We have two W2K3 Forest root PDC emulator servers that are set to be the time servers for our company. One is our main W2K3 AD server for our internal network our other is on our DMZ which hosts our web site servers. Both systems are configured to be the primary time server NTP hosts. However both systems receive the following event errors so neither is able to sync with external NTP sources.
Event ID: 29
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 60 minutes.
NtpClient has no source of accurate time.
Event ID: 47
Time Provider NtpClient: No valid response has been
received from manually configured peer time.windows.com
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.
Event ID: 38
The time provider NtpClient cannot reach or is currently
receiving invalid time data from
We have put on a packet tracer and see that it is able to reach the destination NTP server but it does not receive a reply packet. We installed a freeware NTP utility called about time and put it on both systems and it successfully reached and synced the time fine but it we would like to be able to utilize the built in time service. I have seen multiple questions on different NG's on this issue but none seem to answer our problem. Please Help!
