How to solve enterprise network problems?

The 2M civilian ADSL bandwidth drags 100 machines, which is obviously too much. It is recommended to add at least one more ADSL access or switch to 8 Mbit/s enterprise-class broadband.

If the company allows the use of QQ and MSN software, it is more likely to lead to network congestion during peak hours. In particular, Tencent's own super whirlwind** tool is used under 2M broadband, as long as 2 of the computers open the **task, the entire network will be paralyzed.

Some routes or switches have the IP traffic restriction function, so it is recommended to use such devices to reasonably distribute network traffic.

Also pay attention to whether some calculators are infected with the ARP virus. APR viruses can spoof as gateways or DNS servers, making the entire network extremely unstable as soon as an infected computing is connected to the network. It can be monitored and inspected using the APR Kill Tool.

This is very likely to be related to the fact that someone in the network uses Thunderbolt, flashget and other software in **, or someone is watching online movies (network**), which will occupy a lot of network resources (that is, network bandwidth), when the occupied network resources are close to the total bandwidth of ADSL, there will be a large ping value, and even packet loss.

The network is unstable and does not hang msn, which has little to do with qq, and these 2 do not occupy any bandwidth.

First of all, if there are more people using it, the bandwidth of the network will not be able to bear it, and the wind speed will be slow! I guess that's definitely one of the biggest reasons!

And then secondly, your network topology planning, I don't think it's very well planned! Leads to a lot of radio storms inside! If the network of 100 information points does not pull a special line, I would like to ask you!

It's a few megabytes of pulling.,If you want to be faster, the minimum minimum can't be less than 5m!And then what model of router is it? What about processing power?

What about the backplane bandwidth of the switch? These are the causes of slow networks! It's nothing to do with MSN QQ!

Consult the master The network is abnormal in the company.

1.Hardware problems: If the network cable of the computer is aging or the router or cat is faulty, the network will be unstable, and you can replace these devices or contact the local broadband operator to solve the problem. 2.

If the computer configuration is too low or use this very old computer configuration, there may be a situation where the network speed is too slow or unstable, if this is the reason, then it is recommended to replace the computer configuration. 3.Trojan virus Trojan virus will disguise as a plug-in of computer IE, which will seriously affect the network speed, and it is necessary to upgrade the antivirus software to the highest level, and then carry out a comprehensive investigation and killing of the computer to effectively solve this problem.

4.Network card failureThe network card we use is generally a PCI network card or an onboard network card, and the better quality must be selected when choosing the right one, otherwise it may cause poor Internet quality. Then plug the NIC socket back in.

5.If the service operator's network is unstable, then it is useless to set it up. So make sure the server is stable first.

6.The presence of loops on the network is also one of the reasons for the slowdown of the network. Because when some more complex networks are used on the network, there are more nodes, which will inadvertently cause loops.

At present, there are ...... protocol viruses in the intranet, such as ARP spoofing, skull, CAM attack, IP spoofing, fake IP, fake MAC, IP fragmentation, DDoS attack, large ping packets, malformed data, and excessive packet frequencyA series of intranet attacks can cause intranet disconnection, stuckness, and slowness. Even attacks like ARP are not easy to detect, and antivirus software can't solve them, and they can't do it. This is also the main reason why the intranet disconnection cannot be solved after the system is reinstalled.

These intranet attacks are prevalent in the network. There is no good way to get rid of these problems directly.

At present, you can completely solve the problem of immune wall technology, and deploy immune network solutions through immune wall technology. Immunity network solution, you don't need to make major changes to your network, you can use the immune wall to set up a policy, do not install a driver, do not let the Internet, and intercept it when it is installed. It can directly intercept the virus attack sent by each computer from the network card, carry out unified management, there is only one network administrator, and it can also monitor the Internet access status of the entire intranet computer, and accurately locate and alarm if there is an abnormality.

Enterprise network problems are mainly to solve the interaction problem, for example, your network is interactive, three-dimensional, real-life, vivid, and dynamic. I recommend you to check out the interactive world network, their network is the latest dynamic network in the world, please click on their business team to help you solve related problems!

1. If you don't go to the Great Wall, you will be a good man.

2. The exhibition location is small, the scale of the enterprise is large, and the sales performance of the "dynamic scene exhibition" has risen.

3. People in Wenzhou in different places "buy a house" like the dynamic network to see the house remotely.

4. The college entrance examination is online "Jackie Chan" and the famous school is favored.

5. There are many Chinese furniture brands and it is much easier to choose dynamic scenes.

First understand your company's bandwidth access situation, and then check your company's usual traffic situation, if your company's employees use software such as P2P terminator, then you have to do IP-MAC binding. Case-by-case analysis.

Here's the solution:

1。If the company has other computers to access the Internet, find a switch and assign one to you.

2。If the company has an extra switch port, you can get on it by slitting the network cable from that port. The premise is that you don't have any other settings in the router...

3。The company doesn't have a computer with Internet access, so you can only pull a network cable or buy a wireless Internet from the wire.

4。Plug other network cables into your computer to see if you can access the Internet, if you can access the Internet, it means that you only need a network cable, you can refer to 1,2,3.

5。If you have a local connection to the company's network, you can access the Internet, dial in and let the router dial for you!!

A 150-meter network cable will definitely not work, at least I haven't seen a 180-meter cable.

It is recommended that you still use the fiber optic connection honestly at 150 meters or add a repeater to the twisted pair.

Put the switch near the telecom router, try it with a shorter cable, if it still doesn't work, then you need to consider the standard of the cable, whether to use a crossover cable, and many advanced routers and switches need to manually enable the port.

It is estimated that the IP address is bound to a MAC address. If you can access the Internet on your laptop at home, you can use the router to set your computer's IP to try, if this doesn't work, clone the MAC address in the wireless router to your computer's MAC address.

If DHCP is enabled for the router, the computer automatically obtains the IP address).

To clone the MAC address of the router into the MAC address of the computer, you need to find the physical address of the network card (that is, the MAC address) of the book.

1) Find the physical address of your NIC.

Enter the msdos mode of the system, issue the ipconfig all command, and you can find the MAC address of the computer network card. For example: 00-50-8d-d1-71-a7. Write it down.

2) Set the route (the wireless router is set to the machine IP, and clone is the machine MAC address, remember to leave the dormitory, be sure to go offline, otherwise the laptop will not be used when you take it home, and the IP address conflicts).

1) Restore the router to factory settings.

2) Normal routing dial-up settings.

3) Click the Network Parameters button in the left window of the route configuration page, and select the MAC address clone button. The window of "MAC address cloning" appears. In the window of "MAC address of the current management PC", fill in the "Valid MAC address" found above.

Click the "MAC Address Clone" button, and the MAC address will be filled in the "MAC Address" window. Save the settings. Exit the route settings, restart the route, and you should be fine.

Buying an online behavior management software can quickly and effectively control it. Disabling mobile devices and installing software to modify the options in the registry is fine.

1.Each computer must be configured to join the domain. Configure the "Computer Name" attribute in "My Computer".

2.In fact, it is not possible to prohibit logging in to the machine. The solution is to delete all the users, keep only the administrator user, and then set a password that the administrator knows.

3.Permission to install software can be restricted through the domain's Group Policy.

4.Your connection is the connection of the NAT gateway, ** Internet access does not require dual network cards. Do you want to ** or NAT?
