NTP on Cisco Switch & Windows 2008 R2

Railroad used Ask the Experts™
I have several Cisco 2960's I'm trying to setup NTP on.

I've configured my DC running Windows 2008 R2 to be an NTP client and server as described in this article: http://support.microsoft.com/kb/816042.

On the switch I've configured them with "ntp server" which is the IP address of the DC.  Show NTP Associates shows:

      address         ref clock     st  when  poll reach  delay  offset    disp
 ~    4   224  1024  377     1.3  172164  15875.
 * master (synced), # master (unsynced), + selected, - candidate, ~ configured

I believe this is showing it's configured, but is not synced.  I know the times are different, they are however within a few minutes of each other.

Oh... net time /DOMAIN:DOMAIN /SET from a workstation works fine for using the DC as an NTP server.

What's interesting is that it clearly knows who the server is- it has the reference clock address and the stratum. Have you checked lately to see if the status has changed any?


Looks like it just took some time for it to actually sync.
