There was no intervention in the implementation of the project, and some pits were found in the later stage of operation and maintenance. The project uses two servers as domain control servers to enable AD DS,DNS,DHCP services. After configuration, it is found that users are particularly slow to access the Internet, and some users are unable to obtain IP addresses. It is initially determined that it is the problem of DNS and DHCP services. Upon inspection, it is found that DNS is not configured for forwarding, only some address resolution of the intranet is configured. Open the DNS manager, properties, transponder, with 114and Ali's dns, the Internet problem is solved.

Later, check the DHCP service and find that the configuration of the two sets is the same, but no failover is configured, so do it. (reference link)

And one of them is not authorized, the DHCP service has a disable flag (down red arrow). (reference link)

Open "DHCP". In the console tree, click DHCP. On the actions menu, click manage authorized servers. The manage authorized servers dialog box appears. Click authorize. When prompted, type the name or IP address of the DHCP server you want to authorize, and then click OK.

After the match, there are basically no problems on the Internet.
