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)
  • 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)
  • 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)
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.

How to fix it

Before you attempt to fix any of these issues, you need to know which computer is the host computer.  This will depend on the type of set up you have.
