How to Fix QuickBooks Error H101

This error generally appears when you try to access company files located on another computer and requires specific network setup adjustments for multi-user mode. Here, we'll explore detailed steps to resolve QuickBooks Error H101, ensuring your operations run smoothly without unnecessary downtime.

Understanding Error H101

QuickBooks Error H101 indicates that the computer where the QuickBooks company file is located needs additional configuration to allow other computers on the network to access the file. It’s typically triggered by:

Incorrect hosting configuration.
Issues with the DNS settings.
Firewall settings prevent communication.
Faulty or incorrect network data (.ND) file setup.

Preliminary Checks

Before diving into more technical fixes, ensure basic connectivity:

Verify that all computers are on the same network.
Check if you can access the internet and other network resources from each computer.
Restart your QuickBooks on all involved machines, sometimes a simple restart can resolve the issue.

Step 1: Verify Hosting Settings

QuickBooks Error H101 often arises when multiple computers are set to host the company files. Only the server, i.e., the main computer holding the company files, should host the mode.

On each workstation (not the server):

Open QuickBooks and go to ‘File’ ‘Utilities’.
If you see an option that says ‘Host Multi-User Access’, don’t select it. This means this computer is not hosting the file and it’s correct.
If it says ‘Stop Hosting Multi-User Access’, select this option to disable hosting here.

On the server computer:

You should see ‘Host Multi-User Access’. If not, select it to enable hosting.

Step 2: Configure the Firewall

Incorrect firewall settings can block communication between computers trying to access company files, leading to Error H101.

Update your firewall to the latest version to avoid any compatibility issues.
Configure the firewall settings:

Go to the firewall settings and allow permissions for QuickBooks programs on the server and workstations.
Ensure that ports 8019, 56728, 55378, and 55382 are open for both incoming and outgoing traffic.

If you are unsure how to do this, you can use the QuickBooks File Doctor tool, which can help automatically configure your firewall.

Step 3: Check the Services

QuickBooks services like QuickBooksDBXX and QBCFMonitorService must run on the server computer. Here’s how to check:

Press Windows + R, type services.msc, and press Enter.
Scroll down and find QuickBooksDBXX (XX denotes the version).
Double-click it, and ensure the Startup Type is set to ‘Automatic’ and the service status is ‘Running’.
Repeat the same steps for QBCFMonitorService.

Step 4: Create a New Folder for Your QuickBooks Company File

If the above steps don’t resolve the error, try creating a new folder on the server and sharing it with full access permissions:

Create a new folder on a shared drive.
Copy the QuickBooks company file (.QBW) to the new folder.
Right-click the new folder and select ‘Share with’ ‘Specific people...’, and add all users with permission level set to ‘Read/Write’.

Step 5: Use QuickBooks File Doctor

QuickBooks File Doctor is a tool developed by Intuit to help resolve common network and company file issues. It can automatically diagnose and fix a range of network issues, including Error H101. To use it:

Download and install QuickBooks Tool Hub.
