as everyone knows , Computers need to add domains , Must be able to correctly resolve the domain name , But the customer said , New computer ping The domain name is displayed as the public network IP, As a result, the computer cannot add domains . Hearing this question , The first reaction was DNS The problem of .
Is it DNS Server The problem of , Or computers DNS Client The problem of , It's actually easy to judge , Just another computer ping The domain name can be normally resolved to the intranet domain controller IP, said DNS Server No problem at all .
Due to the initial setting IP At the address , Set up 114.114.114.114 As DNS The server , So guide the customer to modify it to internal DNS The server IP after , perform ipconfig /flushdns command , To refresh DNS cache , But it doesn't work .
Log in remotely to the customer's new computer , Find out IP and DNS The server configuration is correct ,ping The domain name is still displayed as a public network IP.
Immediately thought of , Maybe this computer adopts IPv6 The protocol is in communication , And Intranet DNS The server is not configured IPv6, It should be through the router , Directly resolve to the public domain name , So the IPv6 After the agreement is removed , determine .
Say it smoothly , Because this computer has dual network cards , So the gateway is not filled here , In fact, it will not affect the domain 、 Access network drive and other operations , Don't be surprised .
here ,ping The domain name is displayed as intranet domain controlled IP, Operation adding domain succeeded .
Actually , This is a small problem , I went online to solve the problem , That is, twenty or thirty seconds , But some network managers will walk into a dead end , I always think it is DNS Server failure , Or don't know where to start , So I hereby share .
