NTP help

[Domon]

Hi

My domain controller which is the PDC has encountered some warning and
errors during NTP time synchronization.

The errors are logged in this order.

1) Event 38 Source w32Time ( logged for a few times)

2) Event 47 source w32Time

Time Provider NtpClient: No valid response has been received from
manually configured peer <IP address> 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.

3) Event 29 source w32Time

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.

Does anyone know whta is likely the cause for this?

Thanks

Regards

Re: NTP help

Hello Domon,

This occurs when the PDCEmulator can not contect the configured time source
to update the time. Do you use an external time source or how did you configure
the PDCEmulator?

Re: NTP help


Hi

Currently, I have a hardware NTP server in Subnet A. My PDC is located
in Subnet B. I have a win 2003 server acting as a time source master
node for Subnet B. Thus my setup is as below.

1) Time source master node will sync it's time with the hardware NTP
server.
2) My PDC will then sync it's time with the time source master node.

I configured my PDC to sync to the time source master node by using the
following command.

w32tm /config /manualpeerlist:<peers> /syncfromflags:manual
/reliable:yes /update

Are there anything that I have not done or configued wrongly?

regards

Re: NTP help

Hello Domon,

The PDCEmulator can only sync with a NON-DOMAIN member, so an external time
source or hardware clock is needed.

See here:

What kind of hardware NTP is it?

Best regards

Re: NTP help


Hi

Thanks for the prompt reply.

The 2003 server that my PDC is synchronizing with is not a member
server of the domain. It is a standalone server. My hardware NTP is a
network time server from Symmetricom. Or could be be the NTP setting in
the standalone server is not configured properly? I have gone through
the article provided in your reply. Is the configuration in it
applicable to both standalone and PDC?

Regards
