A multi-user mode configuration failure is usually indicated when workstations are unable to connect to a company file stored on a server. The QuickBooks Error H202 is a typical connectivity issue that can be caused by firewall limitations, improper QuickBooks Database Server Manager configuration, or insufficient network rights. Collaborative work is stopped, and the host computer needs to be attended to right away.
The server computer is where the resolution process starts. Make that the folder holding your company file is correctly added to the QuickBooks Database Server Manager, which is installed and operating. Next, set up the server and workstations' firewalls to make exceptions for the QuickBooks executables (qbw32.exe and qbdbmgrn.exe). Lastly, use the Database Manager's "Scan Folders" and "Update Lists" features to confirm that every user has complete control over the shared folder. Version conflicts that cause this problem can also be avoided by regularly updating QuickBooks on all computers.
