What are the reasons due to which QBDBMgrN has stopped working?

The followings can be the reasons due to which QBDBMgrN has stopped working on the server:

• Some of the internal QuickBooks services, like QuickBooksDBXX or QBCFMonitorService, are not working on the server computer.

Now, it is time to look at the troubleshooting solutions for the reasons we have just mentioned above.

How to fix the following error message: QBDBMgrN not running on this computer?

Solution 1) Restart the necessary QuickBooks services on the server computer

1. On the server computer, open the Windows Start menu.
2. Into the search column, enter “services.mc” and select Services from the top of the list.
3. From the list of services, double-select QuickBooksDBXX (XX denotes the version year of QuickBooks Desktop).
4. From the Startup type: drop-down menu, select the Automatic option.
5. Look at Service status: and make sure it is either Started or Running. In case it is neither of them, choose the Start button.
6. Go to the Recover tab.
7. From the drop-down menus of First failure, Second failures, and Subsequent failures, select the Restart the Service option.
8. Click on the Apply button and then the OK button to save the changes you just made.
9. Repeat the above-mentioned steps in the same manner for QBCFMonitorService.

Solution 2) Manually set up firewall exceptions for QuickBooks programs

By configuring Windows Firewall settings, we can ensure that the QuickBooks programs don’t face any issues from the firewall side while connecting to the internet.

1. On the server computer, select the Windows Start menu.
2. Into the search column, enter “firewall” and select Windows Firewall from the list of search results.
3. Select the Advanced Settings option at the left panel.
4. Look for the Inbound Rules link, right-click it, and choose the New Rule option.
5. Select the Program option and then choose the Next button.
6. Select the This Program Path option and then choose the Browse button.
7. On the keyboard, press Windows + R keys altogether to open the Run window.
8. In the Run window, enter “C:\Program Files\Intuit\QUICKBOOKS YEAR” and then press the Enter key.
9. In the folder, look for the file named QBDBMgrN.exe and select it.
10. Select the Allow the Connection option and then choose the Next button.
11. Make sure to checkmark all the profiles as prompted and then choose the Next button.
12. Make a new rule and name it “QBFirewallException(name.exe).”

Now, create the outbound rules for the QBDBMgrN.exe file by repeating the steps mentioned above in the same manner, except you need to right-click on Outbound Rules instead of Inbound Rules.
