Step-by-Step Solutions to Resolve QuickBooks Error H202

1. Verify Hosting Settings on All Workstations

Misconfigured hosting settings often cause error H202.

• Open QuickBooks on each workstation.

The QuickBooks File Doctor Tool can automatically diagnose and repair network issues.

• Download and install the QuickBooks Tool Hub from the Intuit website.

3. Configure Firewall and Security Settings

Ensure your firewall or antivirus software isn’t blocking QuickBooks.

• Enable inbound and outbound rules for QuickBooks ports (e.g., 8019, 56728, 55378-55382).

4. Repair the Network Data (.ND) File

A damaged .ND file can disrupt communication between the server and workstations.

• Navigate to the folder where your company file is stored.
• Look for the .ND file associated with your company file.
• Rename the file (e.g., CompanyName.qbw.nd to CompanyName.qbw.nd.old).
• Restart QuickBooks and try accessing the file.

5. Test Network Connectivity

Use the Ping command to verify the connection between the workstation and server:

• Press Windows + R, type cmd, and hit Enter.
• Type ping [ServerName] and press Enter.
• If you receive a timeout response, the server isn’t reachable. Check your network settings.

6. Restart the QuickBooks Database Server Manager

The Database Server Manager ensures workstations can access the company file.

• Open QuickBooks Tool Hub and select Network Issues.
• Launch the Database Server Manager and scan your company file folder.
• Restart the Database Server Manager and try accessing QuickBooks in multi-user mode.

7. Modify the Windows Hosts File

Incorrect or missing DNS entries can trigger error H202.
