NTP Server Providers
I just finished adding a new Windows 2012 Server as a new DC as a VM. I have another Windows 2012 Server DC as a physical server, and finally one Windows 2003 Server R2. I transferred all (5) FSMO roles from the 2003 DC to the Windows 2012 Server that is on the physical without issue, and all appears to be working well.
Server Manager on the Windows 2012 Server that holds all the FSMO indicates a problem with BPA results: Error The PDF Emulator master "servername" in this forest should be configured to correctly synchronize time from a valid time source.
I ran the following command on the pdc emulator:
w32tm /config /computer:"servername" /manualpeerlist:time.windo
On the other two DCs I ran w32tm /config /syncfromflags:domhier /update
My first question is whether time.windows.com is the best NTP selection period? We are on the east coast if that matters. I thought I remember there was a problem using this NTP server in the past. I am not entirely sure that was the case, so that is why I ask.
The second question is if the above commands are all that's needed to configure our PDC Emulator to sync time with a credible external time source, and have all other servers and client workstations sync time with the PDF Emulator.

frankhelk confirmed using pool.ntp.org is the best NTP source, but his article lacked detailed instructions on how to do this on a Windows Server. I found an article that gave me this precise information. I appreciate the help!!!
no problem - I know that my answer is a bit abroad of the AD topic - I'm happy that your problem is solved anyhow. Nevertheless I prefer the classic NTP client, and I still recommend it.
May you have always good times :-)
