Made a domain environment of enterprise, the closed loop LAN, can not access the Internet, all clients set domain policy and the synchronization time domain controller, the domain controller because all don't have access to the network time synchronization source, result in the following circumstances, I'm not sure whether the reason lead to
1, often appear the alarm server log


2, seems to be the cause of the client can't sync, part of the abnormal situation, the client also each polling the time difference of client and server increases



Here is too little, because such on manual consult predecessors to give directions, thank!

Time synchronization is to network, and the other to do a network time synchronization server?

CodePudding user response:

If the conditions are not allowed to access the network time server data structures, the NTP server yourself

refer to the second floor of the nighthawk reply:

if the condition does not allow access to the network time server data structures, the NTP server yourself

Is to set up the NTP service in DC, DC cannot on the network, so its no external synchronization events, often appear the figure of a warning,

See, this problem is a bit like inception, the company does not allow any outside network connection right?

Strictly the environmental requirements, such as anti-virus, prevent leaks, etc., so just a network, provide the NTP service DC, its source and no time to sync, this alarm, don't know how to configure can be avoided, and the individual client also in figure 2 in figure 3 is unusual, polling log shows the time differences also increase gradually, follow-up and automatic synchronization with the server time returns to normal,

Suggested considering the NTP service configuration on the switch,
It is safer, then DC and switch synchronization time
