Hi All What is the easiest way to config my 2008 DC to sync its time from an external source? (thus allowing clients to sync against the DC) I have looked around the web and found many articles that use different methods that either don't work or require so damn much manual work what's the point of using a computer to do it!!! thanks for saving my sanity... Ross

Hello Ross,I assume the actual synchronize function offered by Windows (click on the clock in the task bar > change date and time settings > Internet Time) does not satisfy you because the update interval (1 week) is rather high ?If so, you could write a batch script which starts (with admin rights) every x mins with:net time /setsntp:time.windows.comw32tm /resyncSincerely,Erkan YILMAZ(assuming DC stands for Datacenter)

Thanks Erkan DC actually stands for domain controller but it still works fine of course. There needs to be a better way to do this...hopefully MS comes up withmore friendly solution in the future. thanks again. Ross

Indeed. There could be made a new feature to configure the update interval easily in the "Internet Time" dialog Or - if possible - you could try to change the value in the registry for HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\UpdateIntervalErkan

On 2003 Domain Controllers(PDC only) have I always with success used this command: w32tm /config /manualpeerlist:IPorDNS-NAME /syncfromflags:manual /reliable:yes /update where "IPorDNS-NAME" is the IP address or DNS Name for the reliable time source. If you wish to setup more than one reliable time source, you have to surround the option with doublequotes (") and with a space between: w32tm /config /manualpeerlist:IP1 IP2 /syncfromflags:manual /reliable:yes /update It seems like the same command can be used on 2008 DC's. Hope this help, Best regards, Bjarne Duelund

On my Windows 2008 server, which is the Primary DC, the tab Internet Time is missing.In order to sync the clock, I had to w32tm /config /manualpeerlist:194.30.169.189 /syncfromflags:manual /reliable:yes /updatew32tm /resyncThese two commands returned without error. Then all the clients in the domain resynced withinan hour or so.Feel free to use my time server above.Harold Naparst
