How to Fix: QBDBMgrN Not Running on This Computer
Let’s go through the top solutions to resolve this issue:
1. Restart the QuickBooks Database Server Manager
A simple restart often resolves the problem:
Press Windows + R, type services.msc, and hit Enter.
Find the service named QuickBooksDBXX (where XX is your version year).
Right-click on it and choose Restart.
Ensure the Startup Type is set to Automatic.
2. Add QBDBMgrN as a Firewall Exception
Sometimes, Windows Firewall blocks the service from running:
Open Control Panel > Windows Defender Firewall.
Select Allow an app or feature through Firewall.
Click Change settings and then Allow another app.
Browse and add QBDBMgrN.exe from QuickBooks install directory.
Check both Private and Public boxes and save changes.

Rename it to CompanyName.qbw.nd.old.
Open QuickBooks and try accessing the file again—it will regenerate the .ND file.
