I manually set server 2012 to synchronize to an external NTP server per microsoft's instructions, and to sync every 900 secs (15 minutes)
After a restart, running w32tm /query /source returns "local cmos clock"
w32tm /query /peers shows the 4 ntp servers I configured as pending, with a countdown from 900 seconds.
After 900 seconds, finally the peers are accepted as a time source. Why doesn't this happen during startup?
w32tm /monitor is able to get valid time
