Routine Problems & Quick Repairs

Make sure the “Server” network profile is Private and NOT Public, and that all Advanced Network Sharing options are on and Password Access is off.
Make sure the QuickBooks Database Server Manager is running on the client’s “Server” computer and select the “Scan” button when the programs open; the scan itself can find and fix a large number of basic/minor issues with QuickBooks and QuickBooks network hosting.
Make sure the QuickBooks Services (Run → Services.msc) are all set to start Automatically, and under their Recovery Tab (in Properties) make sure “Restart on Failure” is set for all 3 restart options if the service(s) were to stop.
- QuickBooksDBXX Service Name: QuickBooksDB32 or QuickBooksDBXX (Where XX = Year version of QuickBooks, e.g., QuickBooksDB31 for QB 2021)
- QBCFMonitorService Service Name: QBCFMonitorService
Create a scheduled task in the Windows “Task Scheduler” to make sure the QuickBooks Database Server Manager application auto-starts for the following triggers:

Computer Starts (1 minute delay)
User Login (30-second delay)
The system wakes up from sleep
System is Idle

Advanced Troubleshooting & Repairs

1. Verify System & Network Requirements

Make sure all systems (host/server and workstations) meet QuickBooks system requirements.
Confirm that QuickBooks Desktop Database Server Manager is installed and running on the host computer.
Ensure Windows is up to date, and QuickBooks updates are installed on all systems.

2. Check Folder Permissions

The folder containing the company file (.QBW) All users who access it must have full read/write permissions.
Right-click the folder > Properties > Security tab > ensure Everyone or QBDataServiceUser has Full Control.
Double-check that the company file is shared correctly on the network.

3. Run the QuickBooks File Doctor Tool

Download and run QuickBooks Tool Hub (from official Intuit support).
Use File Doctor from the Tool Hub to scan and repair:
- Company file corruption
- Network connectivity issues

4. Verify Hosting Settings

On each computer:

Open QuickBooks > File > Utilities:
- On the server, it should say “Host Multi-User Access.”
- On workstations, it should not say “Stop Hosting Multi-User Access.” If it does, turn it off.

5. Use QuickBooks Database Server Manager

Open QuickBooks Database Server Manager on the host computer.
Click "Scan Folders" and add the folder that contains the company files.
This creates proper .ND (network descriptor) files and allows the server to host the company files for multi-user access.

6. Check Windows Firewall and AV Software

Make sure firewall ports for QuickBooks are open:
- TCP: 8019, 56728-56730 (for QuickBooks 2021–2024)
- Also, allow exceptions for:
  - QBDBMgrN.exe
  - QBW32.exe
  - FileManagement.exe
Add exclusions to the antivirus for the QuickBooks folder and services.

7. Map a Network Drive (Optional but Recommended)

Map a network drive to the folder containing the company file.
Use the mapped drive path (e.g., Z:\\CompanyFiles\\YourCompany.QBW) to open the file.

8. Test Network Connectivity

Try pinging the server by hostname from each workstation.
Use \\\\ServerName\\SharedFolder to test access.
If this fails, check network sharing settings and any third-party security software.

9. Rebuild/Verify the Company File

Open company file > File > Utilities > Verify Data
If errors are found, run Rebuild Data from the same menu.

10. Multi-User Mode Test

Open QuickBooks on multiple workstations.
Open the company file in Multi-user Mode.
Go to File > Switch to Multi-user Mode and test concurrent access.
