What Does the QuickBooks Multi-User Company File Error Mean?

This error appears when QuickBooks on a workstation cannot establish a connection to the company file hosted on another computer or a server. It usually occurs in networked environments where more than one user needs simultaneous access to the same data file.

QuickBooks displays errors like:

• “Error H202: This company file is on another computer, and QuickBooks needs help connecting.”
• “QuickBooks cannot open the company file in Multi-User mode.”

Major Causes of QuickBooks Multi-User Company File Error

1. Incorrect Hosting Setup
2. Only the server or main computer should host multi-user access. Multiple systems trying to host can lead to conflicts.
3. Firewall or Security Software Blocking Connection
4. Windows Firewall or third-party security software may block QuickBooks ports required for network communication.
5. QuickBooks Database Server Manager Not Running
6. The QuickBooks Database Server Manager allows multiple users to access the same file. If it’s not installed or running, workstation connections will fail.
7. Damaged Network Data (.ND) File
8. The .ND file connects QuickBooks to the network. Corruption or misconfiguration in this file prevents users from connecting to the company file.
9. DNS or Network Configuration Issues
10. Weak network signals, incorrect DNS setup, or IP address mismatches between server and clients can trigger this error.
11. Incorrect Folder Permissions
12. If the user doesn’t have read/write access to the company file folder, QuickBooks cannot establish a multi-user connection.

Step-by-Step Fixes for QuickBooks Multi-User Errors

Step 1: Verify Hosting Settings

• Open QuickBooks Desktop on each workstation.
• Go to File > Utilities.
• If you see Host Multi-User Access, do not select it (it means hosting is off, which is correct for workstations).
• On the server computer, ensure Stop Hosting Multi-User Access is visible, meaning hosting is active only there.

Step 2: Run QuickBooks Database Server Manager

• On the server computer, open QuickBooks Database Server Manager from the Windows Start menu.
• Select Scan Folders and add the directory where your company file (.QBW) is located.
• Click Start Scan and wait until the scan completes.
• Once done, restart both QuickBooks Database Server Manager and QuickBooks Desktop.

Step 3: Configure Windows Firewall

• Go to Control Panel > Windows Defender Firewall > Advanced Settings.
• Create Inbound and Outbound Rules for QuickBooks executable files: QBDBMgrN.exe, QBW32.exe, FileManagement.exe.
• Allow TCP ports 8019, 56728, 55378–55382 (for QuickBooks 2022/2023/2024 versions).
• Restart your computer to apply changes.

Step 4: Rename the .ND File

• Browse to the folder where your company file is stored.
• Find the file with the same name as your company file but ending with .ND (for example, YourCompanyFile.qbw.nd).
• Right-click and choose Rename, then add .old to the end of the file name.
• Open QuickBooks again and rescan using Database Server Manager.

Step 5: Use QuickBooks File Doctor Tool

• Open the QuickBooks Tool Hub.
• Go to the Company File Issues tab.
• Run QuickBooks File Doctor, select your company file, then choose Check your file and network.
• This will repair connectivity and minor file errors automatically.

Step 6: Verify Folder Permissions

Ensure each user has Full Control access to the folder containing the company file.

• Right-click the folder and select Properties > Security tab.
• Choose Advanced > Add > Select Principal, assign Full Control, and click Apply.

After completing these steps, reopen QuickBooks in multi-user mode to confirm if the error is resolved.

Prevention Tips

• Keep QuickBooks Database Server Manager always updated.
• Store company files only on a dedicated server computer.
• Ensure all systems use the same QuickBooks Desktop version.
• Regularly update Windows Firewall settings and QuickBooks ports.
• Avoid turning on hosting mode on workstations.
• Always close QuickBooks properly before shutdown.

Frequently Asked Questions 

1. What is QuickBooks Error Code H202?

Error H202 occurs when QuickBooks Desktop cannot connect to the company file stored on another computer due to network or configuration issues.

2. Can I fix multi-user mode issues without the Database Server Manager?

It means hosting is enabled. Only the server should show this option; workstations should show “Host Multi-User Access.”

4. Do I need to open ports for QuickBooks multi-user mode?

Yes. Certain QuickBooks versions require specific TCP ports to be allowed through Firewalls to maintain network communication.

5. How do I prevent future multi-user connection problems?

Keep QuickBooks updated, set network permissions correctly, and ensure consistent connectivity between all computers on the network.
