How to Fix Quickbooks Errors H202, H101

October 26th, 2021

Quickbook errors H202 and H505 occur when you try to switch to multi-user mode, but something is interfering with the connection to the server.

How to Resolve Error H202

Error code H202 warns you that “This company file is on another computer, and QuickBooks needs some help connecting.”


The first step in fixing Error H202 depends on how you host your company files.

If you host on your own computer, you should have followed the steps to install QuickBooks Database Server Manager on your server for each QuickBooks version you use.

You can either set up the database server manager with:

  • The full program option, where you install the full version of QuickBooks Desktop and Database Server Manager on your computer.
  • The server only option, in which you only install Database Server manager.

You may also host with Windows Server 2012 Essentials R2 to host your network or with another hosting solution. In this case, don’t follow the steps below


Now follow these steps to troubleshoot:


  1. First Try to Resolve the Issue by Running the QuickBooks Database Server Manager
  • Close QuickBooks
  • Download the most recent version of the QuickBooks Tool Hub.
  • Save the file somewhere you can find it easily, then open the file.
  • Follow the instructions to install, then open the tool hub
  • Now, run the QuickBooks Database Server Manager on your server
  • From the tools hub, click Network Issues.
  • Inside the Database Server Manager, click Start Scan if you see your company’s files, otherwise choose Browse to locate them, then click Start Scan.
  • The Database Server Manager will repair firewall permission automatically. When the scan is complete, click
  • Now, open QuickBooks on each workstation that had error code 202. Select File, then Switch to Multi-User Mode. If you use the server as a workstation, check it also.

If you still see the error code, move on to the next step.


  1. Check the services on your server.
  • Before you begin, if you use the Full Program option, first turn on multi-user hosting. In the File menu, select Utilities, If Host Multi-User Access appears as an option, choose it.
  • Now, make sure QuickBooks services are running on your server:
  • Open the Windows Start Menu, type Run in the search bar and open Run.
  • Type msc in the Run window and click Enter.
  • Double-click Note: .XX stands for your version of QuickBooks.
  • Click Automatic for the Startup Type.
  • Service status should be Running or Started – if not, click Start

  • Click Apply, then select
  • Repeat the steps for the QBCFMonitorService.


If you still get Error H202, try the third step.


  1. Add services to your Windows Admin Group
  • Make sure you’ve given QuickBooksDBXX and QBCFMonitorService administrative permissions on your server. See this QuickBooksHelp article for more information.
  • Now, Open QuickBooks on your server and workstations.

If you still get error H202, try step 4.


  1. Configure firewall settings on your server.


If you still see error H202, move on to step 5.

  1. Check your connection to the server from a workstation receiving the error.
  • Turn on Network Discovery on your computer and workstations with the error.
  • Open the Windows Start menu on your server and the workstations.
  • Enter Network into search and open Network and Sharing Center.
  • Select Change advanced sharing settings.
  • Ensure Turn on network discovery is selected in the Network Discovery and File and printer sharing.

Now find your server name:

  • Open the Windows Start menu on the server
  • Type Run into search and open Run.
  • Type CMD into the Run window and click Enter.
  • Type ipconfig/all into the CMC window and click Enter.
  • Find the host name in the Windows IP Configuration section. The server name is on the right.

Write the host name or copy it to a doc so you can access it easily.

At your workstation, open the Windows Start menu.

Type Run into search and open Run.

Type CMD into the Run window and click Enter.

Type ping [your server name] and click Enter.

If there is packet loss or a very slow reply, contact an IT professional for help, otherwise, your server -workstation connection is fine, and you can move on to the next step.


  1. Add your server to your Windows hosts file.

Contact QuickBooks for instructions.

If this step doesn’t resolve error H202, contact Virtual Systems for additional guidance.



How to Resolve Errors H101, H303, H505

When these error codes appear, one or more of your workstations are set as the server for QuickBooks. Only your server should be the computer that hosts QuickBooks, and it should be set to multi-user mode.

Host Multi-User Access should be turned off on workstations.

Open QuickBooks on any workstation where you see error code H101, H303, H505.

Select the File menu and hover over Utilities.

If you see Host Multi-User Access, don’t select it. Repeat for each workstation until you locate the one creating the issue. When you find a workstation where you see Stop Hosting Multi-User Access select it.

  • Open the File menu and hover over
