In this comprehensive guide, we will explore QuickBooks Error H202 in detail, including its causes, symptoms, and step-by-step solutions to resolve it.

Understanding QuickBooks Error H202

Common Causes of QuickBooks Error H202

Step-by-Step Guide to Resolving QuickBooks Error H202

Resolving QuickBooks Error H202 involves several troubleshooting steps. Here’s a comprehensive guide:

1. Check Network Connectivity

Ensure that all computers are properly connected to the network:

• Ping the Server:
  • Open the Command Prompt on one of the workstations (client computer).
  • Type ping [servername] (replace [servername] with the name of your server) and press Enter.
  • If you receive a reply, it means the server is reachable. If not, there is a network connectivity issue that needs to be resolved.
• Check Network Configuration: Ensure that all computers are on the same network and properly configured.

2. Verify Hosting Configuration Settings

Ensure that the hosting settings are correctly configured:

• On the Server:
  • Open QuickBooks and go to File > Utilities.
  • Ensure that "Host Multi-User Access" is selected. If it says "Stop Hosting Multi-User Access," click on it to stop hosting, then go back and select "Host Multi-User Access."
• On the Workstations:
  • Open QuickBooks and go to File > Utilities.
  • Ensure that "Host Multi-User Access" is not selected. If it says "Stop Hosting Multi-User Access," do not select it.

3. Add Firewall Exceptions for QuickBooks

Configure your firewall to allow QuickBooks to communicate through the network:

• Open the Control Panel:
  • Go to System and Security > Windows Firewall.
  • Click on Advanced settings.
• Add New Rules:
  • Select Inbound Rules and click on New Rule.
  • Choose Program and click Next.
  • Select This program path and browse to the QuickBooks executable file (e.g., QBW32.EXE).
  • Click Next and select Allow the connection.
  • Click Next and ensure all profiles are checked, then click Next again.
  • Name the rule (e.g., "QuickBooks Inbound") and click Finish.
• Repeat for Outbound Rules:
  • Follow the same steps to add a new outbound rule.

4. Configure the Windows Hosts File

Add the server name and IP address to the Windows hosts file to resolve DNS issues:

• Locate the Hosts File:
  • Navigate to C:\Windows\System32\Drivers\Etc.
• Open and Edit the File:
  • Open the hosts file with Notepad.
  • Add the server's IP address and name at the bottom of the file (e.g., 192.168.1.100 [servername]).
  • Save and close the file.

5. Repair the Network Data (ND) File

The .ND file enables QuickBooks to access the company file in a network. Repairing this file can resolve the issue:

• Locate the .ND File:
  • Navigate to the folder where your company file is stored.
  • Look for the file with the same name as your company file but with an .ND extension (e.g., CompanyFileName.ND).
• Rename the File:
  • Right-click on the .ND file and select Rename.
  • Add .old to the end of the file name (e.g., CompanyFileName.ND.old).
• Rescan the Folder:
  • Open the QuickBooks Database Server Manager.
  • Click on Start Scan and browse to the folder containing your company file.
  • Click OK and let the scan complete.

6. Restart QuickBooks Database Server Manager

Ensure that the QuickBooks Database Server Manager is running:

• Open Services:
  • Press Win + R, type services.msc, and press Enter.
• Locate the Service:
  • Find QuickBooksDBXX (where XX is the version number) in the list of services.
• Restart the Service:
  • Right-click on the service and select Restart.
• Check Service Status:
