I'm building a small workgroup that must have time synchronization in a classified government LAN with no WAN connectivity. All the systems are running Windows 7 Enterprise. While it is obvious how to configure the clients to point at one system as the time server, I can find no guidance on how to properly configure the system which will host the authoritative time. I have attempted to configure the system with authoritative time to use an internal hardware clock, as described for a PDC master in KB article 816042, by setting the AnnounceFlags to 0xA. The client systems are able to compare their time with the master system using the w32tm /stripchart command, but a w32tm /resync commands results in the message "The computer did not resync because no time data was available."
(FYI, I am posting to this forum because of guidance provided by Kurt Hudson in the Windows Time Service thread at http://technet.microsoft.com/en-us/library/cc773013(WS.10).aspx.)
