The QB service account is local admin on the server. But if the company is first opened on a client PC, the users cannot switch it to multi-user mode, but gets the H202 error.
The strange thing is that if I open the same company from the "server" first, switch it to multi-user mode and then go to a client PC, they can access the company in multi-user mode fine. These companies were working fine in multi-user mode up to a few days ago. Since a few days ago I'm getting Error H202 when users try to switch companies to multi-user mode. The system was fine up to a few days ago, having been running for almost 2+ years now on this. I am having issues of this kind on an existing installation running QB 2016 Premier Accountant version.
I want to ensure that this is taken care of for you, so please feel free to let me know how it goes. That's it! For more detailed steps, I'm including a helpful article that you can check. Try opening QuickBooks in Multi-User mode on your workstation(s).Click Start Scan, which will repair the firewall permissions to allow QuickBooks to communicate over your network and resolve your error.If no folder locations are shown, click Browse and browse to the folder where you store your company file(s).Click on QuickBooks Database Server Manager.At your server computer (computer hosting your company file/s), open the start menu then type database.
To get this be fix, use the QuickBase Database Server Manager. I'd be glad to lend a hand in fixing error H202.
