Time Synchronisation without Internet Access or 3rd party time server

Hi all,

I've just built a standalone network comprised of the following:

Domain Controller
- Windows Server 2003 (2003 forest functional level)
- Exchange Server 2003 (native mode)
- all FSMO roles

Member Server (NOT DC)
- Windows Server 2003
- Sharepoint Portal Server 2003
- Project Server 2003
- SQL Server 2000

Clients
- Windows XP
- Office 2003

Everything seems to be happy, except the time synchronisation. There is
absolutely no Internet connectivity allowed into this network, and the
cabling etc precludes us from accessing the Internet anyway. Additionally,
they don't want to add a third party NTP server into the mix; they want a
pure MS environment except for AV and backups.

So, what I've done is this:

- configured the AnnounceFlags registry key on the DC as per KB 816042.
Then installed hotfix 830092.
- the clients haven't been configured, so by default they're using the
domain hierarchy and speaking to the PDC Emulator, which is of course the
only DC.
- the member server was configured using the following setting, which I did
on the advice of MS PSS:
1. w32tm /config /manualpeerlist:<ip address of DC>,0x8
/syncfromflags:MANUAL
2. net stop w32time & net start w32time
3. w32tm /resync

So, the DC has had a registry tweak, the member server has had a w32tm
tweak, and the workstations haven't been touched. Three different
configurations, and none of the machines are happy.

On the DC I was receiving this error:
Event ID 36:
"The time service has not been able to synchronize the system time for 86400
seconds because none of the time providers has been able to provide a usable
time stamp. The system clock is unsynchronized and cannot provide the time
to other clients or update the system clock."

On the member server I was receiving this error:
Event ID 50:
"The time service detected a time difference of greater than 5000
milliseconds for 900 seconds. The time difference might be caused by
synchronization with low-accuracy time sources or by suboptimal network
conditions. The time service is no longer synchronized and cannot provide
the time to other clients or update the system clock. When a valid time
stamp is received from a time service provider, the time service will
correct itself."

On the workstations I was receiving this error:
Event ID 36:
"The time service has not been able to synchronize the system time for 49152
seconds because none of the time providers has been able to provide a usable
time stamp. The system clock is unsynchronized."

PSS then recommended that I configure each machine (including the PDC
Emulator) with run net time/setsntp:<name of PDC Emulator> and then restart
the w32time service. I did this, but as per KB 816042, this results in
errors 38, 47 and 29 on the PDC, which basically state that the PDC is
receiving invalid time data, that no valid response has been received after
8 attempts and that none of the valid sources are currently available.

So, it appears that none of the machines are happy with the current time
synchronisation configuration. Has anyone else managed to get time
synchronisation working happily in an environment with no Internet
connectivity and with no dedicated third party time server?? As I
mentioned, I've logged a call with PSS but they're receiving errors 36 as
well, so it seems that the solution given in KB 816042 isn't really a
workable solution at all.

Any ideas??
Katherine Coombs
