Running QB's off a NAS in Multi-user Mode

WARNING: The first user to open QBs hosts multi-user mode. If the first person that opens QBs closes QBs everyone that opened it after will lose access and have to reopen QBs.

If you are getting an H202, H303, H505, H101 or any other error relating to Multi-User access for QuickBooks 2015 or later, perform the following:

    1. Ensure QuickBooks 2015 or later is installed on your server or computer acting as the QuickBooks host.
    2. Open the Start menu, select All Programs, QuickBooks, then select QuickBooks DataBase ServerManager.
    3. In the QuickBooks Database Server Manager, ensure the folder that contains your company files is showing (if not, click Browse and browse to the location you store your file on your C:\ or D:\).
    4. Click the Start Scan button and wait until the process finishes.
    5. Try opening QuickBooks in Multi-User Mode on your workstations to ensure the problem is resolved.


  1. Try opening QuickBooks in Multi-User Mode on your workstations to ensure the problem is resolved.


If you wish to enable the Alternate Setup Mode (for NAS drives or similar devices and if you run into problems with MU mode:

Note: The following steps are technical in nature, if you are not comfortable with them, please reach out to a qualified computer professional or IT person.

On each workstation computer, you will need to perform the following steps. You do not need to edit anything on the server or NAS drive for these steps, just the workstations that are getting H202 errors.

    1. Make sure QuickBooks is closed and the QBW32.exe is not running in the task manager.
    2. Navigate to C:\ProgramData\Intuit\QuickBooks 2015 (or 2016).
    3. Edit the QBW.ini file in notepad.
    4. Type ENABLENONRECOMMENDEDMODE=1 directly under the [MISC] section. It should look like this...

    1. Now save the QBW.ini file and open QuickBooks and try to switch to Multi-User mode.
    2. When you get the H202 error again, if you edited the ini file correctly, you should see the Alternate Setup button has returned.

  1. Click the Alternate Setup button and press Yes to any proceeding UAC messages and QuickBooks should now work in the alternate setup mode and Mult-User access restored.

Important: It is important to note, that while the company file may be stored on a server or NAS drive using Alternate Setup Mode, whoever opens the file in MU mode first and clicks Alternate Setup becomes the host. If that person who is hosting the file on their workstation reboots or logs off while others are working in the file, QuickBooks will kick the other users out of the file and may loose the work they were doing prior to the crash. If you are using a NAS or similar device, to maintain optimal stability, you will need to use QB on a Windows machine so the database manager can be installed properly. Otherwise, you can enable alternate setup mode at your own risk and be mindful of who is going to press the Alternate Setup button as they will become the host and they cannot log off/reboot/shutdown until all others are out of the file.


If you continue to run into problems, see the Error H101, H202, H303, or H505: when opening your company filearticle for further troubleshooting steps.
