QuickBooks Database Server Manager (QBDSM) is essential for enabling multi-user access in QuickBooks Desktop. If it stops working, your team may be unable to access company files, switch to multi-user mode, or maintain reliable connections. Whether the service isn’t starting, your company file isn’t showing up, or you’re facing connection errors — don’t worry. This guide provides clear, step-by-step solutions to get you back on track.

What Does QuickBooks Database Server Manager Do?

QuickBooks Database Server Manager helps you:

• Share company files in a multi-user environment.

• Create and manage .ND (network data) files.

• Monitor and configure folders for shared access.

• Ensure smooth communication between server and clients.

Common Symptoms When QBDSM Isn't Working

• QuickBooks can’t open the company file in multi-user mode.

• “QuickBooksDBXX service not running” message appears.

• Company file isn’t listed in the server manager.

• H-series errors like H202 or H505 pop up.

• File access is slow or disconnected randomly.

Step-by-Step: Fix QuickBooks Database Server Manager Issues

1. Restart the QuickBooksDBXX Service

1. Press Windows + R, type services.msc, and hit Enter.

2. Look for QuickBooksDBXX (XX = your QuickBooks version, e.g., DB33 for 2023).

3. Right-click it and choose Restart.

4. If it’s not running, right-click Start.

5. Set Startup Type to Automatic.

Tip: Ensure you're logged in as an administrator to make these changes.

2. Rescan Your Company File Folder

1. Open QuickBooks Database Server Manager.

2. Go to the Scan Folders tab.

3. Click Add Folder and browse to the location of your QuickBooks company file.

4. Click Scan. Wait for it to detect and list your file.

Note: This generates the .ND file needed for network access.

3. Configure Windows Firewall and Security Software

If your firewall blocks QuickBooks ports, multi-user access may fail.

1. Open your firewall settings.

2. Allow the following ports for your QuickBooks version:

   • 2024: TCP 8019, 56728–56730

   • 2023: TCP 8019, 56727–56729

3. Add these QuickBooks programs as exceptions:

   • QBDBMgrN.exe

   • QBCFMonitorService.exe

   • QuickBooksServerUtilityMgr.exe

4. Use QuickBooks Tool Hub

QuickBooks Tool Hub is a free repair suite from Intuit.

1. Download QuickBooks Tool Hub

2. Open the tool and go to Network Issues.

3. Run QuickBooks Database Server Manager or File Doctor to fix network and permission issues.

5. Check Hosting Settings

Incorrect hosting setup can cause the Database Server Manager to malfunction.

• On the server, go to QuickBooks File Utilities.

• If you see “Host Multi-User Access,” click it.

• On workstations, ensure they do not host the file.

Still Not Working? Try These Advanced Fixes

• Reinstall QBDSM: Uninstall from the server, then reinstall using the QuickBooks installer.

• Run as Administrator: Always open QuickBooks and the Database Server Manager with admin rights.

• Update QuickBooks: Ensure both QuickBooks Desktop and QBDSM are updated to the latest version.

When to Contact Support

If these solutions don’t work and you continue experiencing:

• Repeated crashes

• .ND file corruption

• Persistent connection loss
  Then it’s time to contact QuickBooks Support or consult your IT administrator for deeper network troubleshooting.
