What Is QuickBooks Error H202?

QuickBooks Error H202 typically arises in a multi-user environment. It means that the workstation you're using cannot access the company file on another computer (usually the server). This is often caused by network problems, firewall restrictions, or misconfigured hosting settings.

Error Message:“You are trying to work with a company file located on another computer, and this copy of QuickBooks cannot reach the server (H202).”

Common Causes of QuickBooks Error H202

1. Blocked Ports by Firewall: QuickBooks requires specific ports to function properly. If these are blocked, the connection will fail.

2. Incorrect DNS Settings: Domain Name System (DNS) misconfigurations can prevent QuickBooks from locating the server.

3. Damaged .ND File: The network data (.ND) file may be corrupted or misconfigured.

4. QuickBooks Services Not Running: Essential services like QuickBooksDBXX or QBCFMonitorService may be inactive.

5. Improper Hosting Configuration: Hosting should be turned on only on the server computer, not on workstations.

Proven Fixes for QuickBooks Error H202

Let’s walk through the step-by-step methods that have helped countless users eliminate this error:

1. Use the QuickBooks Database Server Manager

The QuickBooks Tool Hub comes with a built-in Database Server Manager that scans and fixes hosting issues.

Steps:

1. Download and install the QuickBooks Tool Hub.

2. Open it and click on Network Issues.

3. Select QuickBooks Database Server Manager.

4. Scan the folder where your company file is located.

5. Restart the QuickBooks services.

This tool automatically repairs common multi-user setup issues.

2. Verify and Configure Hosting Settings

Ensure that only the server hosts the company file.

On your workstation:

• Open QuickBooks and go to File > Utilities.

• If you see “Host Multi-User Access,” do nothing.

• If it says “Stop Hosting Multi-User Access,” click it to disable hosting.

On your server:

• Ensure that “Host Multi-User Access” is enabled.

3. Check QuickBooks Services

Two services should always be running:

• QuickBooksDBXX (where XX is your version)

• QBCFMonitorService

To verify:

1. Press Windows + R, type services.msc, and hit Enter.

2. Find both services and ensure they are Running and set to Automatic.

3. If not, right-click > Start them and set Startup Type to Automatic.

4. Configure Firewall and Security Settings

Firewalls often block QuickBooks from accessing network files.

Steps:

1. Open Windows Firewall.

2. Go to Advanced Settings > Inbound Rules.

3. Add new rules for the following QuickBooks ports:

Version	Port Number
2022	8019, 56728, 55378-55382
2021	8019, 56727, 55373-55377

4. Allow QuickBooks and Database Server Manager through the firewall.

5. Ping the Server from Workstation

This ensures there are no DNS or IP conflicts.

Steps:

1. On the workstation, press Windows + R, type cmd, and hit Enter.

2. Type ping [ServerName] and press Enter.(Replace [ServerName] with your actual server name.)

3. If you receive a reply, the network is fine. If not, there’s a connectivity issue.

6. Rename the .ND and .TLG Files

These files help QuickBooks connect to the network. Corruption can lead to Error H202.

Steps:

1. Navigate to the company file folder.

2. Locate files with the same name as your company file but with extensions .ND and .TLG.

3. Right-click and select Rename.

4. Add .old to the end of the filename (e.g., companyfile.qbw.nd.old).

QuickBooks will recreate fresh files upon the next launch.
