Detailed Resolution Steps for QuickBooks Error H202

When you encounter QuickBooks Error H202, it indicates communication problems within your network setup that prevent users from accessing the company file in a multi-user environment. Here’s a deeper dive into the steps to resolve this issue:

Step 1: Test Network Connectivity

• Ping Test: From each workstation, use the command prompt to ping the server:
  1. Open Command Prompt on each workstation.
  2. Type ping [Server-Name] and press Enter (replace [Server-Name] with the actual name of your server).
  3. If the response is timed out or lost, it indicates network issues that need further investigation.

Step 2: Use QuickBooks File Doctor

• Run File Doctor:
  1. Download and install QuickBooks Tool Hub from the official Intuit website.
  2. Open QuickBooks Tool Hub and go to the “Network Issues” tab.
  3. Click on “QuickBooks File Doctor” and run the tool.
  4. Please select your company file from the drop-down or browse to locate it manually.
  5. Choose the “Check your network” option and continue, then enter your Admin password if prompted.
  6. Let the tool diagnose and fix the network errors it finds.

Step 3: Configure Hosting Settings

• Single Machine Hosting:
  1. On each workstation (not the server), open QuickBooks and go to “File” > “Utilities.”
  2. If you see the “Host Multi-User Access” option, do not select it. This means this computer is not hosting the company file.
  3. If you see “Stop Hosting Multi-User Access,” select it to turn off hosting.
  4. Repeat this on all workstations except the server.

Step 4: Adjust Firewall and Antivirus Settings

• Configure Firewall:
  1. On the server, open the Windows Control Panel and go to “System and Security” > “Windows Defender Firewall.”
  2. Click on “Advanced settings” and then “Inbound Rules“.
  3. Click “New Rule” and select “Port“. Ensure TCP is selected and enter the specific ports needed for your QuickBooks year version (you can find this information on the QuickBooks site).
  4. Name the rule (e.g., “QBPorts(year)“) and save it.
• Antivirus Exceptions:
  1. Add exceptions for QuickBooks executable files (like QBW32.exe, QBDBMgrN.exe) in your antivirus software to prevent them from being blocked.

Step 5: Restart Database Server Manager

• Rescan Company Files:
  1. On the server, open QuickBooks Database Server Manager.
  2. If your company file folder isn’t listed, click “Add Folder” to locate and add it.
  3. Click “Scan” to reconfigure the QuickBooks File Hosting and firewall permissions automatically.

Step 6: Verify and Restart QuickBooks Services

• Service Verification:
  1. On the server, open the Run dialog by pressing Windows + R.
  2. Type services. msc and press Enter.
  3. Look for QuickBooksDBXX and QBCFMonitorService in the list.
  4. Ensure both services are set to “Automatic” and their status is “Running.” Right-click and choose “Restart” if necessary.
