Am trying to sync the time of my cisco devices to the time of my domain. I am running a windows server 2008 domain but I am not using an external time source. I have tried to point my cisco device to my domain controller as the NTP server but without success.
Is it possible to use a windows server as an NTP server for my cisco devices?
Your post suggests that Screech may need to use commands for ntp source and ntp key. These commands are options which an installation may use if they choose, but should not be necessary just to get a router or switch to learn NTP from an NTP server.
The fundamental issue in your case is that the time protocol that runs for the Windows Domain is not NTP but is a simplified implementation of the time protocol. So you will not get the router or switch to learn time from the Domain using NTP. You might check and see if your routers and switches support SNTP and if they do you might try configuring SNTP pointing to the Domain.
