Hi All!
We have 2 DC's, the first is a PDC and it is configured to receive time from an external time server. The second DC receives time from the first DC and other workstations receive time from one of DC's. Everything worked fine until last week.
The problem is that, however the confoguration of the first DC is OK, its ignored the configured time source and get time from the LOCAL CMOS. Let's see:
C:\Users\Administrator.DOMAIN>w32tm /query /configuration

Now I configure again:

The command completed successfully.

(Local CMOS Clock - it is a difference! Earlier, when the state was pending, the source was: Free-running System Clock) Why?
Some week ago, the output of w32tm /monitor command was:
C:\Users\Administrator.DOMAIN>w32tm /monitor
DC1.domain * PDC *[[fe80::8049:7f2a:d367:cf41%8]:123]:

ICMP: 0ms delay
NTP: +0.0004628s offset from DC1.domain

Stratum: 3
I registered the time services again and restart the server las week, but nothing changed.
I don't know whats wrong :( Please help me.
Thanks in advance!
