I have a Cisco 2821 10.1.1.1 as a VGW and router in the network sitting behind a Cisco ASA5505(10.1.1.2)
Was running 12.4-3g prior to upgrading.
The ASA , switches, another router/vgw at anthoer site, Cisco WLC and Cisco UCM server and customer Domain controller are all set to get their NTP from the this VGW.
10.1.1.1 is acting as the NTP server for the network. and when you do a show ntp status it shows syncd.

The ASA, WLC and other router seem to be synching to this gateway.
In the WLC it says synced with time server
the other router says sync stratum 3
In the UCM server is says ntp rechable but customer is reporting time is off on the phones.
Also customers DC is getting this error when trying to sync
((computer didnt resynch because no time data was available.))
when doing a debug on NTP i get this
""windows server""

net0/0.10' (x.x.x.x).

When you point the customers DC to a public time server it stays sync'd with no issues and same thing with the UCM server.
Any thoughts would be greatly appreciated.
