qbdbmgrn Not Running on This Computer – Step-by-Step Fixes

Imagine this: You’re trying to open your QuickBooks company file over the network, and instead of diving into your numbers, you get the message:
“qbdbmgrn not running on this computer.”
Frustrating, right?

This error message usually appears when QuickBooks is unable to connect to the Database Server Manager, blocking access to your shared file. In this guide, we’ll break down what this error means, why it happens, and—most importantly—how you can fix it quickly.

Let’s get your accounting back on track.

The “qbdbmgrn not running on this computer” error stops multi-user access in QuickBooks. Here’s how to get your database server up and running.

What Is qbdbmgrn in QuickBooks?

The QuickBooks Database Server Manager (qbdbmgrn.exe) is a background process that enables multiple users to access the company file on a network. If this process fails, the software can't switch to multi-user mode or locate the file stored on a server.

When you see "qbdbmgrn not running on this computer", it means the database service isn’t active on the host machine. Without it, your file may be locked or appear offline to other users.

Why You See qbdbmgrn Not Running on This Computer

Here are the leading causes of this error:

1. Database Server Manager Isn’t Installed or Active

If QuickBooks isn’t installed correctly or the server manager wasn’t set up, the error will show up during file access.

2. The Service Has Stopped

The qbdbmgrn service may have been stopped after a system reboot, crash, or a conflict with background tasks.

3. Windows Firewall Is Blocking QuickBooks

Firewalls and antivirus software can interfere with essential services like qbdbmgrn.

4. Multi-User Hosting Is Not Enabled

If the server computer is not set up to host the company file, no other device will be able to access it.

5. Corrupted Network Files (.ND)

Damaged or missing .ND files can lead to improper linking between QuickBooks and the company file.

How to Identify the Error

Here’s how you know you’re facing this issue:

• The company file won’t open in multi-user mode.

• QuickBooks File Doctor flags the Database Server Manager.

• A scan reveals qbdbmgrn.exe is not running.

• Other users can’t access the company file.
