Domain controllers have different times

Hello,

For the one that is off by 4 minutes, can you check it's time in the BIOS?  Sometimes the BIOS and Windows try to override each other on time settings.

Unfortunately I'm not at the location today.

How are you checking the time setting for each DC?  I have found the registry keys to be unreliable - On one of my local DCs, the value from HKLM/System/CurrentControlSet/Services/W32Time/Parameters/NtpServer shows - time.windows.com,0x9 - as the time source.  But from a command prompt on a DC, I use:  w32tm /monitor (This will show me the time source and current off-set for each DC in the domain).  I get the time source of this DC to be the PDC Emulator for the domain, which then gets its time from the PDC Emulator in the forest root.

Attached is what I got after running w32tm/ monitor.  If I reading it correctly, the PDC is getting it's time from my other DC spcala185.  Is that correct?

Please read over this to understand how time works in a AD environment.

If you are having issues with a DC that doesn't hold PDC emulator role then http://technet.microsoft.com/en-us/library/cc758905(v=ws.10).aspx

I ran the command but there was one error.  See attached
