This action requires Windows administrator permissions - Quickbooks Enterprise issue

Running Quickbooks Enterprise on Microsoft Remote Desktop server (2018), users get "This action requires Windows administrator permission" prompt from times to times. A reboot of RDP server will fix the issue temporarily but not good enough.

There's already a lot of information on Internet suggesting to turn off UAC and change the Quickbooks database services logon to local system account. For example, I'm running Quickbook Enterprise 18 and I would change the login account to "Local System account" in "QuickBooksDB28" service.

However, that was not enough to fix this issue. I went to User Account in Control Panel, then changed the user, "QBDataServiceUser28" from User group to Administrators, and restarted the service. That seemed to fix the issue.
