Method 1.1: Download and Install QuickBooks Tool Hub

It is recommended to download the most recent version of QuickBooks Tool Hub on your Windows 10 (64-bit).

• Click on the Windows search bar located on the bottom left.
• Type “QuickBooks Tool Hub” in the search bar.

• Launch “QuickBooks Desktop” and your “QB Company file”.

This is how you can install and run QuickBooks Tool Hub on your computer. This will resolve the QuickBooks error H101 related to company files or QuickBooks software.

Method 2: Run QuickBooks Database Server Manager

In case you are facing problems associated with the network connection or receiving an H101 error in QuickBooks then you should run QuickBooks Database Server Manager. This can be used by performing QuickBooks Tool Hub. Let’s know how to use it:

• Click on the Windows search bar located on the bottom left.
• Type “QuickBooks Tool Hub” in the search bar.
• Choose the “Network Issues” tab on the left.

• Open the “QuickBooks Database Server Manager”.
• If you see the correct location of your QB company file then click the “Start Scan” button. If not, then go to the “Browse” button, pick your correct company file, and hit the “Start Scan” button.

Once you initiate the process, the QuickBooks Database Server Manager starts repairing the firewall and grants permission to access files.

After the process is finished, you can close the window and launch QuickBooks to verify if you can access the company files. To do so, go to the File button and click on the Switch to Multi-User Mode.

Method 3: Stop Hosting Multi-User Access

If you confront QuickBooks error H101 on more than one workstation, it is an indication that multi-user mode is enabled on other workstations besides server host. One has to remember that the server must be the only device where you have enabled the multi-user mode.

Therefore, it is advised that you disable host multi-user mode on the workstation. Follow these steps for that:

• Launch the “QuickBooks” software on which you are receiving QuickBooks error H101.
• Now, go to the “File” option.
• Click the “Utilities” option.
• Here, if you see the “Stop Hosting Multi-User Access” option then you need to select it. But if you find “Host Multi-User Access” then you don’t need to select this option.

Note: You will see the Stop Hosting Multi-User Access option only if it is enabled otherwise you will find the option to host the mode.

Users have to follow the same steps for other workstations where the multi-user mode is accessible.

Once done with the other workstations, you can move to your server device. This should be the only device where you should host the company file.

To host QuickBooks company file with your server device, you can do the following:

• Launch “QuickBooks” software.
• Now, go to the “File” option.
• Click the “Utilities” option.
• Here, if you see the “Host Multi-User Access” option then you need to select it and follow the prompts on your screen.
• In case you see “Stop Hosting Multi- User Access” then you don’t need to select this option.

By following these steps, you will disable the host multi-user mode from other workstations and enable it only for the server computer. 

Method 4: Adjust Firewall Settings

Windows Defender Firewall often blocks certain apps and programs to perform. This could be the reason that you are failing to access the company files. Hence, in this method, we will allow the app through the Windows Defender:

• Press the “Windows + R” keys to open the “Run” dialog box.
• Type “Control Panel” in the text field.
• Hit the “OK” button.
• Click on the “System and Security” link.
• Then, click on the “Windows Defender Firewall” option.
• Here, you can select “Allow an app or feature through Windows Defender Firewall” located on the left.
• Now, allow “QuickBooks app” from the list of programs.
• Hit the “OK” button.

After you allow QuickBooks service, you can continue accessing the company files. If you are still bothered by the H101 QuickBooks error then switch to the next step.

Method 5: Change the Company File Location

By changing the QuickBooks company file location, you can fix the QuickBooks error H101. Here is how to do this:

• First of all, make a new folder.
• Copy your company file and paste it into the new folder that you created.
• Now, launch the “QuickBooks” app.
• Click on the “File” button.
• Select the “Open a Company File”’ option.
• Hit the “Next” button.
• Now, browse the new folder in which your company file is saved.
• Hit the “Open” button.

This way you can open the company file from the new location. But, remember that these steps should be performed on the computer where your company file is hosted.

Method 6: Check QuickBooks Services

If QuickBooks services such as QBCFMonitorService.XX and QuickBooksDBXX don’t run on your server then QuickBooks error H101 is likely to appear. In this method, we will enable QuickBooks services if not running:

• Make sure QuickBooks Desktop is closed.
• Press the “Windows + R” keys to open the “Run” dialog box.
• Type “Services.MSC” in the text field.
• Hit the “OK” button.
• Search for “QuickBooksDBXX” under the “Services” and double click on this.
• Select the “Automatic” option under the “Startup Type”.
• Here, you need to ensure that the “Service” status displays as “Running”.
• Then, switch to the “Recovery” tab.
• Click on the “Restart the Service” located under the “First Failure, Subsequent Failure, and Second Failure”.
• Hit the “Apply” and “OK” buttons respectively.

This is how you can restart the stopped services for QuickBooks. Similarly, you can do it for the QBCFMonitorService. Once you are done, do the following:

• Open “QuickBooks” software.
• Click on the “File” menu.
• Click on the “Switch to Multi-User Mode”.

After following all these steps, if you are able to access your company file on the workstation and server then it indicates your problem has been resolved.
