The problem that the LAN cannot access the XP operating system

First case

1. First enable the guest Guest Account;
2. Control Panel → Administrative Tools → local security policies → Local Policies → user rights assignment, add a guest account to "access the computer from the network, and "Deny access to this computer from the network" to delete the Guest account;
3. My computer → tools → Folder Options → view → remove the check box before "using simple file sharing (recommended;
4. Set shared folders;
5. Choose "Control Panel"> "Administrative Tools"> "Local Security Policy"> "Local Policy"> "Security Options" and set "network access: the sharing and security mode of the local account is set to "Guest only-Identity Authentication for guests from the local user" (Optional). This setting removes the dialog box requiring a password for access, it can also be set to "classic-Local User Authentication ");
6. Right-click "my computer"> "properties"> "computer name". Does the tab show the name of your LAN Workgroup, such as "work. Click the "Network ID" button to start the "Network ID wizard": click "Next" and select "the local machine is part of the commercial network and connected to other working computers "; click "Next", select "company uses networks without domains", click "Next", and enter the name of the Working Group of your LAN, such as "work ", click "Next" again, and then click "finish" to complete the settings.
Generally, the above steps can be solved. If not, read the following link:

7. Check whether the local connection is disabled. Right-click "Local Connection"> "enable ";

8. Disable the network firewall;

9. Check whether the domain is enabled, whether the domain is added, and whether the domain settings are checked;

10. Check whether the server service is disabled;
11. Check whether the local connection IP address, subnet mask, gateway, and DNS settings are correct;
12. "Local Connection" → properties → General, check whether "Microsoft network file and printer sharing", "Microsoft network client", and TCP/IP protocol are installed;

 

Second

In our daily work, when we need to use resources on other computers from the Working Group of the LAN, click "Network neighbors", *, and a "network neighbor cannot be accessed, unavailable network. Sometimes you can see yourself in the network, but you cannot see others. Sometimes, you can't even see the "Network neighbors. Don't worry. Based on the specific analysis of different situations, you will find a satisfactory solution.
1. You can see yourself but not others.

The following problems occur:

1. Check whether the netbeui protocol is installed on the local machine and whether the "microsft network file and print sharing" service is installed. If not, refer to the demo provided by me (click to view the demo)

2. Line or hub Problems
(1) ping the IP addresses of other hosts and check whether the connection speed of other computers is normal. If the connection speed is normal, jump to step 2nd. Otherwise, perform the following operations.
(2) check whether the NIC prompt light on the chassis is flashing. If the light flashes, the connection between the local host and the hub is normal. Otherwise, check whether both ends of the network cable are plugged in and whether the power of the hub is on.
(3) check whether the indicators of ports on the hub and other computer ports are normal. If the connection is normal, the connection between the connected network device and the computer is normal. Otherwise, check whether the two ends of the network cable have been inserted and use the network cable tester to re-test the connection of the network cable.

3. Other computer problems
(1) check whether the NIC lights of other computers are flashing. If the NIC lights are not on, it may be that the NIC is not correctly installed or is not properly connected to the network connection device. Open "Control Panel" ---- "system" ---- "Device Manager" and check whether there is a "network adapter" or if the device under the network adapter has "?" Or "! ". If yes, delete the device, refresh and reinstall the driver for it. Program . If not, it indicates that there is no problem with the network device, or the network cable is faulty. Follow the method described in step 1st.
(2) If the protocol is installed, select "Control Panel" ---- "network" ---- "configuration" to check whether each computer is installed with TCP/IP and netbeui protocols. If no, add the above Protocol and delete the IPX/SPX protocol.
(3) Whether the IP address is set correctly. This check is especially important when you only select to install the TCP/IP protocol. In MS-DOS mode, run the ipconfig command to display the machine's IP address and subnet mask (subnet mask) and check whether the IP address is in the same network segment as other computers.
(4) Whether file and printer sharing are configured. Open "Control Panel" ----- "network" ---- "configuration" ---- "file and print sharing", check whether the check boxes "allow other users to access my files" and "allow other computers to use my printer" are selected. If not, select this option.
(5) Whether to log in as a user, whether it is a Microsoft network user, Microsoft friendly login or Windows login, the user name and password must be entered when the computer is started, if you log on to Windows 98 by clicking "OK" after entering the user name and password, and then clicking "cancel", it will not appear in the network neighbor. Check "start"-"deregister" to check whether there is a computer name after "deregister". If it is displayed as "deregister ......", It indicates that the user is not logged in as a user. Click "log out", restart Windows, enter the user name and password, and press OK to enter.
(6) Search for other computers. In "start" ---- "Search" ---- "computer", enter the name of another computer to search, or enter the name of another computer in "Resource Manager" ---- "tool" ---- "Search" ---- "computer". If everything is normal, you should be able to find the other party.
Sometimes the NIC configuration is normal, and the network neighbor can see himself (not to see others) and Ping himself. This is mainly because the NIC is not properly installed. (However, such NICs are generally old, such as the ISA interface ). Check the nic I/O and DMA Number:
1) Use the NIC in DOS to check whether the I/O and DMA of the disk are consistent with those in windows. Otherwise, change the configuration in Windows to dos.
2) Open the chassis and check whether the NIC jumper is set to auto mode. If not, change it to auto and then reinstall the NIC in windows.

