Troubleshooting Solutions to Fix QuickBooks Error H101

Now that we know the causes, let’s move on to the solutions. Here’s a step-by-step guide to troubleshoot and fix QuickBooks Error H101.

1. Verify Hosting Settings

The first step is to ensure that your hosting settings are configured correctly.

  1. On the Host Computer:

    • Open QuickBooks and go to the File menu.
    • Select Utilities.
    • If you see Host Multi-User Access on the list, it means that the host computer is not set up to host. Select this option to enable hosting.
    • If you see Stop Hosting Multi-User Access, it means hosting is already enabled. Do not change anything.

  2. On Workstations:

    • Open QuickBooks and go to the File menu.
    • Select Utilities.
    • If you see Stop Hosting Multi-User Access, click on it to disable hosting. Workstations should not have hosting enabled.

2. Configure Firewall Settings

Your firewall might be blocking QuickBooks from connecting to the server. To fix this:

  1. Create Firewall Exceptions:

    • Open the Control Panel and go to System and Security.
    • Click on Windows Firewall and select Advanced Settings.
    • Right-click on Inbound Rules and select New Rule.
    • Choose Port and click Next.
    • Select TCP and enter the following ports:
      • QuickBooks Desktop 2021: 8019, 56728, 55378-55382

    • Click Next and select Allow the Connection.
    • Complete the rule setup and repeat for Outbound Rules.

  2. Add QuickBooks to Exception List:

    • Go to Windows Firewall and select Allow an app or feature through Windows Firewall.
    • Click on Change settings and check QuickBooks on both Private and Public networks.

3. Check the .ND File

The .ND file is crucial for network access. If it’s damaged, you’ll need to recreate it.

  1. Locate the .ND File:

    • Go to the folder where your company file is stored.
    • Look for files with the extension .ND (e.g., CompanyName.qbw.nd).

  2. Rename the .ND File:

    • Right-click on the .ND file and select Rename.
    • Add .old to the end of the file name (e.g., CompanyName.qbw.nd.old).

  3. Rescan Using QuickBooks Database Server Manager:

    • Open QuickBooks Database Server Manager from the Start menu.
    • Click on Scan Folders and select the folder where your company file is stored.
    • Click Scan.
    • This will recreate the .ND file.

4. Restart QuickBooks Services

Ensuring that QuickBooks services are running properly can resolve the error.

  1. Open Services:

    • Press Windows + R to open the Run dialog box.
    • Type services.msc and press Enter.

  2. Restart QuickBooks Services:

    • Look for QuickBooksDBXX (where XX is your QuickBooks version) and QBCFMonitorService.
    • Right-click on each service and select Restart.
    • Ensure that the Startup type is set to Automatic.

5. Verify the IP Address and Network Configuration

An incorrect IP address can cause connectivity issues.

  1. Check IP Address:

    • On the server computer, open the Command Prompt.
    • Type ipconfig and press Enter.
    • Note down the IPv4 Address.

  2. Verify Network Configuration:

    • Ensure all computers are connected to the same network.
    • Use the ping command from the workstation to verify the server’s IP address (e.g., ping 192.168.1.1).

6. Use QuickBooks File Doctor

If the above steps do not resolve the issue, using QuickBooks File Doctor can help.

  1. Download and Install QuickBooks Tool Hub:

    • Visit the official QuickBooks website and download the QuickBooks Tool Hub.
    • Install the tool hub on your computer.

    • Click on Run QuickBooks File Doctor.
    • Select your company file and click Check your file.
    • Enter your QuickBooks admin password and click Continue.
