NTP help

[Guest 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
