    Before you resolve the Multi-User Mode Issues

    To open your company file in multi-user mode or for other hosting operations, you must review the below steps which are responsible for smooth multi-user functioning.

    Check if the server computer went into sleep mode

    Ensure the QuickBooks server stays active to host your company file for workstation access. Check and adjust sleep settings if necessary.

    1. Go to Settings on your computer for Windows or MacOS.
    2. Find the sections on Energy Savers, Lock Screens, and Batteries.
    3. Go to any of the options visible on your screen.
    4. Look for Screen Timeout and change it to never.
    5. Choose and set your preferences and ensure the system isn’t set to go to sleep when it’s inactive.
    6. Once done, close the window.

    Ensure hosting mode is ON only on the host computer

    To ensure the multi-user mode functions properly, activate hosting mode on the server, not the workstation. Follow the below steps to enable hosting mode if it’s inactive:

    For the Workstation

    1. Launch QuickBooks on any of the workstations where you are having issues in multi-user mode.
    2. If your company file is open, sign out and go to the File menu.
    3. Then, choose Utilities.
    4. Now, if you see Host Multi-User Access, ignore it.
    5. Open QuickBooks on another workstation and check for the same. If you Stop Hosting Multi-User Access, select it.
    6. Repeat the same steps on each of your workstations.

    For Server Computer

    1. Ensure your QuickBooks company file is closed.
    2. Go to the File menu at the top and hover over to Utilities.
    3. If Stop Hosting Multi-User Access is an option, ignore it. If you see Host Multi-User Access, select it.

    Ensure QuickBooks Database Server Manager is Installed on the Server

    The QuickBooks Database Server Manager facilitates multi-user access to the company file over a network and enables multiple users to work together. Therefore, you must run the Database Server Manager on the main computer.

    If you don’t know, Database Server Manager is a part of the QuickBooks Desktop file, so you don’t need to download it separately. Proceed with the below steps to install it on the server: 

    Install Database Server Manager

    • Exit all the programs open on your server, including QuickBooks.
    • Go to the QuickBooks file folder and open the Setup_QuickBooks.exe file.
    • Follow the instructions displayed on your screen.
    • Find the product or license numbers:
      • Launch QuickBooks.
      • Tap on the F2 key. It will launch the Product Information window.
      • Find your product name, product number, and license number and note them down.
    • Now, QuickBooks will ask you to choose the installation type.
    • Choose the Custom or Network Options option and click Next.
    • From the below options, choose as per your network setup and click Next. Choosing any of the options will install the Database Server Manager
      • If you use Database Server Manager and QuickBooks Desktop on your server computer, click on I’ll be using QuickBooks Desktop on this computer, AND I’ll be storing our company file here so it can be shared over our network.
      • If you only use Database Server Manager on your server computer, click on I will NOT be using QuickBooks Desktop on this computer.
    • Follow the rest of the instructions displayed on your screen.
    • When it’s done, hit Install. Grant the permission if Windows asks to install it.

    Keep in mind that QuickBooks creates a new Windows user for each version of the Database Server Manager. For instance, Database Server Manager 2023 will show up as QBDataServiceUser33.

    Also, don’t forget to give the folder permission to QBDataServiceUserXX.

    Configure Database Server Manager

    You can also skip this section if you want to continue with the default settings.

    1. Press the Windows logo key to open the Windows Start menu.
    2. Search for Services and open Services from the search results.

    Before adding the QuickBooksDBXX and QBCFMonitorService to the Windows admin group, you must check if the folder is set up correctly; here’s how to do it:

    Verify that permissions are set correctly

    2. Find your company file folder and right-click on it.
    3. Choose Properties and go to Sharing.
    4. Then, click on Share Add

    When you’re done, launch QB on the server computer and workstations. If you are still facing multi-user mode issues, move to the next solution.

    Configure Windows Firewall settings on your server

    Windows firewall is a security application that blocks any malware on your computer. Similarly, it might consider QuickBooks or its program files as a threat and can cause issues in multi-user mode.

        Note: QuickBooks Desktop 2019, 2020, and other future versions use dynamic ports. However, for the prior version, specific ports were assigned during installation. It ensures QuickBooks Desktop gets exclusive use of the given port.
        Get the Dynamic Port of QB 2020 or later versions:
      • Launch the Windows Start menu.
      • In the search field, enter QuickBooks Database Server Manager and open the same.
