Important: Devices like Network Attached Storage (NAS) don’t support the Database Server Manager. 

Solution 1: Run the QuickBooks Database Server Manager on your server

Step 1: Download and install the QuickBooks Tools Hub on your server

The QuickBooks Tool Hub helps fix common errors. For the best experience, we recommend using Tool Hub on Windows 10, 64-bit.

  1. Close QuickBooks.
  2. We recommend you download the most recent version ( of the QuickBooks Tool Hub. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). Note: If you’ve already installed Tool Hub before, you can find out which version you have. Select the Home tab.  The version will be displayed on the bottom right or you can select About to view the version.
  3. Open the file you downloaded (QuickBooksToolHub.exe).
  4. Follow the on-screen steps to install and agree to the terms and conditions.
  5. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.

Note: If you can’t find the icon, do a search in Windows for QuickBooks Tool Hub and select the program.


Step 2: From the Tools Hub, run the QuickBooks Database Server Manager on your server

Your server computer is the one that stores your QuickBooks company file(s). Your other computers connected to your network are your workstations.

  1. From the QuickBooks Tools Hub, select Network Issues.
  2. Select QuickBooks Database Server Manager. If QuickBooks isn’t installed on your server, you’ll be prompted to install it.
  3. Inside the QuickBooks Database Server Manager, select Start Scan if your company file folder(s) are displayed. If they aren’t, Browse to the location of your company file and then select Start Scan.
  4. The QuickBooks Database Server Manager will repair your firewall permissions automatically.  When the scan finishes, select Close.
  5. Open QuickBooks on each workstation where you see Error H202. Select File and Switch to Multi-user Mode. If you use your server computer as a workstation, be sure to check it too.

If your workstations can go into multi-user mode without any issues, everything is fixed.

Fix Error H101, H303, and H505

This shows the error message you get in QuickBooks for error H505

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 connected to 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.This image shows the open File menu with utilities selected. You can see the Stop Hosting Multi-User Access option.
  5. 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.
