How to change Date and Time of windows Server 2012 R2(mssql 2014) joined to a Domain(windows server 2012). If I change Time and Date of Windows server 2012 R2(Non-DC) different from DC will that able to work authenticating users on Domain Controller. FYI DC and Non-DC are on same network.

Is it possible that authentication should work even after DC and Non-DC having different time stamps. Pls help me with this I really appreciate the help

  • AD relies quite heavily on time. Don't manually set times on devices in the AD schema, I don't even know what purpose this could serve... – Lenniey Mar 1 '18 at 8:25

No. Don't change the date/time on a domain joined Windows machine. Authentication will break. You can change the time zone but not the actual time or date.

Kerberos defaults in Active Directory require the time difference to be less than 5 minutes. But regardless of the allowable time difference, still don't change the date/time on a member. Just don't.

  • Thank you Ryan, If I change time zone to back date do you think authentication works? – Shekar Mar 1 '18 at 17:25
  • I have a requirement to back date. Is it possible by any chance and authentication should work fine – Shekar Mar 1 '18 at 17:35
  • For the duration that the server has a time set greater than 5 minutes from the domain controller, authentication will be broken. As soon as the time returns to within 5 minutes from the DC, authentication will work again. Important Caveat: If the date is wrong for too long, the system will likely lose its trust relationship with the domain and won't be fixed after setting the date back. – Ryan Bolger Mar 2 '18 at 0:01
  • Thank you for your answer. I wanted to know is there any tool that fool the Domain controller, or is there any other ways going to back in date still authentication should work – Shekar Mar 2 '18 at 2:47
  • No. Perhaps if you described the reason you want to change the time on a domain member, we could suggest an alternative that doesn't require changing the time. – Ryan Bolger Mar 2 '18 at 6:09
