I think you will have trouble doing this. AD's time service is not a true NTP service - it's SNTP with a dash of smarts around increasing frequency and backing off, plus automatic selection of masters / distribution hierarchy. I'd suggest setting up the NTP server to use the NTP Pool project (pool.ntp.org, or the appropriate country subdomain) and configuring AD to synchronise to the NTP server (that should work fine).
