实战解析网络不能正常传输的五大原因（Actual combat analysis the network can not be normal transmission of the five major reasons） Actual combat analysis: the network can not be normal transmission of the five major reasons LAN in a long time after the operation, there will be a variety of strange and eccentric fault, which makes us the most headaches is the network transmission speed, even to slow stumbling cannot access the web content point, because with the rapid development of information technology, many units and employees are unable to leave the network once the network; the transmission speed of wobbly or even normal transmission, so most of the work unit or staff may be unable to carry out normal. In order to improve the efficiency of units or employees, it is very important to find ways to make the network transport unimpeded. Now, this paper from the perspective of the actual reasons, several normal transmission network cannot contribute to all the friends and the way to deal with, I hope you later encounter similar network transmission failure can inspire! Combat 1:DNS forwarding inappropriate, causing the transfer of the dead cycle Wang recently visited the Internet network from a workstation in a local area network, and found that the content of the web was very slow to display, and from time to time, there was a phenomenon that the web could not be opened. At first he thought it was his workstation system infected with a virus, but asked other colleagues, he found himself in a sub station and other network access outside the network speed is very slow, which shows that the problem with the network virus, the possibility is not great. Later, Wang contrast carefully examined several Taiwan Internet workstation configuration parameters quickly, see the DNS server address parameter is not the same, some units are using the primary DNS server address, or use the alternate DNS server address, LAN logically in two DNS servers should not appear at the same time fault! Wang? Som
