Windows-NTP校時

w32tm有兩個地方可以設定，一個是registry，一個是policy(GPO)
registry可以用regedit開啟，位於
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time

policy用gpedit.msc可以開啟，位於
Computer Configuration\Policies\Administrative Templates\System\Windows Time Service

下面指令測試是否可以連線到NTP server

w32tm /stripchart /computer:time.windows.com /samples:5 

下面指令可以設定NTP server

w32tm /config /manualpeerlist:NTP.iead.local /syncfromflags:manual /update

w32tm /query /configuration
確認看到以下訊息，(本機)代表是從registry讀取的設定，(原則)代表是從 policy(GPO) 讀取的設定

NtpServer (本機)
DllName: C:\Windows\SYSTEM32\w32time.DLL (本機)
Enabled: 1 (原則)
InputProvider: 0 (本機)
AllowNonstandardModeCombinations: 1 (本機)

執行 regedit
