QuickBooks Error 6073 can appear when QuickBooks Desktop cannot properly open or access a company file. The issue is commonly associated with the company file already being open elsewhere, incorrect folder permissions, network-file access, or a remote-access session that has not closed correctly. Intuit currently identifies -6073, -99001 as an error that can occur when QuickBooks is unable to open a company file.
For a business using QuickBooks Desktop every day, this problem can interrupt bookkeeping, invoicing, payroll preparation, reconciliation, and other accounting activities. Fortunately, the cause can often be isolated by checking how the company file is stored and accessed.
What Is QuickBooks Error 6073?
QuickBooks Error 6073 is generally associated with difficulty opening a company file because QuickBooks detects an access conflict or cannot establish the expected connection to the file.
The problem can occur when:
- The company file is open on another computer in Single-User Mode.
- The company file is stored in a read-only network folder.
- Network permissions do not provide adequate access.
- A remote-access program has left a previous session active.
- Several computers are incorrectly configured for hosting.
- The network connection to the company-file location is unstable.
- QuickBooks configuration files related to network access have become damaged.
Intuit's current guidance specifically lists Single-User Mode on another computer, a read-only network folder, certain Linux-server credential configurations, and remote-access sessions among possible causes of error -6073, -99001.
Understanding the cause before changing settings is important because the same error message can have different underlying causes.
How to Recognize Error 6073
The most obvious symptom is that QuickBooks Desktop refuses to open the company file. You may see a message indicating that QuickBooks cannot open the company file because it may already be open by another user.
Other signs can include:
- The company file opens on one computer but not another.
- Multi-user access stops working.
- QuickBooks repeatedly asks you to reopen the file.
- A workstation cannot access a company file stored on the server.
- The problem occurs after using remote-access software.
- Other QuickBooks company files open normally while one particular file does not.
If only one company file is affected, the location, permissions, or file configuration deserves particular attention.
Fix 1: Close QuickBooks on Every Computer
Start with the simplest check.
Close QuickBooks Desktop on every workstation connected to the company file. This helps eliminate a session conflict before you change network or Windows settings.
After closing QuickBooks everywhere, open it on the computer that hosts the company file.
If the company file opens normally, check the hosting configuration before allowing other users to connect.
Intuit recommends closing QuickBooks Desktop on all computers and then opening the company file on the host when the file is open elsewhere in Single-User Mode.
Fix 2: Switch to Multi-User Mode
If your business uses the same company file from multiple computers, confirm that the host is configured correctly.
Open the company file on the host computer and select the appropriate option for Multi-User Mode.
If the file was accidentally opened in Single-User Mode, other workstations may be unable to access it as expected.
QuickBooks Desktop uses hosting and database services to manage access to company files in a multi-user environment. Intuit explains that successful access depends on appropriate Windows file permissions, the database server being able to open the file, and valid QuickBooks user credentials.
Fix 3: Check the Company File Folder Permissions
A company file stored on a network needs appropriate Windows permissions.
Navigate to the folder containing the .QBW company file on the host computer. Review the folder's security settings and verify that the affected Windows user has appropriate access.
A read-only or restricted folder can prevent QuickBooks from opening or modifying the company file correctly.
Intuit specifically identifies a read-only network folder as one possible cause of -6073, -99001 and recommends checking folder security permissions when this occurs.
Avoid randomly changing permissions throughout the computer. Concentrate on the folder containing the QuickBooks company file and apply access only to the users and systems that legitimately need it.
Fix 4: Check Remote-Access Sessions
Remote-access software can sometimes leave a session appearing active after the user has disconnected.
If the company file is being accessed through remote software, completely close the remote session and QuickBooks Desktop. Then restart the host computer if necessary.
Intuit lists remote-access situations among the potential causes of Error 6073 and recommends using QuickBooks Tools Hub's Quick Fix my Program in certain remote-access scenarios.
This is particularly relevant when the error began immediately after a remote session or when another computer appears to have control of the file.
Fix 5: Check the Network Connection
When the company file is stored on another computer, verify that the workstation can communicate with the host.
A network interruption can prevent QuickBooks from reaching the company-file location. Intuit's guidance for company-file access problems includes checking network connectivity and server accessibility when files are stored across a network.
Check that:
- The host computer is powered on.
- The network connection is active.
- The shared folder is accessible from the workstation.
- The company-file location has not been renamed or moved.
- The user can access the required folder with the appropriate Windows permissions.
If the shared folder itself cannot be reached from Windows File Explorer, troubleshoot the network before making changes inside QuickBooks.
Fix 6: Use QuickBooks File Doctor
QuickBooks File Doctor can be useful when company-file or network problems are suspected.
It is available through QuickBooks Tools Hub and is designed to check certain company-file and network-related problems.
Intuit recommends using QuickBooks File Doctor for Error 6073 troubleshooting.
If File Doctor identifies a problem, follow its results carefully. Avoid repeatedly modifying the original company file without having a recent backup.
Fix 7: Check for Multiple Hosting Computers
In a multi-user environment, incorrect hosting settings can create access conflicts.
Review the hosting configuration on the workstations and make sure the intended host is configured appropriately.
Intuit explains that hosting mode is configured for each QuickBooks Desktop installation and computer rather than being a property of the company file itself.
If multiple workstations are attempting to host the same company file unnecessarily, correcting the hosting configuration can help eliminate file-access conflicts.
Fix 8: Check the Company File Location
If the problem continues, determine whether the file location itself is responsible.
Create a copy of the company file and, for diagnostic purposes, attempt to open the copy from a local location. Do not replace your production file with a test copy unless you have confirmed the file is safe and current.
Intuit notes that moving a company file temporarily can help determine whether the original file location is causing an opening problem.
This test can distinguish between a file-related problem and a network-folder problem.
Fix 9: Review the .ND and .TLG Files
QuickBooks Desktop creates configuration files associated with company-file access, including Network Descriptor (.ND) and Transaction Log (.TLG) files.
If these files become damaged, they can contribute to company-file access problems. Intuit recommends renaming damaged .ND or .TLG files in certain company-file errors; QuickBooks can recreate these files when necessary.
Before making changes, ensure that you are working with the correct company-file folder and that a recent backup is available.
When QuickBooks Error 6073 Keeps Returning
A recurring Error 6073 should not simply be dismissed each time it appears.
Repeated errors may indicate an unresolved network configuration, incorrect permissions, a hosting conflict, damaged configuration files, or a problem with the company-file environment.

Can Error 6073 Cause Data Loss?
Error 6073 itself is an access problem and does not automatically mean that your accounting data has been erased.
However, when troubleshooting a company file, avoid deleting, overwriting, or replacing files without understanding their purpose. Maintain a current backup before performing significant file or configuration changes.
If a company file shows signs of data damage in addition to the access error, the situation requires separate investigation.
Is Error 6073 the Same as Every 6000-Series Error?
No. QuickBooks has several 6000-series company-file errors, and their causes can differ.
For example, Intuit documents separate troubleshooting procedures for errors such as -6000, -77 and -6000, -301. These may involve file locations, .ND and .TLG files, permissions, encryption software, or other configuration issues.
Therefore, it is better to troubleshoot the exact error code shown on the screen rather than applying a generic 6000-series solution.
