Accessing your Quickbooks files on the network requires Quickbooks Hosting to be turned on.

Turn On Hosting

Hosting QuickBooks company data files in multi-user mode

In QuickBooks, hosting can be described as the situation where the computer that is storing a company file allows the other computer(s) to access the same file over a shared network.

QuickBooks Desktop is used to manage the company file,

  • QuickBooksDB28 used by QuickBooks Desktop 2018.
  • QuickBooksDB27 used by QuickBooks Desktop 2017.
  • QBDB26 used by QuickBooks Desktop 2016.

You can find this service in User Account and under Users on your computer. However, keep in mind that the service corresponds to your version of QuickBooks Desktop.

How do you access your company files?

QuickBooks Desktop edition has three conditions to access the company files:

(a) Windows File permissions: User who is logged in must have permissions to full control, which get the permissions to view, modify, and open the file.

(b) Database Server mode: It can be used to open the company file.

(c) QuickBooks User login: Each user has QuickBooks user login ID and password.

Finally, after meeting all three conditions, you can access your company file.

Hosting Modes

Each version of QuickBooks Desktop and for each mode is set on hosting mode. When you use multiple versions of QuickBooks (2015 or later), they are used concurrently, the settings of each version are independent in the hosting mode.

Here, we use three types of hosting modes. These are Not hosting (it is also called Hosting Off), Hosting Local Files only, and Hosting Local & Remote files.

  1. Not Hosting mode:

  • QuickBooks Database Manager runs in the normal process when the windows User running QuickBooks.
  • It does not support multi-user mode. It cannot use shared memory to communicate with QuickBooks. In this mode, only the QuickBooks user can use the database server to access a file on the local computer.
  1. Hosting Local Files only mode:

QuickBooks Database Server Manager can run only as a Windows service, that is, QuickBooks DBXX. (where XX determines the numbers from 17 to 28 by the version of QuickBooks and describes under the “Hosting defined” above) and it is also for Windows user QBDataServiceUserXX (the XX being the same 2-digit number from 17 to 28 that the Windows service uses).

  • The QuickBooksDBXX service is always running while the computer is on.
  • It supports multi-user mode while using TCP/IP to communicate with QuickBooks. QuickBooks users can access company files using a database server running in Hosting Local Files only mode.
  • Local Files only mode can host those files that are located on that computer where a computer is hosting.
  1. Hosting Local & remove files mode:

  • When you are currently logged on as a Windows user, then QuickBooks Database Manager runs as a normal process. When the user logs in, then this process gets started and when the user logs out, this process also terminates.
  • It supports multi-user mode while using TCP/IP to communicate with QuickBooks. The QuickBooks users on remote computers can access company files on this computer using a database server.
  • Host files are stored in local computer mode and that file is found in remote computers and opened on the local computer.

How QuickBooks Desktop Determines Which Database Server To Communicate With?

  1. QuickBooks Desktop looks only for the .ND file. This file is a small text file with the same name as the company file and with a .ND file extension. This file is in the same directory as the company file, where there is a use of .QBW extension. It also contains the information needed to contact the server, such as the IP address and network port.
  2. Where there is a use of .QBW file, it is determined in QuickBooks Desktop.
  3. When QuickBooks Desktop finds the .ND file, it detects the company file is in use, then QuickBooks tries to communicate with the server:
  • If the result comes successfully, then QuickBooks opens the company file.
  • If the result comes unsuccessfully, then the error message that describes the steps needed to resolve the issue appears.
