The QuickBooks Database Server Manager (QBServerUtilityMgr.exe) exists to create .ND (Network Data) files. These are configuration files that allow QuickBooks to access a company file in a network or multi-user environment.
An .ND file identifies the database server the program will use. A single-user environment that previously had multi-user access turned on also will contain .ND files.
An .ND file is created in the same folder as the company file and is identified with the addition of .nd:
An .ND file is 1 KB in size. It is a text file that can be opened with and edited in Notepad. .ND files are identified with a text icon.
Files include the information QuickBooks needs to communicate with the server, primarily the IP address and port. It also detects whether the company file is in use.
Sample .ND File (this is what you will see if you open the .ND file in notepad).
Viewing and recreating .ND files can help resolve errors when a company file will not open. Common errors include H101, H202, H303, H505, and -6189, -82. A company file will not open if the .ND file is damaged, incorrect, or if the .QBW file was moved during an upgrade without moving the corresponding .ND file.
The easiest way to resolve an issue with .ND files (incorrect, missing or damaged) is to search the computer containing company files for “*.ND” (remove “ “ when searching). Delete or rename the files (.NDOLD) then use the Database Server Manager to rescan the folders. This will create new files. If no .ND file exists, opening a QuickBooks company file on the computer where the file resides will create it.
