This problem can disrupt workflow, reduce productivity, and cause confusion across your accounting team.
If you're currently facing this issue, don’t worry. This detailed, step-by-step guide will walk you through troubleshooting and resolving the error. Whether you're using QuickBooks Pro, Premier, or QuickBooks Desktop Payroll Subscription, this guide will help you regain access to multi-user functionality quickly.
What Causes QuickBooks Multi-User Mode to Stop Working?
Before diving into the solutions, it's crucial to understand why QuickBooks Multi-User Mode Not Working errors occur. The most common causes include:
Improper hosting settings
Windows Firewall or third-party firewall blocking communication
Damaged or missing Network Data (.ND) files
QuickBooks Database Server Manager not running on the server
DNS or network configuration errors
Conflicts with QuickBooks Desktop Payroll Subscription services
Understanding these causes can help you apply the right fix more effectively.
Step-by-Step Guide to Fix QuickBooks Multi-User Mode Not Working
Step 1: Check Hosting Settings on All Workstations
Only the server should have hosting enabled.
How to check:
Open QuickBooks on all workstations.
Go to File > Utilities.
If you see "Host Multi-User Access", do nothing.
If you see "Stop Hosting Multi-User Access", click it to disable hosting on that workstation.
Repeat this process on every computer except the main server.
Step 2: Use QuickBooks Tool Hub to Automatically Diagnose
The QuickBooks Tool Hub is your best friend when facing connectivity and file issues.
Steps:
Download the latest version of QuickBooks Tool Hub from the official site.
Install and open the application.
Navigate to Network Issues > QuickBooks Database Server Manager.
Scan your company file folder for any issues.
This tool will automatically detect and fix many network-related problems.
Step 3: Ensure QuickBooks Database Server Manager is Running
On your server computer:
Press Windows + R, type services.msc, and hit Enter.
Locate QuickBooksDBXX (where XX is your version, like QuickBooksDB30 for 2020).
Ensure the service is running. If not, right-click and choose Start.
Without this service, multi-user access cannot function.
Step 4: Configure Windows Firewall and Antivirus Software
Sometimes, firewall settings block QuickBooks from connecting in multi-user mode.
Open Control Panel > System and Security > Windows Defender Firewall.
Click Allow an app or feature through Windows Defender Firewall.
Ensure that QuickBooks and QuickBooksDBXX are both allowed on private and public networks.
If you're using third-party antivirus software, check its settings or temporarily disable it and test multi-user mode again.
Step 5: Verify Folder Permissions on the Server
The folder containing your company file must have full permissions.
Steps:
Right-click the folder > Properties > Security.
Check that users have Full Control.
If not, click Edit and modify the permissions accordingly.
Improper folder permissions can block access to the company file in multi-user mode.
Step 6: Ping the Server from a Workstation
This step checks network connectivity between the server and workstations.
How to ping:
On a workstation, press Windows + R, type cmd, and press Enter.
Type ping [server-name] and press Enter.
If the ping fails, you have a network issue. Restart your router or consult your network administrator.
Step 7: Create a New .ND File
The Network Descriptor (.ND) file allows QuickBooks to access company files over a network.
Steps:
Go to the folder where your company file is stored.
Find and delete the .ND file (e.g., companyfile.qbw.nd).
Open QuickBooks Database Server Manager from Tool Hub and rescan the folder.
This will automatically create a new and clean .ND file.
Extra Tip: Check Compatibility with QuickBooks Desktop Payroll Subscription
If you’re using QuickBooks Desktop Payroll Subscription, ensure it's fully updated. Outdated payroll modules can conflict with multi-user mode, especially when files are shared across users.
Go to Help > Update QuickBooks Desktop > Update Now.
Select Get Updates, then restart QuickBooks and install the updates.
Also, ensure that all users on the network are using the same version of QuickBooks to avoid data sync issues.
