Hi: I am having troubles with w32tm service in the domain controller that acts as the PDC role, I followed the steps to configure the DC to sync with external source like is indicated in the http://support.microsoft.com/kb/816042 article. But after that, and restart the service several times is not working. When I ran the command "w32tm /query /status" I receive: C:\Users\root>w32tm /query /status Leap Indicator: 0(no warning) Stratum: 1 (primary reference - syncd by radio clock) Precision: -6 (15.625ms per tick) Root Delay: 0.0000000s Root Dispersion: 10.0000000s ReferenceId: 0x4C4F434C (source name: "LOCL") Last Successful Sync Time: 23/06/2010 04:11:43 p.m. Source: Local CMOS Clock Poll Interval: 6 (64s)

Hi, Are you getting any NTP errors in the event log? Also, can you verify which registry keys you changed here in the forum? -- Mike Burr

Hi Carlos , these might be useful for Windows 2008 Step 1: Net time /setsntp: W32tm /config /syncfromflags:manual /manualpeerlist: W32tm /config /reliable:yes W32tm /config /update W32tm /resync Pause Exit Step 2: [HKEY_LOCAL_MACHINE\SYSTEM \CurrentControlSet\Services\W32Time\Config] "AnnounceFlags"=dword:00000005 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters] "Type"="NTP" [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer] "Enabled"=dword:00000001 Step 3: Net stop w32time Net start w32time Net time Pause Exit Command in login script: Net Time \\<LocalTimeServer'sName /Set /Yes Regards.

Hi CarlosH. , Thanks for posting here. After reading your post I understand you though PDC may not sync time with external time source after you set the external time source on PDC with following KB 816042. After you configured registry settings, please check the objects below : 1. Ports are not blocked. 2. No third-party services are causing the issue. 3. Make sure all the domain controllers are under default domain controller`s OU. Finally , please perform “w32tm /resync ” to determine if settings effected. According what you provided right now ,it’s hard to isolated this issue ,please post how you set external server on PDC here , and any related event log will very helpful . Here is an article which about how to debug time service issue How to turn on debug logging in the Windows Time Service http://support.microsoft.com/kb/816043/ Tip: if you set multi time servers, please add comma between each server. Example: time-a.nist.gov,0x8,time-b.nist.gove,0x8,time.nist.gov,0x8,time-nw.nist.gov,0x8 Thanks. Tiger Li PS: On July 1st we will be making Windows Server 2008 R2 General forum read only.
