1, set up an intranet. If dozens of computers are connected by layer 2 switches or even HUB with IP, it will be a short and easy LAN. If there are hundreds or more, in order to manage and suppress the network storm, VLAN needs to be divided by three-layer switches.
2. Control the computer to surf the Internet. Now it is generally set on the firewall, which is the last exit for the computer to connect to the external network. In the firewall, you can configure which IPS are allowed to connect to the external network and which IPS are not allowed to connect. If the company is small and has no firewall, it can be controlled by mac filtering on the router.
3. Local area network internal management can be managed by building a domain server.
Whether it is switch configuration, firewall configuration or domain management, there is deep knowledge in it, which needs to be studied well. You can talk about the specific situation and requirements for everyone to learn.
Question 2: How to set up a small company LAN? Prepare a switch with more than 8 ports (tens of yuan).
Second, the number of network cables (depending on your field distance) (tens of dollars)
Third, a cat is about 100 yuan.
4. Router 100.
Connection:
Broadband line-cat-router (or three PCs can be connected)-switch-PC,
Settings:
Determine the IP address of the router first, and then fill in the IP address in the PC (for the same network segment, for example, the IP address of the rover is192.168.1,then your company's network segment is192+/kloc-0.
Settings file * * * Enjoy:
1) Install the nwlink IPX/SPX/NetBIOS Portable Transport Protocol.
(2) Open the guest account: right-click My Computer \ Manage \ Users have visitors, and double-click to remove the check in front of "Account Disabled".
(3) Right-click My Computer \ Properties \ Computer Name to see the name of the LAN workgroup that appears in this tab, such as Workgroup \ Network ID\ Next \ Select "This computer is part of a commercial network and use it to connect to other working computers" \ Next \ Select "The company uses a domain-free network" \ and then enter the name of the LAN workgroup, such as Just restart the computer.
(4) Exception of using the winxp firewall: By default, the winxp firewall is fully open, which means that it is difficult to enjoy the online neighbors by running all the network connections of the computer. At the same time, because the windows firewall prohibits "files and printers * * *" by default, it is often impossible to enjoy printing when the firewall is turned on. The solution is: enter the local connection window, click Advanced \ Settings \ Exceptions \ and check "Files and Printers * * *" under programs and services.
5) Delete the guest account in the item "Deny from Network * * *": Run Group Policy (gpedit.msc)\ Local Computer \ Computer Configuration \windows Settings \ Security Settings \ Local Policy \ User Rights Assignment \ 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 Simple Files * * *": Explorer \ Tools \ Folder Options \ View \ Remove the check in front of "Enjoy Simple Files * * * (recommended)".
7) The names of the working groups are consistent.
8) Check "Microsoft Network Files and Printers * * *".
9) Run the service policy "Services.msc". 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.
Question 3: How to join the company LAN? What I understand is that computer A is connected to the office LAN, and the original computer can enjoy the network printer, but only computer A can't? According to your screenshot, computer A has been connected to the LAN, and the IP, subnet mask and gateway obtained are all ok. But I think you should still PING192.168.1to see if you can ping the gateway. If the gateway can PING, there is no problem with the LAN connection.
Click start-run -\ \ c computer IP address on computer a-double-click the printer you want to add.
