Common Causes of QuickBooks Error H202

  1. Incorrect Hosting Configuration: This happens when the hosting settings on the server or workstation are misconfigured.

  3. Damaged Network Data (.ND) Files: The network data files (.ND) could be damaged or corrupted, leading to connectivity issues.

  4. Incorrect DNS Settings: If the DNS settings on the server or workstation are not configured properly, it can prevent QuickBooks from resolving the host computer.

Step-by-Step Guide to Fix QuickBooks Multi User Error H202

Here’s how you can troubleshoot and resolve QuickBooks Multi User Error H202 effectively:

Step 1: Verify Network Connectivity

  • Check Network Connection: Ensure that all computers (server and workstations) are connected to the same network.

  • Ping the Server: Use the Command Prompt on each workstation to ping the server where the company file is located. This helps verify connectivity.

Step 2: Verify Hosting Settings

  • Set Hosting to Local Files Only on Workstations: Open QuickBooks on each workstation, go to File > Utilities > Stop Hosting Multi-User Access. Repeat this step on all workstations except the server.

  • Set Hosting to Multi-User Mode on the Server: Open QuickBooks on the server, go to File > Utilities > Host Multi-User Access.

Step 3: Check Firewall and Security Software Settings

  • Configure Firewall Settings: Add exceptions to the firewall for QuickBooks to allow incoming and outgoing communication on ports:

    • QuickBooks Desktop 2018: Ports 8019, 56728, 55378-55382
    • QuickBooks Desktop 2019: Ports 8019, 56729, 55383-55387

  • Configure Antivirus/Security Software: Ensure that your antivirus or security software is not blocking QuickBooks processes or ports.

Step 4: Create and Verify Network Data (.ND) Files

  • Locate .ND Files: On the computer where the company file is stored (usually the server), navigate to the folder where the company file is located and find the corresponding .ND file.

  • Delete and Recreate .ND Files: Right-click on the .ND file and select Delete. Open QuickBooks on the server, go to File > Open or Restore Company > Open a company file, and browse to the company file. QuickBooks will recreate the .ND file.

  • Set DNS to Automatic (Workstations): Go to Control Panel > Network and Sharing Center > Change adapter settings > Right-click on your network adapter > Properties > Internet Protocol Version 4 (TCP/IPv4) > Ensure both Obtain an IP address automatically and Obtain DNS server address automatically are selected.

  • Flush DNS Cache: Open Command Prompt as Administrator and type: ipconfig /flushdns

Step 6: Test Connectivity

  • Open QuickBooks: Open QuickBooks on each workstation and try to access the company file in multi-user mode.
