Password Change Notification Service received an RPC exception attempting to deliver a notification - after upgrading from Windows Server 2016 Essentials

Completed a Windows Server 2016 Essentials to Windows Server 2019 Essentials upgrade following the migration guide. After it's completed, I'm noticing a large number of errors, from PCNSSVC (Error 6025):

Password Change Notification Service received an RPC exception attempting to deliver a notification. 

The password change notification target could not be contacted.

User Action:
The target server may not be running. Verify that the target server is running.

It appears that this one account is attempting to use a password sync protocol on the old server (W2K16E). I'm getting thousands of these errors in the past 24 hours (it appears every minute). I tried deleting this account from AD and re-installing QuickBooks (which re-creates the account) - but after reinstalling it - the error comes back. I've tried googling this to no luck. Hoping you may have some suggestions on how to eliminate this error.

FYI - this server is configured to Office 365 through Azure AD Connect - but I'm not seeing any sync errors there.

    It's not called that or I would have already uninstalled it. I tried Features and Roles - nothing. I finally found it, it was called FOREFRONT PASSWORD CHANGE NOTIFICATION SERVICE". What's strange, is I uninstalled that from the Windows Server 2016 Essentials... how did it get re-installed on 2019 Essential... is that something that comes default in 2019? Strange, I uninstalled it, and hopefully it'll stay gone (as I don't see any policies that would install it). Thanks

    Have a look for 'WSE Group Policy Password Synchronization', it runs on any server that is a Domain Controller and starts a script called pcns.ps1.
