How to set up online neighbors * * *

Do you know how to build online neighbors? We can create multiple users for the computer. What is enjoyed here can also be enjoyed by users who use this computer. You can let users who want to enjoy * * * set their operation permissions. Let's take a look at how to set up online neighbors * * *, welcome to check!

How do I share files with my online neighbors?

The ways to share files with my online neighbors are as follows:

1, we click on the network to open the network interface.

2. After we open the network, the system will pop up "Network discovery and file sharing closed." . I can't see the network computers and devices. Click to change ... "... which means we don't have network discovery turned on. Then we click on the tip above.

3. Click the prompt to pop up the selection box, and we click to enable network discovery and file sharing.

4. Then a dialog box like this will pop up. We click Yes, enable network discovery and file sharing for all public networks.

5. Next, we click the network icon in the lower right corner of the desktop, and then click "Open the network and enjoy the center".

6. We click on the network to be set.

7. I clicked on the work network here, which I chose according to myself.

8. After selecting, we click Close.

9. Then we go to "Network and * * * Enjoy Center" and click "Change advanced * * * Enjoy Settings".

10, and then we click Modify Settings, and I'll give you a screenshot. Set according to the figure below.

1 1, Media Stream can be set according to your own needs, and others can be set according to the following figure.

12. Finally, we click "Save Changes" so that our Windows 7 online neighbors can enjoy it.

Online neighbors * * * enjoy how to build a tutorial.

Details are as follows:

1. Right-click My Computer and select Properties. In the open properties, click the computer name to see the name of the LAN workgroup that appears in this tab. If the working group names are inconsistent, it will lead to the phenomenon that online neighbors can't open it.

2. Open the guest account: right-click my computer, and there is a guest account in the administrative user. Double-click this account and remove the check mark before "Account Disabled".

3. Install the mobile protocol protocol compatible with NWLINK IPX/SPX/NET BIOS.

4. If the WinXP firewall is in the default setting state, it means that all the network connections of the computer are running, and it is difficult to realize the enjoyment of online neighbors. At the same time, because Windows firewall prohibits "files and printers * * *" by default, enabling the firewall limits the * * * sharing problem of LAN. The solution is: enter the local connection window, click Advanced-Settings-Exceptions, and check "Enjoy files and printers * * *" under programs and services.

5. Delete the guest account in the item "Deny access to this computer from the network": Start-Run the "gpedit.msc" command to open the group policy, and the local computer will configure windows settings, security settings, local policies and user rights assignment to deny access to this computer from the network. Delete if there are guests. (The reason is that sometimes xp visitors are not allowed to visit * * *).

6. Cancel the mode of "Enjoy with Simple Files * * *": check the folder option of the Explorer tool and remove the check before "Enjoy with Simple Files (Recommended)".

7. Check "Microsoft network files and printers * * *".

8. Run the "Services.msc" command to open the service policy. Start the Folder Server: This service allows other users on the network to view your folders. Of course, sometimes you can start it manually and then use other programs to publish information on your network.

The above is the solution to the online neighbor blank in xp system. Users who need it can solve it according to the above operation method.

Online neighbors * * * enjoy knowledge

Speaking of "online neighbors", I believe many people are familiar with it. After installing the operating system, the only icons on the desktop include "My Network Places".

However, to talk about the working mechanism of "online neighbors", maybe everyone is not clear.

To talk about the working mechanism of "online neighbors", we need to contact examples in life: for example, I want to visit a distant friend-A, I want to go to his home, what should I do? The answer is to find A's home first, and then make sure to see if A will let me into his home. Don't think this is a joke. This is the working mechanism of "Online Neighborhood".

In a local area network, it seems logical that you can see all users in the network by double-clicking "Online Neighborhood" on the desktop. But have you ever wondered: How does Windows know the names and locations of these computers? How did it get their position?

Since Windows 2000, access through "My Network Places" is actually through browser services. Here are some key points of browsing service.

First, browse the list.

Browsing list is a key part of browsing service. Only through this list can Windows-based computers discover computers and service resources on the network. Browsing the list is like an address book, telling your computer where there are resources. Your computer will use the information in this list to resolve the computer name into an IP address and provide it for users to access.

So, where did the browse list come from? The correct answer is-the browse list is provided by the browse server through broadcast query.

Many times, computers in the network cannot update the browse list correctly. When the computer shuts down normally, it will send a broadcast notice to the network, so that the browsing master server can delete it from the browsing list in time; However, after the abnormal shutdown, the entry will remain in the browsing list for a long time, which may cause us to still see it but not access it in our online neighbors. You may think, where is the browsing server in our network?

Secondly, browse the server.

The browsing server was selected by election. The main condition for election is the operating system. In the experiment, it is found that windows 2000 professional has higher priority than windows xp. When XP is started first, it is a browsing server, but when 2000 is also started, 2000 will issue an election request, and eventually grab the identity of the browsing server in the election. We won't explore other conditions, anyway, the result is to select the main browsing server and the backup browsing server. There is only one main browsing server in a workgroup, and there can be multiple backup browsing servers. The computer that acts as the primary browsing server can also act as the backup browsing server.

