Windows Server R2 Setting NTP service

In fact, and the previous version of the server configuration is nothing different

Change the registry first:

Hkey_local_machine\system\currentcontrolset\services\w32time\config\

Set AnnounceFlags to 5

Hkey_local_machine\system\currentcontrolset\services\w32time\timeproviders\ntpserver\

Set Enabled to 1

Then restart the service (in fact, the win server12 default is not enabled W32Time service ... ）

net stop w32time net start W32Time

Finally join the firewall rule, open port 123, command prompt:

Add portopening protocol = UDP Port =123 name = NTPSERVER

Then the terminal can be set to sync

Recommended terminal modification under time interval, registry:

Hkey_local_machine\system\currentcontrolset\services\w32time\timeproviders\ntpclient

SpecialPollInterval default = 604800 = 7 Days * 24 hours * 60 Minutes * 60 seconds (i.e. the default is one week synchronization)

Change to the time that you think is appropriate

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters

NtpServer To synchronize the time service source, you can directly change the registry to specify (not necessarily to be set in the Control Panel, in fact, the two effects are the same)

 

Hkey_local_machine\system\currentcontrolset\ Services\w32time\config

MaxNegPhaseCorrection indicates that if the network time is faster than the local time, the number of seconds will not be automatically corrected

MaxPosPhaseCorrection Indicates that if the network time is slower than the local time, more than this number of seconds will not be automatically corrected

To set the value to FFFFFFFF (hexadecimal)

for each bound correction
