Running a business requires real-time collaboration—and that’s where QuickBooks Multi-User Mode comes in handy. But when QuickBooks multi-user mode is not working, it can disrupt productivity and prevent your team from accessing important files.
In this article, we’ll walk you through why it happens, how to fix it, and when to call for help at +1 855-749-2321.
What is Multi-User Mode in QuickBooks?
Multi-user mode in QuickBooks allows multiple users to access the same company file simultaneously. It’s ideal for businesses with accountants, bookkeepers, and team members working together. But when it fails, users get errors like:
“Cannot connect to the company file.”
“QuickBooks is unable to open this company file.”
“H202 or H505 Error”
Why QuickBooks Multi-User Mode Is Not Working
There are several reasons why QuickBooks fails to switch or function in multi-user mode:
Incorrect hosting settings on the server
QuickBooks Database Server Manager not running
Windows firewall or antivirus blocking network ports
Damaged .ND file (Network Data file)
Poor network configuration
Missing or disabled QBDBMgrN service

How to Fix QuickBooks Multi-User Mode Not Working
1. Verify Hosting Settings on Each System
Open QuickBooks on each workstation.
Go to File Utilities.
Make sure only the server system shows “Host Multi-User Access”. Others should display “Stop Hosting Multi-User Access”.
If it’s incorrectly set on more than one system, QuickBooks will not work in multi-user mode.
2. Use QuickBooks File Doctor via Tool Hub
Download and install the QuickBooks Tool Hub.
Select Network Issues QuickBooks File Doctor.
Let the tool scan and repair the company file and connection.

3. Restart QuickBooks Database Server Manager
Press
Windows + Rtype services.msc.Locate and restart QuickBooksDBXX (XX = version year).
Set it to Automatic.
This service must be running on the server for multi-user mode to work properly.
4. Check Windows Firewall Settings
Ensure QuickBooks ports are allowed in your firewall:
QuickBooks 2024: Port 8019
QuickBooks 2023: Port 8019
QuickBooks 2022: Port 8019
Manually add exceptions or call +1 855-749-2321 for assistance.
5. Rename the .ND File
Go to the folder where your company file is stored.
Find the .ND file (e.g.,
CompanyFile.qbw.nd).Rename it to
CompanyFile.qbw.nd.old.
QuickBooks will recreate it automatically when reopened in multi-user mode.
6. Ping the Server from Workstations
Check network connection:
On each workstation, open Command Prompt and type:
ping [ServerName]
If there’s no response, your computer isn’t communicating with the server. Fix network issues or call +1 855-749-2321.
