@Dave Patrick Hello, the actual situation is: when I execute the gpupdate /force command on the secondary domain controller, it prompts an error that the policy file in the sysvol directory cannot be obtained from the primary domain controller server. I compared the sysvol directory of the two hosts, and there are indeed some files missing. I tried to manually copy the missing part of sysvol in the form of accessing the share through the domain name. The policy can be updated normally for the time being, but the sysvol directory of the two hosts is still not synchronized after the modification.
