I just recently setup a new dc with all the fsmo roles. I am trying to setup the time server to sync with an external time source. So I found the microsoft support artical on how to configure an authoritavtive time server in windows server 2003. The time server I used to sync with is time.microsoft.com, but after making the change and waiting a day our domain time is 5 minutes off the correct time.
Does anyone have any idea why it would be off 5 minutes? Is there a better time server I should be using?
