Problem with time sync
I got a problem with Windows 7 clients - cannot sync time with Linux NTP server. Windows XP clients sync with the same server without errors. My Windows 7 clients can get time from public NTP servers through Internet, but not from local servers in the same IP 4 subnet. From sles11sp2 C:\Windows\system32>w32tm /config /manualpeerlist:192.168.2.99,0x8 /syncfromflags:MANUAL /reliable:yes /update The command completed successfully. C:\Windows\system32>net stop w32time The Windows Time service is stopping. The Windows Time service was stopped successfully. C:\Windows\system32>net start w32time The Windows Time service is starting. The Windows Time service was started successfully. C:\Windows\system32>w32tm /resync /rediscover Sending resync command to local computer The computer did not resync because only stale time data was available. From sles10sp3: C:\Windows\system32>w32tm /config /manualpeerlist:192.168.2.100,0x8 /syncfromflags:MANUAL /reliable:yes /update The command completed successfully. C:\Windows\system32>net stop w32time The Windows Time service is stopping. The Windows Time service was stopped successfully. C:\Windows\system32>net start w32time The Windows Time service is starting. The Windows Time service was started successfully. C:\Windows\system32>w32tm /resync /rediscover Sending resync command to local computer The computer did not resync because no time data was available. From public server: C:\Windows\system32>w32tm /config /manualpeerlist:us.pool.ntp.org,0x8 /syncfromflags:MANUAL /reliable:yes /update The command completed successfully. C:\Windows\system32>net stop w32time The Windows Time service is stopping. The Windows Time service was stopped successfully. C:\Windows\system32>net start w32time The Windows Time service is starting. The Windows Time service was started successfully. C:\Windows\system32>w32tm /resync /rediscover Sending resync command to local computer The command completed successfully.

Hi, Based on my research, please follow the steps in Configure a manual time source for a selected client computer to perform the configuration. If issue persists, please use Network Monitor to troubleshoot the issue. More reference: Windows Time Service Tools and Settings How the Windows Time Service Works Error message when you run the "w32tm /resync" command to synchronize Windows Server 2003 or Windows SBS to an external time source: "The computer did not resync because no time data was available" The computer did not resync because no time data was available (w32tm) Hope this helps.

Hello, Thank you for a long list of useful links, I've studied all with the same result in w32tm /resync: The computer did not resync because... But this looks strange: C:\Windows\system32>w32tm /monitor /computers:localhost localhost[[::1]:123]: ICMP: 0ms delay NTP: +0.0000000s offset from local clock RefID: nsbes1.galend.local [192.168.2.100] Stratum: 2 Warning: Reverse name resolution is best effort. It may not be correct since RefID field in time packets differs across NTP implementations and may not be using IP addresses. Also after restarting w32time in System Log I have Time-Service event with Event Id 37: The time provider NtpClient is currently receiving valid time data from 192.168.2.100,0x8 (ntp.m|0x8|0.0.0.0:123->192.168.2.100:123).

Hello, Are the results and events gathered from the NTP server or the win7 client? On the client machine i am afraid that we cannot set it as a reliable time source.
