The time provider NtpClient cannot reach or is currently receiving invalid time data from 184.108.40.206 (ntp.m|0x0|192.168.0.10:12
The time provider NtpClient is configured to acquire time from one or more time sources, however none of the sources are currently accessible. No attempt to contact a source will be made for 15 minutes. NtpClient has no source of accurate time.
Time Provider NtpClient: No valid response has been received from manually configured peer 220.127.116.11 after 8 attempts to contact it. This peer will be discarded as a time source and NtpClient will attempt to discover a new peer with this DNS name.
Followed steps of MS KB816042 to set up an authoritative time server in Windows 2003 to no avail.
Also tried solution from http://www.jsifaq.com/SF/Tips/Tip.aspx?id=8497
to no avail.
At this point, I've tried monkeying with both the PDC and SDC (both are experiencing this error) and client PC's are experiencing:
The time service has not been able to synchronize the system time for 49152 seconds because none of the time providers has been able to provide a usable time stamp. The system clock is unsynchronized.
How do I get the PDC established as the authoritative time server, conferring with an internet time source (such as time.nist.gov or similar) and get all the other PC's (SDC and all clients) syncing with the PDC?
BTW, UDP port 123 is open.
