How to Prevent QuickBooks

Error code H505 indicates that QuickBooks Desktop cannot access company files on another computer. Usually this occurs because the host server has incorrect hosting settings.

Problems related to internet connectivity may include network issues or firewalls blocking connections; misconfigured hosting services are another likely culprit.


QuickBooks Error H505 usually occurs when trying to use a company file located on another computer. This could be caused by either network connectivity issues or firewall blocks which prevent both computers from communicating effectively with each other.

Error 306 may also arise if you try to access your company file on a system without full QuickBooks setup, in which case it’s essential that only accessing company files on their original host server should be attempted.

Host Multi-User Access

First, check that no workstation has the “Host Multi-User Access” option enabled; if so, disable it immediately.

Next, ensure that only your server company file hosts multi-user mode – otherwise QuickBooks won’t connect to other workstations within your network when their versions don’t have it enabled.

Assuming you know which workstations have this error message, to test that this is indeed the issue, open QuickBooks on each workstation where this error occurs and select File, Multi-user Mode from within QuickBooks. Also make sure that server computers act as workstations are checked!

If this solution does not resolve the error, try the QuickBooks Database Server Manager to scan your company files and correct any firewall permission issues that prevent access by software programs.

Once the fix has completed, you should be able to open and use your company file without encountering any errors. However, if any persist, reboot your computer and try again; otherwise contact an IT specialist for assistance.
