What is QuickBooks Error H505?

QuickBooks Error H505 occurs when the software is unable to access a company file stored on a server. In a multi-user environment, QuickBooks requires a proper network configuration to allow multiple users to access the same company file. Error H505 usually indicates that the configuration is incorrect, such as issues with the network or the hosting settings. This can happen when QuickBooks cannot communicate with the server properly, often due to firewall, DNS, or hosting configuration issues.

Some common causes of QuickBooks Error H505 include:

  • Incorrect Hosting Configuration: QuickBooks Hosting is essential in multi-user environments, and incorrect configuration can prevent proper communication between the server and client systems.
  • Firewall or Antivirus Interference: Firewalls or antivirus software blocking QuickBooks connections to the server can cause Error H505.
  • Damaged Network Data Files: Corrupt or missing files that manage network data can disrupt communication and cause this error.
  • Wrong DNS Settings: Incorrect DNS settings or network setup can cause issues in connecting to the QuickBooks server.

Steps to Fix QuickBooks Error H505

1. Check and Configure Hosting Settings

One of the most common reasons for Error H505 is incorrect hosting configuration. QuickBooks requires that the correct hosting settings be configured for multi-user access. To resolve the issue, follow these steps:

  • Go to the File menu in QuickBooks and select Utilities.
  • Click on Host Multi-User Setup.
  • If the Stop Hosting Multi-User Mode option is available, select it and restart QuickBooks.
  • After restarting, go back to Host Multi-User Setup and choose Start Hosting Multi-User Mode.

This ensures the server is correctly set up for multi-user access and can resolve the H505 error.

2. Check Firewall and Antivirus Settings

Sometimes, firewalls or antivirus programs block QuickBooks from connecting to the server. To fix this:

  • Disable your firewall or antivirus temporarily and check if the error is resolved.
  • If disabling the firewall or antivirus fixes the issue, add exceptions for QuickBooks in your firewall and antivirus software.
  • You can also check QuickBooks’ support site for a list of specific ports and configurations needed for QuickBooks to communicate with the server without interference.

3. Verify the DNS Configuration

QuickBooks Error H505 can also occur if the DNS configuration is incorrect. To check DNS settings:

  • Open the Control Panel on your server.
  • Select Network and Sharing Center and then Change Adapter Settings.
  • Right-click on your network connection and select Properties.
  • Double-click on Internet Protocol Version 4 (TCP/IPv4) and verify that the DNS server addresses are correct. Ensure that the server is using the correct DNS settings to connect to the QuickBooks server.

4. Repair Network Data Files

Corrupt or damaged network data files can cause connectivity issues between QuickBooks and the server. You can repair the network data files by:

  • Closing QuickBooks on all computers.
  • Navigating to the QuickBooks folder on the server.
  • Running the QBNetworkTool to identify and repair network connectivity issues.

Running the tool will help identify any network data file corruption and resolve it.
