I can't seem to get our 2008 PDC to sync with an external NTP server. I go through the w32tm /config /manualpeerslist:PEERS /syncfromflags:manual /reliable:yes /update and it completes successfully. I try a w32tm /resync and it comes back that "the computer did not resync because there is no time data was available". I have tried different forums and solutions from them and have yet to succeed.Ryan Blackerby

Hello, please post the output from w32tm /monitor. Which event viewer errors do you have. Please run "net stop w32time" and "net start w32time" from an elevated command prompt and post the event viewer entries for the time service, give some minutes to complete.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hi, First, please check the “Configuring the Windows Time service to use an external time source” section in the following support article. Please make sure you have done all the steps as suggested, you can also use the Fix it tool instead. How to configure an authoritative time server in Windows Server http://support.microsoft.com/kb/816042 If the issue persists, please confirm that the 2008 DC can correctly resolve the name of the time source peer. Refer to: Run Command Prompt in Elevated window, run the command "nslookup PEERS" What is the result? If any trouble is encountered, please let us know. For further troubleshooting, please help gather the following files on the 2008 DC.

Hi Ryan, According to the above error, your issue is caused due to the DNS factor. For more information on the error “NtpClient was unable to set a manual peer to use as a time source because of DNS resolution error on…”, you can refer to the following support article: Event ID 134: http://technet.microsoft.com/en-us/library/cc756393(WS.10).aspx Please help clarify how you configured DNS on the 2008 DC. Which 'PEERS' are you using? After verifying the DNS settings, please run "nslookup PEERS" to make sure the 2008 DC can correctly resolve the name of the time source peer. If the issue persists, please help gather the following files on the 2008 DC. netdiag /v >c:\netdiag.txt ipconfig /all > c:\ipconfig.txt dcdiag /v /c /d /e /s:dcname >c:\dcdiag.txt w32tm /monitor >c:\monitor.txt w32tm /query /peers /verbose >c:\peers.txt Thanks.

Ok i have the issue fixed now. Seems there was a border router setting that did not allow the info traffic into our network (actually blocked by the company our domain goes through to hit the outside world). Now symcing is great. Thanks for the help and advise.Ryan Blackerby
