QuickBooks Error Code H505 - Troubleshooting Steps and Solutions

When QuickBooks Desktop is unable to connect to the company file on a different computer or server, error code H505 is generated. The measures you can take to resolve QuickBooks Error Code H505 are listed below:

Make sure that only the computer hosting the company file has hosting enabled by checking the hosting configuration settings. To do this, launch QuickBooks on the server computer, choose Utilities from the File menu. If you see the option to "Stop Hosting Multi-User Access," hosting is activated on that machine. By choosing "Host Multi-User Access" from the same Utilities menu, you can turn off hosting on all other workstations.


To make sure the server and workstations can resolve the right IP address, review and update the DNS settings. You can verify the DNS settings in each computer's network adapter settings or ask your network administrator for help.

Restarting the QuickBooks Database Server Manager requires restarting the server manager on the machine holding the company file. The service connected to QuickBooks Database Server Manager can be restarted by logging into the Windows Services console.

I advise contacting QuickBooks support or looking for help from a knowledgeable IT specialist by calling at toll-free number +1(855)-955-1942 if you have tried these solutions and are still encountering QuickBooks Error Code H505.

Here are some things you can do to try to fix QuickBooks error code H505:

Check your firewall settings: Make sure that QuickBooks is not blocked by your firewall.

Check the server's network settings: Make sure that the server is properly configured and that it is accessible from your computer.

Repair the company file: If the company file is corrupt, you can try repairing it using the QuickBooks File Doctor.

Reinstall QuickBooks: If the company file is not corrupt and you are still getting the error, you can try reinstalling QuickBooks.
