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

  • 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).

  • The .ND file is damaged or incorrect.
  • QuickBooks can't obtain the IP address of the system or server hosting the company file.
