What Is QuickBooks Error H202?

QuickBooks Error H202 typically occurs when you try to open your QuickBooks company file in multi-user mode, but QuickBooks cannot reach the server computer that hosts the file.

Error Message:

“This company file is on another computer, and QuickBooks needs some help connecting.”

This error is part of the H-series (H101, H202, H303, and H505) and is directly tied to network-related issues. Error H202 specifically means your workstation is unable to connect to the company file on the server.

Causes of QuickBooks Error H202

Before you jump into solutions, it’s important to understand why QuickBooks Error H202 occurs. Here are the most common causes:

• Blocked QuickBooks Communication – The Windows firewall or a third-party security application is blocking data exchange between the workstation and server.
• Incorrect Hosting Configuration – QuickBooks hosting settings might be misconfigured on one or more computers.
• Damaged .ND File – The Network Data (.ND) file is corrupt or misconfigured.
• QuickBooksDBXX Service Not Running – This service is necessary for database operations and connectivity.
• DNS Server Issues – Incorrect or unreachable DNS server entries can block access to the host computer.
• Incorrect IP Address or Server Name – The workstation may be using the wrong IP or server alias.

How to Fix QuickBooks Error H202: Step-by-Step Solutions

Let’s now look at effective solutions to eliminate QuickBooks Error H202.

Solution 2: Verify Hosting Settings

Incorrect hosting settings can create conflicts between your workstation and the server.

Steps:

• Open QuickBooks on the server computer.
• Go to File > Utilities.
• If you see “Host Multi-User Access”, that’s good — do not click it.
• If you see “Stop Hosting Multi-User Access”, click it.

Do the same on each workstation and make sure hosting is only enabled on the server.

Solution 3: Check Windows Firewall Settings

Your firewall might be blocking necessary ports used by QuickBooks.

Steps:

• Open Control Panel > System and Security > Windows Defender Firewall.
• Click Advanced Settings > Inbound Rules > New Rule.
• Select Port and click Next.
• Add the following QuickBooks ports:
• QuickBooks Desktop 2024: 8019, 56728, 55378-55382
• Allow the connection and finish the setup.

Repeat for Outbound Rules as well.

Pro tip: Use the QuickBooks File Doctor (inside Tool Hub) to automate this.

Solution 4: Rename the .ND File

The .ND (Network Data) file may be corrupted. Renaming it forces QuickBooks to generate a fresh one.

Steps:

• Go to the folder where your company file is stored.
• Locate the file with the .ND extension (e.g., CompanyName.qbw.nd).
• Right-click and choose Rename.
• Add .old at the end of the filename (e.g., CompanyName.qbw.nd.old).
• Restart QuickBooks and attempt to access the company file again.

Solution 5: Ping the Server from Your Workstation

This ensures the workstation can actually reach the server.

Steps:

• On your workstation, press Windows + R and type cmd, then hit Enter.
• Type: ping [servername] (e.g., ping QBServer)
• If you get reply responses, the connection is working. If not, you may have a network configuration problem or DNS issue.

Additional Advanced Fixes

If the above steps don't resolve Error H202, try these:

• Check DNS Settings – Manually configure DNS to point to the correct server IP.
• Add Server to Windows Hosts File – Add an entry in the hosts file with your server’s IP and name.
• Restart QuickBooksDBXX and QBCFMonitorServices – Make sure these services are running on the server.
