Important: Do the following steps on your server computer (the machine that physically hosts your QuickBooks company file(s). You will also need to make sure you sign in to the server as the administrator user (or user with administrator rights) to be able to run the File Doctor.

BEFORE YOU BEGIN: Ensure QuickBooks is Installed on your Server Computer

Ensure QuickBooks is installed on your server before you begin.  It can be installed with a license (full QuickBooks Desktop) or without a license (database manager hosting only).  If QuickBooks is not installed on your server, you will not be able to use multi-user mode.

On each workstation (not the server or hosting computer), go to QuickBooks File menu > Utilities. Note: This can be done even without opening a specific company file.
  • If you see Host Multi-User Access on the list, this computer is not hosting the company file and you can go to the next computer.
  • If you see Stop Hosting Multi-User Access, select that option to disable hosting on your workstation, which will fix the H505 errors.
  • Ensure all workstation(s) in your office look like this under the File -> Utilities menu:
