Error H101, H202, H303, or H505: when opening your company file

When you open a company file in multi-user mode, you see an error:

  • You're trying to work with a company file located on another computer, and this copy of QuickBooks can't reach the server on that computer (H202).
  • It appears that the QuickBooks software on computer [server name] is set up to allow shared connections to the company file, but the QuickBooks software on your computer is unable to communicate with it (H202).
  • You're trying to work with a company file located on another computer, and that computer needs additional installation and setup. (H101, H303, and H505).

Note: Intuit does not support firewall or anti-virus programs. You may need to consult the program provider for assistance with installing and setting up your program.

Why this is happening

QuickBooks is trying to establish a connection to the company file and can't communicate with the server (computer hosting the QuickBooks files). Several issues can cause these errors:

  • Hosting configuration settings are incorrect.
  • The firewall is blocking incoming/outgoing communication to the company file.
  • The .ND file is damaged or incorrect.
  • QuickBooks can't obtain the IP address of the system or server hosting the company file.
  • Workstations are configured to open the file through the hosts Full Qualified Domain Name (ex. computername.domain.com) or DNS settings are incorrect.
  • The QuickBooksDBXX or QBCFMonitor services are not started.
