There are many things that could affect the timy syncronisation:
- Wrong ACLs (restricts) in your ntp.conf
- GPOs telling the clients to get the time from a different source, than
the one with the PDC role (default).
- 'Windows Time' Service disabled
- etc.


Can you:
- check the above
- post your ntp.conf
- have a look at the 'w32tm' command
(http://technet.microsoft.com/en-us/library/bb491016.aspx) and see which
source it is querying, when it had last time synced, etc.
