How do I install an enterprise LAN? How do I connect to my company s LAN?

Hardware devices typically required for enterprise LAN installation: firewalls, routers, switches.

Depending on the number and distribution of computers in your enterprise. Make a suitable cabling scheme.

If it's just for aesthetics, you can put it on the edge.

When wiring the cable rack and network communication equipment (switches, routers, firewalls) should be placed in an independent computer room, the network cables should be classified by groups and labeled on the network cables for future maintenance.

If you are a small business, it is recommended to use a star topology (stable) firewall at the outermost, followed by the router, and then connect the switches.

As for what model and which manufacturer, you can consider it yourself, otherwise someone will blame me for saying good things about such and such a manufacturer.

Generally, if you buy equipment, the equipment manufacturer will also send someone to do wiring and equipment configuration, as for you, you can stay in the company to do technical maintenance in the future. If necessary, contact the equipment manufacturer to solve the problem.

Buy a router, switch on the line. The hardware is basically able to access the Internet. Pull the cord directly. The maximum network cable should not cross 100 meters. ADSL is connected to the roadfinder and then dialed the Internet with AppOE and entered the username and password.

1. Click the "Start" menu on the computer, and select "Control Panel" in the pop-up menu.

2. Click "Add or Remove User Accounts" from the list under "User Accounts and Family Safety".

<>4. Then under the "Change Account" directory, click "Create Password".

5. Then in the "Create Password" directory, enter the same password twice in the password box, and click "Create Password", so that the password creation is completed.

6. Now we go back to our computer, reconnect to computer B, enter the administrator name administratort and password, and then check "Remember my credentials", and then click "OK".

7. In this way, you can connect successfully, and you can connect to the printer and shared folder of computer B.

Step 1: Set up sharing

1. In order to determine the address information of the LAN shared computer, you first need to set the computer user name to facilitate searching.

2. Set the fixed IP of the computer, do not set the dynamic IP, and other computers in the enterprise can find the shared location of the computer through the IP. Open Network Neighbors, select View Network Link, and right-click to view local connection properties. Double-click to open Internet Protocol.

Set a fixed IP, the IP range is set by the router.

3. Set the local disk properties that need to be shared by the machine, take the D disk as an example, right-click to select Sharing and Security, check the two options in Network and Sharing, and set the firewall to the off state.

4. Use other computers to access the LAN to share the address of the computer to test whether it can be linked, enter the IP address in the start of operation to see if it is opened, and if it can be opened, the configuration is correct and does not need to be modified. If it cannot be opened, refer to Step 2 to adjust the settings.

Step 2: Adjust the settings

Problem 1: Prompt: Inaccessible. You may not have permission to use network resources. This is due to the restriction on guest accounts on shared computers, which can be removed as follows. According to the order of the arrows, delete the guest account at the end.

It depends on how much information the company has and what requirements it has to meet.

1. Set up an intranet. If dozens of computers are connected together with a Layer 2 switch or even a hub, and the IP is matched, it is a small LAN cavity high network with a short answer. If there are more than 100 VLANs, Layer 3 switches are required to divide VLANs to facilitate management and suppress network storms.

2. Control the Internet on the computer. Now it is generally set up on the firewall, which is the last exit for the computer to connect to the external network. In the firewall you can configure those IPs to allow connections to the Internet, those IPs cannot.

If the company is small and does not have a firewall, you can do MAC filtering on the router to control it.

3. Internal management of LAN, domain server can be built to achieve management.

Whether it is switch configuration, firewall configuration, or domain management, there is a deep knowledge in it, which needs to be studied diligently.
