Intranet access Baidu slow and packet loss serious

Years ago found in the visit to Baidu when the Web page does not open or unusually slow phenomenon, at first thought is occasional situation, also no one reflects, after a few days to find or there is this kind of situation appears, so contact the telecommunications ISP assistance processing, because my side has two lines of telecommunications, only access to the region of different bandwidth, a problem, An abnormal phenomenon, according to the telecommunications technician to find their line is normal, because all of our clients are DHCP to obtain IP and DNS address, but the DNS address is the IP address of the internal domain controller, they recommend that we manually configure a telecommunications public network DNS to test, Through the test found to improve, and then doubt whether the DNS settings caused by the problem, through the Nslookup test found that we resolved to the Baidu IP for a Hong Kong IP, the two lines are the same resolution, but the other line access is normal, and then into a dilemma, At this time, the technical personnel of the telecommunications prompt US whether the domain-controlled DNS Set forwarding address problem, through the Discovery domain control DNS forwarding address for the Singapore address, the basic judgment is a problem, so change the forwarding address for the local ISP DNS, through the test client discovery, All resolved Baidu's IP is the mainland's Baidu server address, and the access speed and ping packets are normal.

This troubleshooting let me on the domain control of some basic concepts have a deep understanding, because long time on the domain control does not have too much contact, so the emergence of problems can not quickly determine the point of entry, Welcome to 51cto friends to the domain control of the wrong opinion.
