How can you access the company file

Before accessing the company file. Remember these conditions:

  • Windows File Permissions: The login user has full control over the system, including permission to look at the data, open it, and modify data.
  • Database server mode: Database Server Mode can open the company file successfully.
  • QuickBooks Online User login: Before accessing the system every user must have the QuickBooks login username and password.

Hosting modes

Hosting mode is available for every version of QuickBooks Desktop and for each system. It is not installed for QuickBooks installation or company files. Hosting mode settings for each version of  QuickBooks 2017 and later versions independently.  

Three types of hosting modes: 1. Not hosting (also known as hosting Off), 2. Hosting local files only, and 3. Hosting local and remote files.

1. Not hosting mode:

  • QuickBooks Database Manager runs always in a normal process: As a Windows User running QuickBooks. 
  • Not hosting mode does not support multi-user mode. In this mode, memory is distributed between the users to communicate with QuickBooks. The important thing to remember is in this mode, only local system QuickBooks users can use a database server to access a file.

2. Hosting local files only mode:

  • In Hosting local files only mode QuickBooks Database Server Manager runs on a Windows service named QuickBooksDBXX (where XX is a number from 27 to 30 defined by the version of QuickBooks, as specified under “Hosting defined,” above) and as the Windows user QBDataServiceUserXX (with XX being the same 2-digit number from 27 to 30 that the Windows service uses).
  • As long as the system is on, QuickBooksDBXX service always running.
  • In hosting local files Multi-user mode is supported and using TCP/IP to reach out with QuickBooks. QuickBooks users who are on the remote systems can access company files using access company files with a database server running in Hosting Local Files only mode. 
  • A system in Hosting Local Files Only mode can host only those files that are located on that system.

3. Hosting Local and remote files

  • QuickBooks Database Manager works as a normal process, the user is currently logged on as a Windows user.  The process goes on until the user logs out of the system.
  • In Hosting Local & Remote system can support multi-user mode, using TCP/IP to data transfer with QuickBooks. QuickBooks users on the remote system can access company files on the local system using the database server.
  • In this mode, the local system can host files stored in it and also stored on the remote system and open on the local system.

How does QuickBooks Desktop decide which database server to interact with?

  1. QuickBooks Desktop search for .nd file. The .nd file has the same name as the company file but with a different QuickBooks file extension (.nd file extension). And place it in the same directory whose extension is .qbw. The directory also stores the information to reach the server, like IP address and port. 
  2. QuickBooks Desktop check .qbw file is in use or not.
  3. After searching .nd file and verifying that the company file is in use, QuickBooks tries to reach out to the server: 
  • Then communicating QuickBooks opens the company file.
  • But if it is not successful, and it shows errors like H101, H202, H303, or H505 while opening the company.

A folder including the file is not writable or not shared

The company file folder must be shared with every other user. And Set up folder and Windows access permissions to share company files to share them, other users.
