Windows NTP Setup
From Tech-Wiki
Registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
When the synchronization type is set to "NT5DS", Windows Time Service synchronizes its time resource with the network domain controller. Alternatively, setting the type attribute to "NTP" configures Windows Time Service to synchronize with a specified NTP time server. The NTP server is specified by either its Domain Name System (DNS) name or its IP address these are specified using the "NtpServer" value name.
To set manually:
w32tm /config /manualpeerlist:10.10.10.10 10.10.10.11 w32tm /config /syncfromflags:MANUAL
Then sync:
w32tm /resync or net stop w32time net start w32time
To check:
w32tm /dumpreg /subkey:parameters w32tm /monitor /computers:localhost w32tm /stripchart /computer:<hostname of domain controller> +offset means server is ahead of pc, - server is behind pc
