When the Hosting Mode is turned off

Here are the results of file doctor test that would help you eliminate network issues with QuickBooks. To access your QuickBooks files, turn on the Hosting.

Note: You can ignore this warning if you are working on a workstation computer.

Now turn on the hosting!

When you are hosting QuickBooks Company Data Files in multi-user mode:

QuickBooks Company Data File Hosting means that you allow other computers or workstations to access the file. This file is easily accessible to the host (main computer) as only this host contains the company data file.

The following services are used by QuickBooks Desktop to manage company file access:

You can also find this service in the Windows Control Panel. Now, you are required to look for the service that corresponds to the version of QuickBooks Desktop you are using.

Modes of Hosting:

You need to know that the hosting mode is set for the versions of QuickBooks Desktop as well as for other computers. But this hosting mode is not set for the company file. The hosting mode settings go independent when multiple versions of QuickBooks 2016 or later are used simultaneously. Usually, there are a total of three hosting modes:

Not Hosting Mode:

  • Just like the Windows user running QuickBooks, QuickBooks Database Server Manager also runs a normal process.
  • Multi-user mode is not supported by the Not Hosting Mode. To communicate with QuickBooks, shared memory is used by this hosting mode. Moreover, database server to access a file can be used only by the QuickBooks user who is running QuickBooks on the local computer.

Hosting Local Files only

  • A Windows service namely QuickBooks DBXX is run by QuickBooks Database Server (Here XX is a number from 17 to 32 that indicates the version of QuickBooks). And also as the Windows user QBDataServiceUserXX (where XX is a 2-digit number from 17 to 32).
  • The service QuickBooksDBXX runs until the computer is on.
  • To communicate with the QuickBooks software, multi-user mode is supported using TCP/IP. Note that QuickBooks users who are on remote computers can access the company file using a database server which runs in Hosting Local Files only mode.
  • A computer that runs on this mode can host the files that are located on that computer.

Hosting Local & Remote Files mode

  • QuickBooks Database Manager runs as a normal process just like the currently Windows user. This process starts when the user logs into the Windows and the process stops as soon as the user logs out.
  • If a computer is running in this mode, then it can support multi-user mode in order to communicate with QuickBooks. However, do this using TCP/IP. QuickBooks users who work on remote computers can access company files using the database server.
  • In addition to this, a local computer that is running in this mode can also host the files that are stored on it and located on remote computers. These files can also be opened on the local computer.

How QuickBooks determines which database server to communicate with?

The ways in which QuickBooks Desktop determines the database server to communicate with, are as follows:

  1. QuickBooks looks for .nd file and this file is a small text file which has the same name as the company file but has an .nd file extension. Moreover, this text file is located in the same directory where the company file is located. The company file has the extension- .qbw. The details like IP Address and port, to contact the server are also available in the directory.
  2. QuickBooks Desktop also determines whether the .qbw file is in use or not.
  3. When QuickBooks Desktop find this text file, i.e. .nd file, then it also detects the company file that is in user. After this, the QuickBooks software tries to communicate with the server in the following manner:
    • If communication is successful, the company file will open by QuickBooks.
    • If communication is not successful, then an error message comes which describes the ways to resolve this issue. You can take a look at the Multiple computer receive error H101, H202, H303 and Error H505.

When the folder that contains file is not writable and is not shared

Make sure that the folder that contains the company file is available to the other users.

Important: If you are on a workstation then you should ignore this warning.

When there is no network connectivity:

Command Description
Ipconfig Basic TCP/IP information
