I have cisco 1841 in lan that is a gateway for the Lan.In that Lan i have domain controler with NTP enabled. After I configure ntp server (ip of domain controler) i get the message that ntp is "insane"
Here is the output fro sh ntp status and sh ntp assotiation detail
sh ntp status

I have never seen this work, nor been able to get it to work using the W32Time service on Windows 2000 or 2003. 3rd party 'proper' NTP time servers work if you disable the W32Time Service.
The best way to configure this is to swap it around - i.e. get a couple of your core switches/routers to sync externally to valid time servers or better still an internal GPS clock. Then synchronise your Windows Domain Controller off the Cisco switches/routers.
Like Andy, I've also experienced a lot of issues getting Cisco equipment to time sync with Win 2000 or 2003. In theory 2003 is using NTP and we would expect MS to follow industry standards, most Cisco equipment using SNTP will sync ok, but there is still those few devices that don't.
If you don't want to sync off your Cisco devices, then I would suggest setting up a small linux distro and setting it up as your domain time source.
