I detected that when I stop NETLOGON Services, server 2019 doesn't restart unexpectedly. But when start NETLOGON Services, it still restart every 5 ~ 10 minutes.

What's the history here? New domain controller or new problem? How many domain controllers?



@Dave Patrick 

I have plan upgrade AD from 2008 to 2019. On root site have 02 DC2019 (Also have issue "restart unexpected" then fixed by re-creating health mailbox account) but Child domain is not resolved. In this site, I forcing install DC2012 to client connect normally and with DC2016 & DC2019, if start NETLOGON services. they are rebooted unexpected. 

I doubt that some suspicious client attacking thought NETLOGON services. :( 

Please save me. This issue still not resolve for 3 months

I can still only understand about a third of this. Upgrading domain controllers in this broken environment is never recommended. You may want to restore a recent known good backup and work from there.
