Fix Error Code 6073 QuickBooks Unable
Open Company File

Users seeking to access their business data may encounter the annoying obstacle of Error Code 6073 in QuickBooks. This issue usually means that QuickBooks cannot open the company file because it is in use by another user or because it is on an inaccessible computer. Several things, such as user mistake, file corruption, or network problems, may bring it on. In this article, we’ll look at how to resolve Error Code 6073 in QuickBooks so you may resume successfully handling your financial data.

Before You Begin

  1. Create a backup of your business file before starting any troubleshooting. This will help you avoid losing any data.
  2. Verify Multi-User Mode is Off: If attempting to open the file in multi-user mode, temporarily switch to single-user mode for troubleshooting.

Causes of Error Code 6073 

The most frequent cause of QuickBooks Error Code 6073 is a problem with accessing or opening a business file. You may easily avoid and resolve this problem by being aware of its root causes. Here are a few typical reasons why Error Code 6073 occurs:

  1. Numerous Users Trying to Access the Same QuickBooks Business File at the Same Time: When numerous users try to access the same QuickBooks business file simultaneously in multi-user mode, one of the leading causes of Error Code 6073 is this. QuickBooks may not handle this correctly, causing conflicts and access problems.
  2. Company File Location: This error may occur if the QuickBooks company file is kept on a computer or network location inaccessible or has modified its path. The file may have been relocated or destroyed, or the network connection may have been interrupted.
  3. File Already Open: The business file may cause Error Code 6073 if it is open on another computer or in a separate instance of QuickBooks on the same computer. To avoid data corruption, QuickBooks may limit the number of users accessing the file concurrently.
  4. Network Problems: Difficulties opening the corporate file may result from issues with your network settings, including problems with network routers, switches, or firewalls. Slow connection or network outages might make this issue worse.
  5. Inadequate Folder Permissions: Inadequate Folder permissions might prohibit QuickBooks from accessing the business file. Error Code 6073 may appear if the corporate file folder is not correctly shared or if the user does not have the appropriate access rights.
  6. Corrupted.ND and.TLG Files: To access and monitor business file changes, QuickBooks employs Network Data (.ND) and Transaction Log (.TLG) files. If these files are damaged or corrupted, QuickBooks can have trouble opening the company file and produce the error.
  7. Overly strict firewall or security software settings may prevent QuickBooks from connecting to the corporate file: Access problems may result from security software wrongly identifying QuickBooks as a possible threat.
  8. Host Mode Not Enabled: The host computer’s hosting mode must be enabled for multi-user mode to work. On the computer where the corporate file is kept, if this mode is deactivated, it may result in Error Code 6073 when other users try to access the file.
  9. Incompatible QuickBooks Versions: Using several QuickBooks releases or versions on various machines in a multi-user configuration might cause compatibility problems. Ensure that the same QuickBooks release and version are installed on all users.
  10. User Locking the File: Occasionally, a user may unintentionally and unknowingly leave the corporate file open, preventing other users from accessing it. This might happen when a user minimizes QuickBooks or leaves it running in the background.

To effectively troubleshoot Error Code 6073, it is essential to comprehend its causes. You may take focused action to address the problem and guarantee easy access to your QuickBooks business file by determining the fundamental cause.

Now, let’s delve into the solutions for Error Code 6073

Solution 1: Verify User Permissions

  1. Ensure that you have the necessary permissions to access the QuickBooks company file. If you are not the administrator, contact your IT department or the person who set up QuickBooks for your organization to grant you the required access.
  2. Confirm that no other user is simultaneously accessing the company file in multi-user mode. If they are, ask them to log out and close QuickBooks.

Solution 2: Resolve Network Issues

  1. Verify that all computers in your network are properly connected and have no connectivity issues.
  2. Restart your computer and the server where the company file is located. Sometimes, a simple restart can resolve network-related problems.
  3. Ensure that the company file folder is shared correctly and that the shared folder permissions allow full access.
  4. Turn off any firewall or security software temporarily to check if they block QuickBooks from accessing the company file. If turning off the firewall resolves the issue, you may need to reconfigure it to allow QuickBooks access.

Solution 3: Use QuickBooks Database Server Manager

  1. Download and install QuickBooks Database Server Manager on the computer where your company file is located.
  2. Run the Database Server Manager and scan the company file folder. This will help QuickBooks detect and resolve any network-related issues.
  3. After the scan completes, try to open the company file again from another computer.

Solution 4: Close All QuickBooks Processes

Solution 5: Rename.ND and . TLG Files

  1. On the computer where the company file is stored, navigate to the folder containing your company file.

  3. Rename both files by adding “.old” to their extensions (e.g., “MyCompanyFile.qbw.ND.old” and “MyCompanyFile.qbw.TLG.old”).
