So, you are able to access QuickBooks when you are in the single-user mode, but as soon as you move to multi-user mode the screen displays an error and you are no longer able to use QuickBooks as good as before. The error is read as QuickBooks Error H202, which arrives when switching to multi-user mode. The FastFix247 Experts are going to help you resolve this error without much hassle.

Why does Multi-user error occur on your QuickBooks?

There are several factors that affect the multi-user function of QuickBooks. A little bit of change in any of them could cause the error to surface and create issues. These factors are Hosting and Services Settings, Network Ports, Server, and Damaged Company File Location.

How to resolve QuickBooks Error H202?

We will follow a few simple options to resolve the issue correctly and in time. Please follow them one by one to find out which one works for you:

Hosting Services:

Only the Hosting Computer (server) should be hosting-enabled, not any other. We will verify this in the next steps:

  1. Go to each workstation one by one and open QuickBooks. Go to File and then
  2. If Host Multi-user Access is available on the list, then the computer does not host company files. Move to the next workstation.
  3. If Stop Hosting Multi-user Access is visible in the options, click it.
  4. Repeat the same for each workstation.

Configuring Firewall:

Go to each workstation and perform the steps given below:

  1. Go to Windows Firewall
    1. On your desktop, go to the Windows Logo and right-click it. Next, select the Control Panel.
    2. Go to the Search Bar, type Firewall and hit Enter.
  • Choose the Windows Firewall and then Advanced Settings.
  1. Go to the left and right-click Outbound Rules and then click New Rule.
  2. Click on Ports and then hit
  3. Choose TCP and then go to the specific local ports box and enter the following data in the ports:
    1. QuickBooks Desktop 2018: 8019, 56728, 55378-55382
    2. QuickBooks Desktop 2017: 8019, 56727, 55373-55377
  • QuickBooks Desktop 2016: 8019, 56726, 55368-55372
  1. Hit Next, and then select Allow the connection.
  2. Hit Next, and enter a name in the name field. Hit
  3. For Inbound Rules, repeat the actions 1-5.
  4. Launch QuickBooks in Multi-user mode once more.

Creating a new Folder for Company File:

  1. Go to the hosting computer, create a new folder, share it and setup Access Permissions for sharing of Company Files through your New Folder and Windows.
  2. Copy the .qbw file and paste it in the location.
  3. Try to launch your file in Multi-user mode once more.

    Checking UNC vs. Mapped Drive (file path troubleshooting):

    These steps involve knowing technical knowledge. Get in touch with the QuickBooks Technical Experts if you require any help before or during the process.

  1. Launch Run prompt by clicking Windows+R Keys.
  2. Type in the Ping and hit You will see the replies for all the packets without any being lost.
  3. If you are connecting to your company file on the server through the mapped drive, go to your workstation computer and bypass the mapped drive by browsing to the server shared folder via UNC.
  4. The UNC path you found in the title bar, use it to navigate to your company file.

You should be able to resolve the problem within a few simple solutions. If you need technical assistance, we suggest you to get in touch with our QuickBooks Experts.
