You may sometimes encounter access issues when opening company files. One such issue is QuickBooks error H505, which prevents workstations from connecting to the server hosting the company file. When this error occurs, a specific message may appear on your screen: “Error Code: H505 This company file is on another computer, and QuickBooks needs some help connecting.” As this issue arises, you may notice the following reasons on your device:

  • QuickBooks may begin to crash repeatedly
  • The Windows operating system may become sluggish, unresponsive, or freeze intermittently

You may finish this up while trying to open a company file on a different system. Below are the reasons that we have mentioned:

  • Incorrect hosting setup in QB
  • Firewall settings in QB or Windows may block access to the company file
  • The Database Server Manager may be unable to scan the file or folder stored on the server
  • Incorrect DNS settings on the system may contribute to this error
  • QB may fail to detect the computer’s IP address, which results in connectivity issues
