Welcome to the QuickBooks Community, Havox. Let's perform other troubleshooting steps so your users can get rid of the H202 error in QuickBooks Desktop.
I suggest making sure QuickBooks services are running on your server computer. Beforehand, you and the users must ensure that QuickBooks has the recent release to keep the software up-to-date to have the latest features and product improvements.
Once done, follow the steps below:
- Open the Windows Start Menu on your server computer.
- Enter “Run” into the search and open Run.
- Enter “services.msc” into the Run window and press Enter.
- Find and double-click QuickBooksDBXX on the list. XX notes your version of QuickBooks.
- Choose Automatic for the Startup Type.
- Make sure the Service status is either Running or Started. If it’s neither, select Start.
- choose the Recovery tab.
- Select Restart the Service from each of these dropdown menus: First failure, Second failure, and Subsequent failures.
- Choose Apply and select OK to save the changes, then repeat these steps for QBCFMonitorService.
After that, launch QuickBooks on each workstation. Then, from the File menu, choose Switch to Multi-user Mode. If everything opens correctly, the problem has been resolved. If Error H202 persists, you can open this article and go to Solution 2 to fix the error: How to Fix Error H202 and H505.
Lastly, I'm adding this article if you need help fixing general problems when your company file won't open: Can't open your company file in QuickBooks Desktop.
