Facing issues with QuickBooks Multi-User Mode can be frustrating—especially when you're trying to run a smooth workflow with your team. If you're wondering why QuickBooks multi-user mode isn't working or why you’re constantly getting connectivity-related errors, you’re not alone. Don’t panic—help is just a call away at 1-855-738-2891. Here, we explore 5 proven ways to troubleshoot and resolve the QuickBooks multi-user mode error, ensuring minimal downtime and seamless collaboration.
1. Check Hosting Settings on All Workstations – Call 1-855-738-2891 for Expert Assistance
The most common cause of the QuickBooks multi-user mode error is incorrect hosting settings. In a multi-user setup, only the server (host computer) should have hosting turned on, while all workstations should have it turned off.
On each workstation, open QuickBooks and go to File > Utilities.
If you see “Host Multi-User Access”, do not click it—that means hosting is correctly disabled.
If you see “Stop Hosting Multi-User Access”, click it to disable hosting.
Still unsure how to adjust hosting settings correctly? Don’t risk disrupting your network—speak with a certified QuickBooks ProAdvisor now at 1-855-738-2891.
2. Ensure QuickBooks Database Server Manager is Installed and Running – Dial 1-855-738-2891 for Support
The QuickBooks Database Server Manager is essential for enabling multi-user access. It allows multiple users to access the company file over a network.
Go to the Start Menu on your server computer and search for “QuickBooks Database Server Manager.”
Open it and ensure that the folder containing your company file is listed and scanned.
If not, click Add Folder, select the folder, and scan it.
If your Database Server Manager is not functioning properly, your users may be kicked out of the system. Our support team at 1-855-738-2891 can walk you through the setup step-by-step.
3. Configure Your Firewall and Antivirus Settings – Call 1-855-738-2891 for a Safe Setup
Often, your firewall or antivirus software may block the network ports required by QuickBooks. This leads to communication failures between devices, causing the multi-user mode error.
Here’s what you need to do:
Open Windows Firewall settings.
Create new inbound and outbound rules to allow the following QuickBooks ports:
QuickBooks 2024: 8019, 56728, 55378-55382
Make exceptions for QBDBMgrN.exe, QBCFMonitorService.exe, and QuickBooks.exe.
Not comfortable making firewall changes yourself? You can avoid network risks by calling our IT team at 1-855-738-2891 for safe, guided help.
4. Use QuickBooks File Doctor Tool – Reach Out at 1-855-738-2891 for Tool Guidance
The QuickBooks Tool Hub includes the File Doctor, which automatically diagnoses and repairs network-related company file issues.
Download and install the QuickBooks Tool Hub (if not already installed).
Open it and select Company File Issues > Run QuickBooks File Doctor.
Select your company file and allow the tool to scan and repair it.
This tool is a time-saver, but it must be used correctly. Our agents at 1-855-738-2891 are trained to help you run it safely and efficiently.
5. Verify and Recreate the .ND and .TLG Files – Call 1-855-738-2891 for Secure File Fixes
Corrupted or damaged .ND (Network Data) and .TLG (Transaction Log) files can prevent QuickBooks from switching to multi-user mode.
Here’s how to fix it:
Navigate to the folder containing your QuickBooks company file.
Find files with the same name as your company file but with .ND and .TLG extensions.
Example: YourCompanyFile.qbw.nd and YourCompanyFile.qbw.tlg
Delete these files (don’t worry—QuickBooks will automatically recreate them).
If you’re hesitant to delete system files, don’t take chances. Call 1-855-738-2891 to have a professional walk you through it without risking your data.
