This error is common during company file restoration, multi-user setups, or network file access, making it a significant hurdle for smooth operations.

Common Causes of QuickBooks Error 6123

Here are some possible reasons for encountering this error:

Corrupted company file or backup file
Damaged Windows user profile
Firewall or security software blocking communication
Interference from third-party applications like antivirus programs
Incorrect network setup or disrupted connection with the server
QuickBooks database service not running properly

Let’s walk through some reliable methods to troubleshoot and fix QuickBooks Error 6123:

1. Use QuickBooks Tool Hub

QuickBooks Tool Hub is a great first step for most common issues.

Steps:

Download and install the QuickBooks Tool Hub.
Open it and choose Company File Issues.
Run Quick Fix my File.
If the error persists, try the File Doctor from the same section.

2. Rename the .ND and .TLG Files

These files help QuickBooks connect and sync your company file.

Locate your company file folder.
Find files with extensions .ND and .TLG (same name as your company file).
Right-click and rename them by adding .OLD at the end.
Restart QuickBooks and try accessing the file again.

3. Move the Company File to a Different Location

Sometimes file path restrictions cause errors.

Copy your company file to a different local folder (e.g., Desktop).
Try opening it directly from the new location.
If successful, move it back or adjust permissions.

4. Check Hosting and Firewall Settings

Make sure your Hosting Settings are correct:

On each system, go to File > Utilities.
Ensure only the server system has “Host Multi-User Access” enabled.

Check your firewall and antivirus software to ensure QuickBooks isn’t being blocked.

5. Create a New Windows User Profile

If user profile corruption is suspected:

Create a new Windows admin user.
Log in with the new profile and open QuickBooks.
Try accessing the company file.