In the LAN, you may often encounter a shared directory on a computer with Win2000, while a computer with Win98 cannot access the shared directory of Win2000. You can find the answer on Microsoft's official webpage, prompt to enable the Win2000 Guest user.

But after XP came out, it was the same problem. As a result, some people found that this method was not working. Accessing XP shared directories from network peers may not be allowed. Why? When the system Guest user is enabled, click Start> Run and enter gpedit. MSC, you can call up the Group Policy Editor, you can find a guest user in "Local Computer Policy \ Computer Configuration \ Windows Settings \ Security Settings \ Local Policy \ User Rights Assignment \ Deny access to this computer from the network! If you delete the Guest user here, other computers can view the shared directory of the computer from the network neighbors.

(Environment: Chinese WINXP, using traditional login methods and disabling "use simple file sharing" in "Folder Options ")

2. Neither you nor others

1. Check whether TCP/IP, netbeui, and other protocols are installed. (To add netbeui to WINXP, you must manually add the netbeui protocol from the installation disk.) Make sure that the "Microsoft Network File and file sharing" service is installed. If you are a Win98 user, you must set "√" in the check box before "allow users on the network to use my files and printers ".
2. Check the NIC Driver:

1) Right-click "my computer" or press win + break to open the System Properties window.

2) Click "Device Manager" and double-click "Nic. Check whether the installed Nic has a yellow exclamation point. If yes, it indicates that the driver of this Nic is faulty. Perform step 3.

3) Right-click the ENI name and choose "properties"> "upgrade driver". Then, follow the prompts to complete the operation step by step. At this time, we should be able to see at least ourselves on the network.

3. If you are a Win2000 or Win XP user, check whether you have joined the working group or domain in the LAN. If not, manually add it to "network and dial-up connections.

3. The message "unable to browse the network or access the network" appears.

The network is not accessible. There are several possibilities:

1. Check whether the network card and network cable connection are normal.

2. After windows is started, you must enter the Microsoft network user logon password and click "cancel. To log on to the NT server, you must log on with a valid user and enter the correct password.

3. Conflicts with other hardware. Open Control Panel → system → device management ". Check whether there is a yellow question mark, exclamation point, or red question mark in front of the hardware. If yes, you must manually change the device interruption and I/O address settings. To log on to the NT domain, you must also install the netbeui protocol. To log on to the NT server network, select "Microsoft network user" in "primary network logon" under "network ". To log on to the NT server network, double-click the "Microsoft network user" component in the "configuration" tab of the "network" attribute box, check whether the "log on to Windows Domain" check box is selected. Check whether the domain name under "Windows Domain" is correct.

4. Mutual access between window98 and Windows 2000/XP.

Many users once complained that Windows XP computers installed on the LAN cannot access each other with Windows 98 computers, windows XP and Windows XP cannot communicate with each other. I have seen a lot of tips from experts, which are summarized as follows: 1. Enable the Guest account; 2. Install the netbeui protocol; 3. Check whether the Guest account is disabled in the Local Security Policy settings; fourth, set the shared folder. However, even if we have done all these four points, we still cannot solve the problem of mutual access between Windows XP. To achieve mutual access in Windows XP, you need to set this step:

On the Windows desktop, right-click "my computer", select "properties", and click the "computer name" tab to see if your LAN workgroup name appears, for example, "tl2000. Click the "Network ID" button to start the "Network ID wizard": click "Next" and select "the local machine is part of the commercial network and connected to other working computers "; click "Next", select "company uses networks without domains", click "Next", and enter the name of your LAN Workgroup, such as "tl2000 ", click "Next" again, and then click "finish" to complete the settings. After the computer is restarted, computers in the LAN can access each other.

5. The computer name of the other party is displayed, but the other party does not provide shared resources. You can see the computer of the other party, but it is empty. What should I do with the stuff inside him? TIPS:

1. Double-click the computer name of the resource to be read in "Network Neighbor". This article takes "goodpc" as an example.

2. Enter "goodpc/ADMIN $" in the address bar. If you are lucky, you should be able to enter the computer of the other party. Next ...... This is mainly because the other party has not disabled "ADMIN $" "IPC $" "C $" "d $" and other empty connection sharing for access.
