Troubleshooting Method 3 – Verify Correct Hosting Settings On The Server

The main reason for the error H202 is when the server is not correctly set to host the company file. Let’s quickly verify the correct hosting settings to address this problem:

• Go to your Server Computer where the company file is saved.
• On this computer, open QuickBooks Desktop.
• Move to the File tab, and choose Utilities.
• Here, if you see the Host Multi-User Access option, select it to enable. But, if you see the Stop Hosting Multi-User Access, it indicates that the hosting is already enabled. Leave it enabled only.
• Make sure that each workstation shows the Host Multi-User Access option and not the “stop hosting” option in the Utilities menu.

Always ensure that the server should host the file to prevent multi-user problems such as error h202.

Troubleshooting Method 4 – Ensure Correct QuickBooks Services On The Server

Incorrect QuickBooks services on the server can be also a reason for facing the QuickBooks error code H202. Follow the instructions below to verify these QuickBooks services on the server:

• Go to your Server Computer and press the Windows button.

• After this, test the multi-user mode by opening QuickBooks on each workstation. Click File and select Switch to Multi-User mode.

Troubleshooting Method 5 – Fix Name Resolution Of Windows Hosts File

If the Windows hosts file has incorrect or outdated IP to hostname mappings, the workstation fails to connect with the server’s network address, which further blocks the connection to the QuickBooks database service leading to QuickBooks multi user error code H202. Here’s how you can fix it:

• Begin by first getting the Server’s details. For this, open Command Prompt on the Server computer.
• Enter ipconfig /all in the window and note the Host name (e.g. QBServer) and the IPv4 Address (192.166.1.70).
• Next, login into the workstation using admin credentials and move to the C:\Windows\System32\Drivers\etc\.
• Now, look for the hosts file (no extension). Once you find these files, right-click them, and select Run as Administrator.
• At the bottom of the host file, you need to add a line with the server’s IP and name.
• Make sure you press Tab key between the IP and the server name.
• After this, save the changes and repeat the above steps on each workstation that needs access to the QuickBooks Desktop.
• Finally, test multi-user mode. If you still find the QuickBooks H202 error multi-user problem, let’s try another method.

• QuickBooks Desktop 2019: 8019, XXXXX
• QuickBooks Desktop 2018: 8019, 56728, 55378–55382
• QuickBooks Desktop 2017: 8019, 56727, 55373–55377

Note – XXXXX represents the dynamic port number, which is assigned to your QuickBooks version. This number is available in the Port Monitor Tab of the QuickBooks Database Server Manager on the server.

8. The next step is to add exceptions for QuickBooks executable files. It will help you fix error code H202 in QuickBooks Desktop by preventing security tools from blocking critical accounting processes, network communication, and multi-user data sharing.

• Now, check the response. If you receive messages, such as any replies, it means that the workstation can communicate with the server.

Step 4 – Check For Connection Problems

• If you see Request timed out or Ping request could not find host, there may be a network, name-resolution, or firewall issue.
• If multiple computers use the same company file, run the same test on each workstation.

Note – If pinging the server name fails, use ipconfig on the server to find its IPv4 address, then run ping [IP address] from the workstation.
