If you're seeing the “QBCFMonitorService Not Running” blunders on Windows eleven, you are now not alone. This trouble regularly arises due to mistaken set up or previous versions of QuickBooks Database Server Manager. To remedy it, make sure QuickBooks and all services are up to date. Then, open Services.Msc, locate QBCFMonitorService, and restart it. If it’s not starting, run QuickBooks as Administrator or repair the installation. Firewalls and antivirus software can also block the provider, so make sure QuickBooks has exceptions. If issues persist, reinstalling the Database Server Manager may additionally assist.
