If you're using WPKG Client, it's a good idea to put just net time \\timeserver /set /yes in a "pre" script.
This command succeeds and works even if your date is off by a lot(unlike normal NTP).
Net Time Plus NTP
This package performs a net time sync plus it also sets your domain NTP server as the primary NTP source and configures ntp.org pool servers as fallback NTP sources. The latter is worthwhile for laptop users who aren't necessarily logged on to your domain.
The hex flag 0x8 after the primary NTP server means use standard NTP client behaviour, the hex flag 0x2 designates the NTP server as a fallback to be used if the primary is not available.
