Time is 3 mins ahead on computers but correct on domain controller

Question

I have a simple domain with 1 domain controller (Server 2012R2) that is also the PDC emulator. Lately, some domain joined computer's times have been fast by about 3 mins. When i check w32tm /query /source it says "local CMOS clock". Not matter what I do, it will not change.

On the DC, it also says "Local CMOS Clock", even though i have set it through w32tm to use the pool.ntp.org sites. I even setup a GPO and set the Configure Windows NTP Client to the pool.ntp.org servers, and enabled Windows NTP Client, and linked it to the Domain Controllers OU.

I do a gpupdate /force on the DC, and no change. I have stop/started w32tm, I have unregister/register w32tm, and nothing works on either the DC or the computers. The firewall is completely off on the domain controller.

Below is the out put for w32tm /query /configuration & w32tm /query /status for the Domain Controller:

Below are the same results from a domain joined computer:

Answer 1

I have unregister/register w32tm, and nothing works on either the DC or the computers.

Some settings are via group policy so the unregister/register is at least partially unsuccessful.

and nothing works on either the DC or the computers

I'd check the problem members all got the domain network firewall profile.

Answer 2

No change. PCs and DC still say Local CMOS Clock for w32tm source...
Might try using a different source.

w32tm /unregister
net stop w32time
w32tm /register
net start w32time
w32tm /config /manualpeerlist:<ntp ip address> /syncfromflags:manual /reliable:yes /update
net stop w32time
net start w32time

then check

w32tm /query /source
w32tm /query /configuration
