What is Multi-User Mode in QuickBooks?
Multi-User Mode allows multiple users to access a QuickBooks company file at the same time. It’s designed to improve productivity and allow collaborative bookkeeping, especially in office environments where several users work in QuickBooks simultaneously.
When this feature fails, it typically means your system’s network settings or hosting configuration needs attention.
Common Symptoms
When QuickBooks Multi-User Mode is not working, you might experience:
QuickBooks switches back to single-user mode automatically
Error messages when trying to open the company file
Inability to connect to the server hosting the file
Sluggish performance when attempting to enable multi-user access
Main Causes of Multi-User Mode Not Working
There are several potential causes behind this issue:
Incorrect hosting settings on workstations
Disabled QuickBooks services (QBCFMonitorService or QuickBooksDBXX)
Firewall or security software blocking communication
Damaged .ND (Network Data) file
Issues with QuickBooks Database Server Manager
Network connectivity issues
Top Solutions to Fix QuickBooks Multi-User Mode Not Working
Let’s walk through proven methods to fix this frustrating error.
1. Check Hosting Settings on Each Computer
Only the server or main host computer should have hosting turned on.
Steps:
Open QuickBooks on each workstation
Go to File > Utilities
If you see Host Multi-User Access, do not click it
If it shows Stop Hosting Multi-User Access, click it to disable hosting on that system
2. Use QuickBooks Database Server Manager
The Database Server Manager helps maintain multi-user connections.
Steps:
Open QuickBooks Tool Hub
Click on Network Issues
Select QuickBooks Database Server Manager
Scan the folder that contains your company file
Restart your system and check multi-user mode again
3. Restart QuickBooks Services
Ensure QuickBooks-related services are running on the server.
Steps:
Press Windows + R, type services.msc, and hit Enter
Locate QuickBooksDBXX and QBCFMonitorService

4. Configure Windows Firewall & Security Software
Firewalls often block the ports QuickBooks uses to operate in multi-user mode.
Steps:
Open Windows Defender Firewall
Click Allow an app or feature through Windows Firewall
Ensure QuickBooks and its ports (8019, 56728, 55378-55382) are allowed
Manually add exceptions for QuickBooks if necessary
5. Rename the .ND File
Corrupted network data files can interrupt QuickBooks’ ability to connect to the company file.
Steps:
Navigate to your QuickBooks company file folder
Find the file with a .ND extension (e.g., YourCompanyFile.qbw.nd)
Right-click > Rename > Add .old at the end
Reopen QuickBooks and attempt multi-user access again
6. Use QuickBooks File Doctor
The File Doctor tool scans and fixes many common network and company file issues.
Steps:
Download and open QuickBooks Tool Hub
Go to Company File Issues
Launch QuickBooks File Doctor
Choose your file and let it diagnose the problem
7. Check Folder Permissions
The folder containing your company file must be shared with full control.
Steps:
Right-click the folder > Properties
Go to the Sharing tab and click Advanced Sharing
Ensure Share this folder is selected
Click Permissions and grant Full Control to all users
8. Ping the Server
Test connectivity between workstations and the host computer.
Steps:
On a workstation, open Command Prompt
Type ping [servername] (replace with actual server name)
