As far as I know, this has been broken for most of the last 6 months.
Messages from the newsgroup are gatewayed to questions, but questions
traffic never makes it to the newsgroup.

My understanding is domain members' w32time service will synchronize
(using MS-SNTP A.K.A. [MSNTP] authenticated by a machine account
secret) to the domain controller holding the PDC emulator "flexible
single master operation" or FSMO role.  So if you have any domain
members using w32time, you'll want to have at least one DC (the PDC
FSMO role holder) running w32time (A.K.A. Windows Time Service).

I run ntpd on all my domain's DCs except for the PDC emulator, and
have the PDC emulator's w32time sync to one of the DCs running ntpd.
