Top Solutions to Fix QuickBooks Error H202

Here’s how to troubleshoot and fix the issue step-by-step.

1. Use the QuickBooks Database Server Manager

QuickBooks Database Server Manager allows workstations to communicate with the server hosting the company file.

Steps:

1. Download and install QuickBooks Tool Hub (if you haven’t already).
2. Open Tool Hub and go to Network Issues tab.
3. Click QuickBooks Database Server Manager.
4. Scan the folder where the company file is stored.
5. Once the scan is complete, restart QuickBooks in multi-user mode.

2. Check and Configure Hosting Settings

Make sure only the server computer is set to host multi-user access.

On all workstations:

• Open QuickBooks and go to File > Utilities.
• If you see Host Multi-User Access, do nothing.
• If you see Stop Hosting Multi-User Access, click it to disable hosting.

3. Create a New Windows Firewall Rule

Your firewall may be blocking the connection to the server.

Steps:

1. Open Control Panel > Windows Defender Firewall > Advanced Settings.
2. Click on Inbound Rules > New Rule.
3. Choose Port, then click Next.
4. Add the following TCP ports:
   • QuickBooks 2021: 8019, 56728, 55378-55382
   • (Adjust based on your QuickBooks version)
5. Allow the connection and complete the setup.

Repeat the steps for Outbound Rules.

4. Edit the Hosts File (Advanced Users)

Manually adding the server IP and name to the Windows hosts file can help resolve network communication problems.

Steps:

• Open Notepad as an Administrator.
• Navigate to:
  C:\Windows\System32\Drivers\Etc\hosts
• Add the server’s IP address and name at the bottom.
• Save the file and restart QuickBooks.

5. Ping the Server from Your Workstation

To confirm if the connection is active:

1. Press Windows + R, type cmd, and press Enter.
2. Type: ping [ServerName]
3. If you receive replies, the connection is active. If not, there’s a network issue that needs fixing.

Preventing QuickBooks Error H202 in the Future

Prevention is always better than troubleshooting. Here are some proactive tips:

• Regularly update QuickBooks and Windows.
• Make sure your firewall and antivirus are configured correctly.
• Use a reliable local network or server environment.
• Avoid unstable Wi-Fi for server hosting.
• Set up QuickBooks Database Server Manager correctly.
