, please first change the "disable" in the “startup type" to “auto" or "manual", others will be modified.

We will see the "Dependency" button and will see "Remote Procedure Call (RPC)". So, look at the status of the “Remote Procedure Call (RPC)” service, making sure it also “automatic” and “already started”. Hint: There is also a “Remote Procedure Call (RPC) Locator” service that is not set.

We have already set up the service, so if we don't do it, we will set another important service as normal. Plug and Play This is the so-called "Plug and Play" detection service, of course, in accordance with the settings we mentioned above.

After the setting of the service process is completed, right click "My Network Neighborhood" & mdash; & ldquo; Properties & rdquo;, see the window of the network connection, refresh several times, see if there is any effect, it is not possible, restart once. If the local connection caused by the system service problem is lost, such a setting can be solved.

4. Check if the existing connection is deleted

“Start”—“Run”—Enter gpedit.msc Click “OK", and then expand“ User Configuration & rdquo;—“Windows Settings”—“Internet Explorer Maintenance"—“Connection"> In the sub-window to the right of the “Connection” folder, double-click “Connection Settings&rdquo ;Options. Look at the two figures below.
