Guest Domon Posted October 23, 2008 Posted October 23, 2008 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 -- Domon ------------------------------------------------------------------------ Domon's Profile: http://forums.techarena.in/members/domon.htm View this thread: http://forums.techarena.in/windows-server-help/1059787.htm http://forums.techarena.in
Guest Meinolf Weber Posted October 23, 2008 Posted October 23, 2008 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?

Guest Domon Posted October 24, 2008 Posted October 24, 2008 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 -- Domon ------------------------------------------------------------------------ Domon's Profile: http://forums.techarena.in/members/domon.htm View this thread: http://forums.techarena.in/windows-server-help/1059787.htm http://forums.techarena.in
Guest Meinolf Weber Posted October 24, 2008 Posted October 24, 2008 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: http://support.microsoft.com/kb/816042 What kind of hardware NTP is it?

Guest Domon Posted October 25, 2008 Posted October 25, 2008 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?
