Users must log in as Windows admin before taking the steps mentioned in this section.

① Renaming The .ND file

💠 First, the folder containing the company file must be opened and then users must locate the .ND file that corresponds to their company file. For example, it could be Company File Name .qbw.nd.
💠 After right-clicking on the .ND file, choose Rename and then add .OLD and select Enter. For example, it could be CompanyFileName.qbw.nd.OLD.
💠 If the company file is being used in many computers, users might have to set up the QuickBooks Database Server Manager.

Copying Company File To Another Location

💠 After creating a new folder, users must go the folder where the company file is stored. Now, the QuickBooks Error 6129, 0 company file (.QBW) must be copied.
💠 It is very important that the .QBW is being copied and not files like .ND and .TLG.

Setting up Folder Permissions

Checking That Permissions Are Properly Set

Users must right-click on the folder containing the company file and then choose Properties. Then, choose Advanced in the Security tab.
Next, choose QBDataServiceUserXX and then select Edit. Then, it should be checked that these settings are in Allowed mode:

➤ Traverse Folder/Execute File
➤ List Folder/Read Data
➤ Read Attributes
➤ Read Extended Attributes
➤ Create Files/Write Data
➤ Create Folders/Append Data
➤ Write Attributes
➤ Write Extended Attributes
➤ Read Permissions

If Permissions Aren’t Set Properly, These Steps Should Be Taken:

💠 After right-clicking on the folder containing the company file, users must choose Properties and then choose Security, followed by Edit.
💠 Next, users must choose QBDataServiceUserXX and then Full Control, followed by Allow. Then, Apply should be chosen, followed by OK.

Changing Folder Permissions

💠 First Windows + E must be pressed, which will open File Explorer. Then, go to the folder and choose Properties.
💠 These steps will have to be taken for all folders on the list. But all folders might not apply to every installation, as they point to a particular QuickBooks version. Contact our QuickBooks Error Code 6129, 0 experts for more information.

③ Restarting Computer In Safe Mode

④ Ensuring All Computers Are In Same Domain

If a domain is being used, users must contact whoever has set up their network.
