Let’s go through several tested and proven solutions to fix this issue permanently.
The easiest way to fix this error is by using the QuickBooks File Doctor, a diagnostic tool provided by Intuit.
Download and install the QuickBooks Tool Hub (latest version).
Open the Tool Hub and click on Company File Issues.
Select Run QuickBooks File Doctor.
Browse your company file and click Check your file.
Enter your QuickBooks Admin credentials.
Allow the scan to complete — it may take 10–15 minutes depending on file size.

If the error persists, contact QuickBooks Technical Support at +1-888-394-9046 for further help.
The .ND (Network Data) and .TLG (Transaction Log) files allow multi-user access. If these files are damaged, QuickBooks can’t connect to your company file.
Open the folder that contains your company file.
(Default path: C:\Users\Public\Documents\Intuit\QuickBooks\Company Files)
Locate the files with the same name as your company file but with .ND and .TLG extensions.
Example:
CompanyName.qbw.nd
CompanyName.qbw.tlg
Right-click each file and choose Rename.
Add the word OLD at the end of each filename (e.g., CompanyName.qbw.nd.OLD).
Open QuickBooks again and try to access the file.
QuickBooks will automatically create new versions of these files when you reopen your company file.
If you still can’t open it, call QuickBooks Support +1-888-394-9046 for remote troubleshooting.
Sometimes, multiple users try to access the same company file in Single-User Mode, triggering error -6190, -816.
Ask all users to log out of QuickBooks.
Restart all systems connected to the network.
Open the company file on the Host computer in Multi-User Mode.
Go to File > Switch to Multi-User Mode.
Now, try to access the file from other workstations.
If the problem persists, call QuickBooks Multi-User Support at +1-888-394-9046.
Sometimes, hosting the company file on an external or network drive causes access issues.
Copy your company file (.QBW) from the server or external drive.
Paste it on your local desktop.
Open QuickBooks and try to open the company file from this location.
If it opens successfully, the issue may be with your network connection or server settings.
If you are not sure how to fix your network setup, contact QuickBooks Network Experts at +1-888-394-9046.
The QuickBooks Database Server Manager is essential for multi-user mode functionality.
Open the QuickBooks Tool Hub.
Click on Network Issues.
Select QuickBooks Database Server Manager.
Click Start Scan on your company file folder.
Once done, try to reopen the file in multi-user mode.
