Error 6129 0 Troubleshooting When You Access the File Locally

Accessing the company file locally means you are trying to open your file on the same computer where your QuickBooks Desktop is installed. In such cases, the following solutions will apply for QuickBooks error 6129 0:

Solution 1: Rename The Configuration Files

Network Data (.ND) and Transaction Log (.TLG) files are essential configuration components of QuickBooks (QB), facilitating access in multi-user or network settings. When these files become corrupted, it hinders user to access QB files. Fixing this error involves renaming these files and triggering their recreation during a Database Server Manager scan without data loss:

1. Navigate to the directory containing company files.
2. Identify files with .ND and .TLG extensions matching your company file name (e.g., SRPCompany.qbw.nd, SRPCompany.qbw.tlg).
3. Right-click each file, select “Rename,” and add .OLD at the end (e.g., SRPCompany.qbw.nd.old, SRPCompany.qbw.tlg.old).
4. Reopen QuickBooks and attempt to enter your company file. If the issue persists, proceed to the next solution for QuickBooks error 6129

Solution 2: Open A Sample QuickBooks Company File

To address the error 6129, it is crucial to understand whether the issue is in QuickBooks or the company file. Testing by opening a sample company file is a valuable diagnostic step. If errors occur during this process, it suggests a potential problem with the QuickBooks installation. So, follow these steps to open the sample company file and look for errors:

1. Click “Open a Sample File” in the No Company Open window and tap any sample file from the list.
2. If the sample file opens without errors, proceed to the next solution for addressing QuickBooks error code 6129.
3. In case the sample files encounter issues, rectify your installation files using Quick Fix My Program and the QuickBooks Install Diagnostic Tool from the QB Tool Hub.

Solution 3: Copy QuickBooks Files & Paste to the Desktop

In this troubleshooting step, we will investigate whether QuickBooks errors 6129 0 are associated with the location of your company file. To perform this assessment, we will copy the company file to the desktop and attempt to open it from there. Our analysis will yield the following observations:

1. If the file successfully opens from the desktop, it suggests potential damage to its original location.
2. The file might be situated within an excessive number of folders, surpassing file path limitations.
3. If relocating the file does not resolve the issue, it could indicate underlying file damage.

Follow these instructions to copy and paste your company file to the desktop for assessment:

1. Navigate to the folder holding the company file.
2. Right-click on the .QBW file, and tap Copy.
3. Move to the desktop, right-click on any blank part of the screen, and select Paste.
4. Subsequently, while holding the Ctrl key, launch QuickBooks to access the No Company Open window.

8. Once the file is prepared, click Save. If any prompts appear regarding potential data overwriting, choose the option that corresponds with your preferences, being mindful to avoid unintentional overwrites.

Troubleshooting Tips for QB Error 6129 when You Open a File over Network

Here are the troubleshooting tricks for QB error 6129 when you access the company file saved on the server or another system:

Fix 1: Verify the Hosting Settings for Workstations

To begin resolving error 6129, let’s examine the hosting settings on all workstations to ensure multi-user access is not enabled anywhere except on your server system:

1. Open QuickBooks on your workstation and press the F2 key.

3. Verify that hosting is set to OFF

Fix 2: Rename the Configuration Files & Use the Database Server Manager

2. In the tool hub, navigate to Network Issues, then select QuickBooks Database Server Manager.
3. If QuickBooks is not yet installed on your server, go ahead and install it.
4. Once you get into the QuickBooks Database Server Manager, choose Start Scan if your company file(s) are visible. If not, manually locate your company file and hit Start Scan.
5. Subsequently, open QuickBooks again and attempt to access your company file.

If the QB error 6129 persists, proceed to fix 3. You can also access the QuickBooks Database Server Manager directly from the Start menu by searching for it and opening it.

5. You can now access the QuickBooks company file in multi-user mode.
6. If the error 6129 persists, proceed to Fix 6.
