Common Causes of Error H505
Several factors can trigger QuickBooks Error H505. The most frequent causes include incorrect hosting configuration settings, where multiple workstations are configured to host the company file instead of just the server. Firewall and security software may also block QuickBooks from establishing necessary connections between computers on your network.
Network connectivity issues, damaged or corrupted DNS settings, and outdated QuickBooks software versions can also contribute to this error. Additionally, if QuickBooks services are not running properly on the server or workstation, the connection will fail, resulting in Error H505.
Step-by-Step Solutions to Fix Error H505
Solution 1: Verify Hosting Configuration
The first and most critical step is ensuring that only the server computer is hosting the company file. On each workstation, open QuickBooks and navigate to File menu, then Utilities. If you see "Stop Hosting Multi-User Access," click it to disable hosting on that workstation. This option should only remain enabled on the main server computer. Repeat this process on all workstations except the server.
Solution 2: Configure Windows Firewall
Proper firewall configuration is essential for QuickBooks multi-user functionality. You need to add exceptions for QuickBooks in your Windows Firewall settings. Open Windows Control Panel and navigate to System and Security, then Windows Defender Firewall. Click on "Allow an app or feature through Windows Defender Firewall" and ensure QuickBooks is checked for both Private and Public networks. You may also need to add specific ports that QuickBooks uses for communication.
Solution 3: Run QuickBooks File Doctor
Intuit provides a diagnostic tool called QuickBooks File Doctor specifically designed to resolve network and company file issues. Download the QuickBooks Tool Hub from the official Intuit website, install it, and open the Tool Hub. Select "Company File Issues" and then click on "Run QuickBooks File Doctor." Select your company file from the dropdown menu and choose "Check your file." The tool will automatically scan for and repair network connectivity issues.
Solution 4: Verify DNS Settings
Incorrect DNS settings can prevent QuickBooks from locating the server on your network. Open Command Prompt as an administrator and type "ipconfig /flushdns" to clear your DNS cache. Then restart your computer and try accessing the company file again. You should also verify that your network is using consistent DNS server addresses across all computers.
Solution 5: Use Server Name Instead of IP Address
When opening the company file, try using the server's computer name rather than its IP address. Open QuickBooks on the workstation, go to File > Open or Restore Company, and browse to the network location. Instead of typing the IP address, use the format: \SERVERNAME\SharedFolder\CompanyFile.qbw. This can resolve issues related to dynamic IP addresses that may change over time.
Solution 6: Restart QuickBooks Services
QuickBooks relies on several background services to function in multi-user mode. On the server computer, press Windows + R, type "services.msc" and press Enter. Look for QuickBooksDBXX (where XX represents your version number) and restart this service. Also check for QBCFMonitorService and restart it as well. Ensure both services are set to start automatically.
Solution 7: Update QuickBooks to Latest Version
Running outdated software can cause compatibility issues leading to Error H505. Open QuickBooks and go to Help > Update QuickBooks Desktop. Click "Update Now" and select "Get Updates." After downloading updates, close and reopen QuickBooks to install them. Restart your computer after the installation completes.

Preventing Future H505 Errors
Prevention is always better than troubleshooting. Maintain your QuickBooks software with regular updates and ensure all workstations are running the same version. Establish clear protocols for hosting configuration, ensuring only the designated server hosts company files. Regular network maintenance, including router and switch updates, helps maintain stable connections.
Create a documented IT policy for your QuickBooks environment, including firewall configurations, network topology, and user permissions. Regular backups of your company files protect against data loss during troubleshooting. Schedule periodic reviews of your multi-user setup to catch potential issues before they disrupt operations.
