What is the QuickBooks error H202?

First thing first: QuickBooks comes with both one user mode and multi-user mode. With one user mode as the name indicates only one person on one company file can work.

How To Fix QuickBooks Error H202?

Before you start following the below-mentioned troubleshooting steps, you need to clear one. I mean, you need to make sure that you have purchased the QuickBooks with multi-user mode. Actually, the problem is that many QuickBooks users purchase the single user mode license and when they try to switch to multi-user mode which they are not entitled to, they get an obvious error like H202. So, avoid making such silly mistakes in the first place. If you have licensed to multi-user mode and are getting this error then follow these steps in the sequence I have laid out for you. 
Install QuickBooks Database Server Manager
Normally, in the absence of the QuickBooks database server manager, the computer keeps working as the host of your company file. If your computer due to any whatsoever reason is not able to host your company file then it is time to host your own network with the QuickBooks database server manager. Once you download the database server manager from QuickBooks then according to your requirement you can choose any option between the full program and server only option.

Now choose recovery and select restart the service from each of these drop-down menus: First failure, Second failure, and Subsequent failure.
Consider to Add Services To Your Windows Admin Group
If you have tried everything but found no solution then it is time to give QuickBooksDBXX and QBCFMonitorService admin permissions on your server computer. When you’re done, open QuickBooks on your server computer and workstations.