When the computer starts, if its printing and file sharing functions are turned on, it will send out a broadcast package to register itself in the network. After receiving the broadcast, the main browsing server will add relevant information to the browsing list every once in a while and verify it, so we see this newly started computer.

The first time, this cycle is 1 minute, 2 minutes, 4 minutes, 8 minutes, and finally reaches 12 minutes, and then every 12 minutes, the client will send a notice to inform the main browsing server that "I am still here". If after three cycles (36 minutes), the main browser doesn't hear the notice of "I'm still here", then it will delete the name of this client from the browsing list, and there will be no more users in "Online Neighborhood".

If the network is large, if everything is done by the main browsing server, it will greatly affect the performance of this computer, so the browsing list we query is not from the main browsing server, but from the backup server. The main browsing server will periodically send the browsing list to the backup browsing server to update the browsing list.

In short, the process of online neighbor access method is: the client first broadcasts (UDP) the list of backup browsing servers, and the main browsing server notifies it, but only the computer name should be paid attention to. The client uses UDP to query the IP address of the computer name, broadcasts the same computer name three times, and then waits for the answer. If there is no answer, it will broadcast the computer name of the next backup browsing server (if there is one). After successfully obtaining the IP, the client will establish a TCP connection with the 139 port of the backup browsing server, and then obtain the names of other computers in the workgroup. When you open a computer, the client will query the IP of this computer through UDP. If no answer is given, the connection will be wrong. If you get the answer, then you have entered the stage of establishing a connection.

The above procedures use netbios protocol.

Third, NETBIOS protocol.

Netbois (Network Basic Input/Output System) was originally developed by IBM and Sytek as an API, which enables users' software to use LAN resources. Since its birth, Netbois has become the basis of many other network applications. Strictly speaking, Netbios is the interface standard for accessing network services.

NBT (netbios over TCP/IP) is a NETBIOS interface based on TCP/IP transmission protocol. Compare it with Nbf first. Nbf refers to NETBIOS frame protocol, which is based on NetBEUI. This is a real protocol based on link layer, but it can't be routed because it is in LLC (Logical Link Control Layer) layer. Only with the help of some routable protocols (such as IP or IPX) can we browse across broadcast domains. Because TCP/IP is the fastest developing and most popular, NBT has attracted so much attention. Now all windows systems use NBT. The services provided by NBT can be divided into three categories: name service (UDP- 137 port), datagram service (UDP- 138 port) and session service (TCP- 139 port). Now all windows systems support NBT protocol by default, but NetBEUI is useless (it seems that XP system is not installed by default), so it doesn't matter if online neighbors can't access it, so don't confuse it with others. NBT is a protocol used by online neighbors (system default). ?

1, name service (UDP- 137 port) is mainly used for broadcasting to solve the relationship between NETBIOS name and ip address translation of this subnet. Because NBT is based on TCP/IP, it is necessary to know the IP addresses of both parties to establish TCP/IP communication. However, because UDP broadcasting is used, the name service cannot cross the router.

2. Datagram service (UDP- 138 port) provides connectionless (UDP) and broadcast-oriented communication mode. It is mainly used to broadcast the query from the main browsing server to the backup browsing server list. Because it uses UDP broadcast, it will encounter the same problems as name service when crossing the router.

3. The session service oriented to connecting TCP protocol (TCP- 139 port) is used to query the backup browsing server to get a list of computers in a workgroup, and can also establish a data transmission channel for online neighbors under the 98 system.

Said the principle, let's talk about common problems and solutions:

Basic conditions for window neighbors to exchange visits;

(1) Both computers are turned on to set up network resources;

(2) The "Microsoft Network File and Print * * *" service has been added to both computers;

(3) Both parties have correctly set the IP address in the network and must be in the same network segment;

(4) Both computers have turned off the firewall, or there is no policy in the firewall policy to prevent online neighbors from accessing.

If your online neighbor has a problem, please refer to the following steps:

1, network cable. The interconnection of two computers does not use hubs or switches, but uses cross wires to connect the two computers; If a hub or switch is used, connect it to the hub or switch through a straight line to ensure that the status lights of the switch and network card are normal.

2.IP protocol. By default, the TCP/IP protocol will be installed on WIN98 and later machines, and WIN95 needs to be installed separately. Online Neighborhood-> Attribute (WIN9X/Me) or online neighbors->; Attribute-> Local connection-> You can check whether the TCP/IP protocol (WIN2K/XP) is installed in the property.

3.IP address. Set IP address, subnet mask and gateway in TCP/IP properties, and set DNS and WINS server addresses if necessary. Recommended IP address setting: 192. 168. X.X, subnet mask: 255.255.0. If you have a DHCP server in your local area network, just choose to get the address automatically.

Verification method: use ping x.x.x.x (the IP address of the other party) at the DOS prompt. If the following information is returned, the IP setting is successful:
