Intuit has launched QuickBooks File Doctor tool (QBFD) in 2012. QuickBooks File Doctor is a tool that has been designed to recover the damaged company files and also helps in solving the network issues. There are test results as well each of the result has a section in it where all the result is described in detail along with the resources that can help fix the problem.
When the Hosting Mode is turned off
To access your QuickBooks files, you are required to 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 can be easily accessed by 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:
- QuickBooksDB28 is used by QuickBooks Desktop 2018
- QuickBooksDB27 is used by QuickBooks Desktop 2017
- QuickBooksDB26 is used by QuickBooks Desktop 2016
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.
The following diagrams illustrate QuickBooks hosting modes.

Ways to Access the Company Files
In order to access the company file, make sure that your system meets following conditions:
- Database Server Mode: The company file can be easily and successfully opened by the database server.
- QuickBooks User Login: Make sure that each user has a user login and password.
- Windows File Permissions: Ensure that if a user is logged in, then he must have the permissions to Full Control. These permissions also include permission to modify the files and to look at the file.
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 28 which has been determined by the version of QuickBooks) and also as the Windows user QBDataServiceUserXX (where XX is a 2-digit number from 17 to 28 which is used by the Windows Service).
- The service QuickBooksDBXX runs until the computer is on.
- To communicate with the QuickBooks software, multi-user mode is supported using TCP/IP. This is to be noted 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 is run as a normal process just like the currently logged on 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 but this has to be done 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:
- 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 stored in the directory.
- QuickBooks Desktop also determines whether the .qbw file is in use or not.
- 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:
When the folder that contains file is not writable and is not shared
Make sure that the folder that contains the company file is shared with the other users.
Important: If you are on a workstation then you should ignore this warning.
When there is no network connectivity:
Even when there is no network, one TCP/IP adapter that is working and that the hostname of the local machine is resolvable.
The IPConfig tool is very useful in verifying the TCP/IP configuration of the computer you are using. This tool helps to troubleshoot the problems by using QuickBooks on the network.
Some of the most common IPConfig commands are as follows:
|Ipconfig||Basic TCP/IP information|
|Ipconfig/ all||Detailed TCP/IP information|
|Ipconfig/ renew||Renew the IPv4 address for all network adapters|
|Ipconfig / release||Renew the IPv4 address for all network adapters|
Steps to run the ipconfig:
To verify the TCP/Ip configurations of your computer, you may find the IPConfig tool. This tool helps you to resolve & troubleshoot problems while using QuickBooks on a network.
- Select the Windows Start button.
- Enter CMD in the search field.
- From the list of results, choose Command Prompt.
- At the Command prompt, enter ipconfig and then, press Enter.
If you need any more information regarding this, then you can enter ipconfig/? At the command prompt or visit support.microsoft.com.
When there is network problem: IP reverse lookup is failed:
Check whether the Windows can produce an IP address from a hostname and reverse the process.
