Can the QBDataServiceUser31 password be reset?


I am trying to troubleshoot a QuickBooks issue for a client. Customer is using QuickBooks Enterprise Solutions 21.0 however they cannot open a company file in multi-user mode. I believe the issue is with the QuickBooksDB31 service. It will not start. When I check the logs it says, "The QuickBooksDB31 service failed to start due to the following error: The service did not start due to a logon failure." I presume the password for the QBDataServiceUser31 account (which is what is used to run the service) was changed somehow. The account is not locked out. Is it safe to change this password? Or perhaps delete the account? If account gets deleted, will QB automatically recreate the account and enter the credentials in the QuickBooksDB31 service? please advise.

Thank you.

Can the QBDataServiceUser31 password be reset?

Thanks for taking the time to post here in the Community, VC31326. I know how challenging it is when your client can't open the company file. I'm here to assist you with that.


Since the QuickBooksDB31 service will not start, let's recreate the QBDataServiceUserXX. This way, your client can access their QuickBooks data. I'll show you how:


  1. Close QuickBooks.
  2. On your keyboard, press Windows key+R to bring up the Run window.
  3. Type services.msc, then press Enter.
  4. Right-click the service that matches your version, then choose Properties.
    • QuickBooks 2020: QuickBooksDB30
    • QuickBooks 2019: QuickBooksDB29
    • QuickBooks 2018: QuickBooksDB28
  5. Go to the Log On tab, then set the service to This Account.
    Note: Do not select Local System. Only some set-ups allow it to work on Local System.
  6. Delete qbdataserviceuserXX:
    1. On your keyboard, press Windows key+R to open the Run window.
    2. Type Control Panel, then select OK.
    3. Select User Accounts, then Remove user account.
    4. Select the qbdataserviceuserXX that matches your version, then Delete.
  7. Relaunch QuickBooks.
    Note: If hosting was started, turn it off then turn it back on again. If hosting wasn't started, turn it on.
  8. When a prompt asking to run Database Server Manager pops up, select OK.
  9. Open the Database Server Manager and scan the file. This recreates the qbdataserviceuser.


For more details about the process, please see this article: Database Manager Service.

I'm preparing to help someone with this problem and steps to select the service and click "Log On" seem to be just an exercise. Is there something do once you click the "Log On" tab?


Someone recently ran a password reset tool on our QB server and we've lost multiuser access to the DB. When we open QB on either the server or a second machine it goes through a repair process and that locks out the other machine.

Hello ecsproull,


Let's isolate if the cause of the issue is a damaged QuickBooks Database Server Manager. I'm here to help resolve the issue so you can access Multi-User Mode.


To start with, let's turn on hosting. Here's how:


  1. Click the File menu.
  2. Under Utilities, select Host multi-user access.
  3. On the Host multi-user access window, select Yes.


If the same issue persists, let's configure the services. You can follow these steps:


  1. Open the Run window by pressing the Windows on your keyboard.
  2. Type services.msc, then press Enter.
  3. In the services window, look for the QuickBooksDBXX service that matches your version:
  4. QuickBooks 2020: QuickBooksDB30
  5. QuickBooks 2019: QuickBooksDB29
  6. QuickBooks 2018: QuickBooksDB28
  7. Double-click the QuickBooksDBXX service.
  8. Set the Startup Type to Automatic and Service Status to Running or Started. Go to the Recovery tab.
  9. From the First failure drop-down, select Restart the Service. This automatically restarts the QuickBooksDB service if it fails. Do the same for Second failure and Subsequent failures.
  10. Select OK to save the changes. Then, reboot your computer.


If you're still unable to access the Multi-user mode, proceed to Solutions 3 and 4 in this article: The QuickBooksDBXX service on the Local Computer started and then stopped.

You can always post in the forum whenever you have concerns about accessing multi-user mode.
