Domain Controller Time Sync Issue

hello,

we have domain controller vm on 1 of our servers. re had issue group policy have cleaned up. have checked rsop.msc see if gpo's being applied dc , there none.

the dc looking @ local cmos time , off 1 minute , 50 seconds. have done following:

reg add hklm\system\currentcontrolset\services\w32time\timeproviders\vmictimeprovider /v enabled /t reg_dword /d 0

1.net stop w32time

2.w32tm /unregister

3.w32tm /register

4.net start w32time

5.w32tm /config /update /manualpeerlist:"0.pool.ntp.org,0x8 1.pool.ntp.org,0x8 2.pool.ntp.org,0x8 3.pool.ntp.org,0x8" /syncfromflags:manual

6.w32tm /config /update

7.net stop w32time && net start w32time

8.w32tm /resync /rediscover

now time sync , goes correct time, after few seconds reverts host time. there missing? should on host machine?

ok,

so went onto host server , changed time 0.pool.ntp.org,0x8 went onto dc , did same thing. on every physical server did a: net time \\<server-fqdn> /set /y

using time.is see if accurate , results:

clock 0.7 seconds behind.

accuracy of synchronization ±0.025 seconds.
