Weird ntp issue

ok, have a weird one.
have set the GPO to look at our time server, all servers are supposed to
look at ntp.us.edu
But I started getting lots of these id:50 errors on all our servers (below).
Turns out they are all looking at time.windows.com, the default!
So I checked with rsop.msc and gpresult, and the servers ARE getting and
applying the GPO.
Looking online, everything I see says that the registry needs to be modified
at HKLM\services\w32time. But my adm file is modifying
HKLM\software\Policies\W32time.

So I thought my adm file was corrupted and wrong, but when I loaded a bran
new test domain and looked at the adm files, they also look at
HKLM\software\Policies\W32time.

I am so confused, and google is not helping, can anyone help me out?

Event Type: Warning
Event Source: W32Time
Event Category: None
Event ID: 50

User: N/A

Description:
The time service detected a time difference of greater than 128 milliseconds
for 90 seconds. The time difference might be caused by synchronization with
low-accuracy time sources or by suboptimal network conditions. The time
service is no longer synchronized and cannot provide the time to other
clients or update the system clock. When a valid time stamp is received from
a time service provider, the time service will correct itself.

Hello blankmonkey,

In a domain make your life easy and let the default time settings. The DC
with the PDCEmulator role is the time source in a domain, all DC's sync with
that and all member servers and workstations sync with one available DC.
The PDCEmulator configure to an external time source and and you are done.

So in your case let the PDCEmulator sync with ntp.us.edu, before that revert
the GPO setting and then set it to not configured:
w32tm /config /manualpeerlist:ntp.us.edu /syncfromflags:manual /reliable:yes
/update

On the clients run:
w32tm /config /syncfromflags:domhier /update

After that run:
net stop w32time
net start w32time

Best regards
