There are various files in QuickBooks Desktop apart from the company file. One such file is the Network Data (.ND) files which is knows as the configuration files in QuickBooks Desktop. This file is required for QuickBooks to access a company file in a network or multi-user environment. The QuickBooks Database Server Manager creates the .ND file because it allows QuickBooks to identify the database server the will use.

Sample .ND file

  • Server IP Address – Identify the Server IP address and then do a comparison whit the date that contained by the .ND file.
  • Server Name and QB Year – The server name is in the middle. The QuickBooks Database Manager version is at the end: 28=2018, 27=2017, 26=2016.
  • Port used – The port will be opened or added in the firewall setting.
  • Full path to company file – The path should be C: because any path other than this will require additional troubleshooting.
  • 1 for Hosting On; 2 for Hosting Off – Hosting should be enabled for the file that you want to open in a multi-user environment.
  • Usually blank – Usually blank and can be ignored.

About .ND files

  • The .ND file is stored in the same folder where your company file is saved and it has the same name as your company file but with an .ND file extension:
    • nd
    • qbw.nd
  • If you are currently on single-user mode but you have used multi-user mode in past, you will still have an .ND file.
  • The .ND file is 1 KB in size. It is basically a text formatted file and you can open or edit it in Notepad. It can be identified with a text icon.
  • The .ND files contains information that are required for QuickBooks to communicate with the server, primarily the IP address and port. It also identifies whether your company files are currently being used or not. Note: If you want to check the server name and IP address, that can be done by pressing F2 or CTRL + 1

Use and resolve .ND files errors

You won’t be able to work on your company file if the .ND file is damaged, missing or if the QBW file was moved during the time of update but the corresponding .ND file wasn’t moved. The .ND file can be viewed or recreated easily to resolve errors related to your company files. Here are some of the common errors:

  • Error H101, H202, H303, or H505
  • Error -6189, 816
  • Error -6150
  • Error -6175
  • Error -6000, 83
  • Error -6000, 77
  • Error -6143, 0

To resolve issues with .ND files (incorrect, missing, or damaged):

  • Open the Windows Explorer and go to the folder where your company file is located.
  • Locate *.ND in the folder. The file will have the same name as your company file but with the .ND file extension. Note: If you don’t find the .ND files, open a QuickBooks company file on the computer where the file resides to create it.
  • Remove or rename the files (.NDOLD).
  • Open the Database Server Manager to scan to folders again. Doing this will create new configuration files again.
