What ‘QBDBMgrN not running on this computer’ Error Message Means ?

To better understand why QBDBMgrN not running, we will first explain to you what exactly the QBDBMgrN (QuickBooks Database Server Manger Service) is, and why the QuickBooks software needs it to run properly. QBDBMgrN is an executable process on Windows with a so-called ‘.exe’ extension, which you can see in the task manager of your computer.

Simplified, the QB data base server manager was developed by Intuit to enable more than one user to access the company file and database on the hosting server where the company file is stored.
