QuickBooks Error H303: Problem with multi-user hosting setup…

If you see Error H101, H303, or H505, one or more of your workstations is set to be the server for QuickBooks. Your server (the computer that hosts your company files) should be the only computer set to host multi-user mode.

The Host Multi-User Access option should be turned off on your workstations. These are the computers on your network that don’t host your company files. Your server computer should be the only one hosting.

  Note: You can do these steps before opening a company file.
  1. Open QuickBooks on any workstations where you see H101, H303, or H505.
  2. Don’t open your company file. Instead, select the File menu and hover over Utilities.
  3. If you see the Host Multi-User Access option, don’t select it. Move on to the next workstation. This one isn’t causing the problem.
  4. If Stop Hosting Multi-User Access is an option, select it.

  1. Repeat these steps on all workstations where you see Error H101, H303, or H505.

After you check your workstations, move on to your server computer. This is the computer that normally hosts your company files.

  1. Open QuickBooks on your server computer.
  2. Open the File menu and hover over Utilities.
  3. If Host Multi-User Access is an option, select it. If Stop Hosting Multi-User Access is an option, don’t select it.
