Detailed Solution Steps
Close QuickBooks and rename the corrupted network files:
- Close QuickBooks on all computers accessing the company file
- Navigate to the folder containing your .QBW company file
- Look for files with the same name as your company file but ending in .ND and .TLG
- Right-click the .ND file → Rename → Add ".OLD" to the end (e.g., MyCompany.qbw.ND.OLD)
- Repeat for the .TLG file
- If you see multiple .ND files (with numbers), rename all of them
Note: You're not deleting these files, just renaming them. This forces QuickBooks to create fresh, uncorrupted versions.
Force QuickBooks to recreate the network files:
- On the server computer, open QuickBooks Database Server Manager
- Go to Start Menu → type "Database Server Manager" → Open it
- Click the "Scan Folders" tab
- Click "Add Folder" and browse to your company file location
- Select the folder and click OK
- Click "Scan" and wait for the process to complete
- New .ND and .TLG files will be automatically created
Use Intuit's diagnostic tool to verify file integrity:
- Download QuickBooks Tool Hub if not already installed
- Open Tool Hub → Company File Issues tab
- Click "Run QuickBooks File Doctor"
- Select your company file from the dropdown
- Choose "Check your file" option
- Enter your QuickBooks admin password
- Wait 5-10 minutes for the scan to complete
Check permissions and test opening the file:
- On the server, navigate to the company file folder
- Right-click the folder → Properties → Security tab
- Ensure all users have "Modify" permissions
- Open QuickBooks on the server first
- Open the company file - it should open successfully
- If using multi-user mode, switch to multi-user (File → Switch to Multi-user Mode)
- Test opening from workstations

Frequently Asked Questions
What causes QuickBooks Error 6000-83?
Error 6000-83 occurs when the .ND (Network Descriptor) and .TLG (Transaction Log) files that QuickBooks uses to manage multi-user access become corrupted or damaged.
Will I lose data when fixing Error 6000-83?
No, fixing Error 6000-83 does not cause data loss. You are only renaming auxiliary files (.ND and .TLG), not modifying your actual company file (.QBW). Always create a backup first as a precaution.
What are .ND and .TLG files?
.ND files store network information for multi-user access, and .TLG files are transaction logs. QuickBooks creates these files automatically to manage file access and locking.
Can I delete .ND and .TLG files instead of renaming?
Yes, you can delete them, but it's safer to rename by adding ".OLD" so you have a backup in case something goes wrong. QuickBooks will recreate these files automatically.