Question 4: How to build a company LAN! The main reason is that the landlord's request for * * * to enjoy some files is complicated, so it's hard to say clearly here. I only provide a plan, and the specific measures need your own efforts. First of all, you are not asking too much. Our company is more complicated than your design. 1, the head office and branches can exchange visits and use vPn function. This function can be realized by software or hardware, and the software win2003server comes with it. Need to buy hardware, ranging from a few hundred to tens of thousands. Please search vpn for details. 2. The access problem between companies is simply to set up a local area network, but if you set up complicated mutual access rights, it is better to use OA office system to set their access rights by restricting different login users, including network hard disk, chat room, filing cabinet and so on. 3. The office webpage is OA system, and the extranet is a single server. 4, employees can access the company's intranet at home, in fact, access the company's OA system, which can realize remote office. This requires mapping the OA server in the intranet to the external network. If there is a router, port mapping is needed, and the ports of external access routers are mapped to the ports on a specific computer, for example, 80 ports on the external network correspond to192.168.1.580 ports. Another necessary condition is that employees need to know the IP of the company, which can be accessed through IP, or they can apply for a free domain name and point the domain name to the IP. However, it is troublesome for companies without fixed IP, and it is necessary to change domain names frequently. Of course, you can also use a dynamic domain name system, such as peanut shells. 5. surfing the internet is easy. Just buy a router and set up a LAN. As for the public network address applied by each branch, there will be no more than five. I don't know what you mean, I can't answer. In fact, any of the above five can be talked for a long time. Here, I only give you a role of attracting jade. If you don't understand the news, a lot of knowledge needs to be answered by yourself. You'll never understand until you do it. Our company has 202 networks and telephone points, and it took more than 30,000 meters to set up a local area network, all of which I set up and managed by myself. The realization function is similar to what you said, and an intranet OA can be accessed externally. Support voice, video and external network access. Plug-in a website, 10 departmental local area network, so that different users can access the external network at different working hours every day, and different users may or may not use the software. There is a mail server, contact the national branch every day, and there is a forum, which belongs to the use of internal employees throughout the country.
Question 5: how to set up a local area network in the company, taking XP system as an example;
Connect a computer with a router or a switch (hub), and the workgroup settings are the same (the system usually defaults to workgroup), and then set the IP address of the computer to the same network segment (for example, if the address of the router is192.168.1.1,the computer IP is set to1.
Question 6: How to set up a company LAN? After 30 minutes, double-click "Network Neighborhood"-select "Set up a home or small office network" under "Network Tasks" on the left-there is an option "Enable file * * * to enjoy ..." After n "Next", continue to "Next"-create ING-create successfully-there are four options, and choose the last one.
Both computers should be built, and so should the working group. The default value is mshome.
Test: My Network Places-View Workgroup-Find another computer-Success
If you can't go online after successful creation, turn off the firewall of the host.
Question 7: how to set up a company LAN, install a network card for a computer with a printer, buy a router or hub,
Check the network cable from the second network card to the LAN port of the router or hub.
Other computers are linked to the LAN port of the hub or router.
If you buy a router, please set DHCP (convenient), and other computers are set to automatically obtain IP.
My computer properties changed the computer name and set the workgroup as the workgroup.
My computer properties service opens the workstation service.
It's done.
Good luck.
Question 8: How to set up such an enterprise LAN? Hehe, it's all advertisements. The landlord's request is complicated, so it's hard to make it clear here. I only provide a plan, and the specific measures need your own efforts. First of all, you are not asking too much. Our company is more complicated than your design.

5. surfing the internet is easy. Just buy a router and set up a LAN. As for the public network address applied by each branch, there will be no more than five. I don't know what you mean, I can't answer.
In fact, any of the above five can speak for half a day, and here is only one role for you. If you don't understand the news, a lot of knowledge needs to be answered by yourself. You'll never understand until you do it. Our company has 202 networks and telephone points, and it took more than 30,000 meters to set up a local area network, which I set up and managed by myself.
The realization function is similar to what you said. Intranet OA can be connected externally, intranet chat room supports voice and video, and extranet can be accessed. A website is externally connected with 10 departmental local area networks. Different users can access the external network at different working hours every day, and different users may or may not use the software. There is a mail server, contact the national branch every day, and there is a forum, which belongs to the use of internal employees throughout the country.
Question 9: How to build the local area network of our new company? Choose 24 *** switch and deploy it in wireless+wired mode. Only one wireless AP or wireless router needs to be deployed in the conference room (the network cable is connected to the wireless router and the routing mode is changed to switching mode). If each wired computer has a network cable, it can be wired with more than five types of network cables, and trunking or ceiling can be considered.
Question 10: How to create a local area network of the bureau company mainly explains the conditions for you to access the Internet, such as how to access the Internet, whether it is a private line or an AD, and whether there are routers, wireless routers, switches, etc. Originally, a server connected to the Internet could be used as a proxy server, but now this method is relatively rare, and the hardware connection is relatively stable. The server can be used as an intranet file server and a website server.
