After applying Microsoft Fix it 50395 from KB816042 and specifying ntp time servers ",0x8,0x8" the registry "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time\Parameters\NtpServer" value still lists ",0x1".

A Firewall rule that allows outbound UDP traffic to all remote machines on port 123 for all applications has been manually created. The NetTime application is able to sync the time using sucessfully. So I don't expect a TCP/IP connectivity, Name Resolution service, network that is experiencing high volume delays or inaccurate time source to be a problem.

This Windows Small Business Server 2011 (Window Server 2008 R2) was upgraded from a SBS 2003 machine. This PDC doesn't seem to sync its Windows Time service using an external internet time source, because:

  1. The event log displays event ID 12 when stopping and starting W32Time.
  2. w32tm /query /status shows "Source: Local CMOS Clock"
  3. w32tm /monitor shows for this server the time difference with itself and RefID: 'LOCL' [0x4C434F4C].
  4. w32tm /resync returns "The computer did not resync because no time data was available"

How to verify Windows Time service on this SBS 2011 PDC is actually syncing its time using the desired and/or server?
