Phenomenon: The company's entire network has slowed down, the workstation is very slow, the landing area takes more than five minutes, after entering the desktop, open the server sharing file is slow, the speed of online printing is more unbearable.
Reason: Unknown, still thinking about it so far, I don't know why suddenly slowed down, I didn't change any configuration before, I used to be related to the configuration of the machine, is there.
Solution process: I have done a lot of work, overtocal until 4 am in the morning. First back up the data, re-configure the operating system, configure it three times, because there is no setup to computer name and domain, the company's computer name is NTServer, the domain is HWSERVER, the configuration process first should set the computer to NTSERVER. Then, the AD configuration is performed, and the domains and NetBIOS names that are required to be entered, and the NetBIOS name should be HWServer.com and HWServer. After the service was configured, the next day was still very slow, so the Internet is found, and finally, after seeing an article, the problem is finally resolved, first point a DNS of the workstation to the service IP, if the result is a speed change Fast, and on the Internet is unstable, the second step is to open the server DNS and will be "." To "." Under the search area, because "." Represents this server is the root server, so there is no DNS automatic steering function. At this point, this fault is resolved.
