Section 3: Troubleshooting QuickBooks Error Code H505

To resolve QuickBooks Error Code H505 effectively, follow these step-by-step troubleshooting methods:

  1. Verify Hosting Settings: Ensure that the hosting settings are configured correctly on the server and each workstation. Open QuickBooks on the server, go to “File,” and select “Utilities.” Check if “Host Multi-User Access” is enabled. If it is, disable it and re-enable it. Perform the same steps on the workstations.
  2. Check Firewall and Security Settings: Temporarily disable firewalls and security software on both the server and workstations to check if they are causing the issue. If disabling the firewall resolves the problem, add QuickBooks and its related processes as exceptions in the firewall settings.
  3. Examine DNS Settings: Ensure that the DNS settings on the server and workstations are accurate and in sync. You can use the “ipconfig” command in the Command Prompt to verify the DNS settings.
  4. Ping the Server: Use the “ping” command in the Command Prompt to check if the server is reachable from the workstations. If the server is not reachable, there might be network issues that need to be addressed.
  5. Repair or Recreate the .ND File: Close QuickBooks on all workstations and the server. Locate the .ND file for the company file on the server and rename it. After renaming, rescan the company file using the “Scan Folders” feature in QuickBooks Database Server Manager to create a new .ND file.
  6. Use QuickBooks File Doctor: Intuit’s QuickBooks File Doctor tool can automatically diagnose and fix common network-related issues that cause Error H505.
