Windows 2003 Time Provider

Posted on 2005-05-02

I have a single Windows 2003 domain controller in our environment that acts as a NTP Time Server. I have tried to configure it with various time servers from the internet (Naval Observatory) that I had read from certain websties, but I continually get the event ID 29, which states that the time source is not currently accessible. I was getting this when I had as the time source, but I am also getting it from the other sources also. I even changed the method in which the server polls the time servers in case they are not running the Windows operating system. Which time source should I use so I don't get that message?

    Do you have a firewall between your server and internet. In that case you have to open the port used for the ntp protocol

    Yes we do have a firewall, that could be causing the problem. I hadn't even thought of that..I will try that and let you know. Thanks.

    If you are behind a firewall, you may be blocked from accessing NTP services on the Internet. Use “net time /querysntp” and “net time /set” to test NTP access.
