Frequently Asked Questions (FAQ)
FAQ One: What is the difference between QuickBooks Error 6010, 100 and Error -6094, 0 (6010, 2)?
These are related errors indicating similar underlying issues. Error 6010, 100 typically points to hosting configuration problems—specifically when a non-server computer is hosting the company file . Error -6094, 0 (6010, 2) usually indicates that antivirus software is blocking QuickBooks from starting the database server . Both errors require similar troubleshooting steps, but -6094,0 places more emphasis on checking antivirus and security software.
FAQ Two: Can antivirus software cause QuickBooks Error 6010?
Yes, antivirus software is a primary cause of QuickBooks Error 6010. Programs like AVG Anti-Virus, PC Tools Internet Security, and SpyHunter Malware are known to block QuickBooks processes, quarantine critical files such as qbdmgr.exe and qbdbmgrn.exe, and interfere with database server startup . If the error appeared shortly after an antivirus update or scan, temporarily disable your antivirus to test. If the error resolves, add QuickBooks exceptions permanently before re-enabling your antivirus .
FAQ Three: Why does Error 6010 appear only on my computer but others can access the company file?
This pattern indicates a local configuration issue, not a network or server problem . The affected workstation likely has hosting enabled incorrectly, has strict firewall settings blocking QuickBooks, or has a damaged QuickBooks installation. Check your hosting settings (Solution Two), verify firewall exceptions (Solution Seven), and run QuickBooks Tool Hub on your workstation (Solution Three). If the issue persists, try opening the company file using the local path if you are the hosting computer .
FAQ Four: What does the error message “An error occurred when QuickBooks tried to start the database server” mean?
This message indicates that QuickBooks cannot start the QuickBooks Database Server Manager that manages access to your company file . This commonly happens when antivirus software blocks the database server executable (qbdbmgrn.exe). Restore any quarantined QuickBooks files from your antivirus quarantine folder, add the QuickBooks installation directory to your antivirus exception list, and restart the QuickBooks Database Server Manager service on your server computer .
FAQ Five: Will reinstalling QuickBooks fix Error 6010 permanently?
Reinstalling QuickBooks can resolve QuickBooks Error Code 6010 if the cause is a damaged installation. However, if the root cause is incorrect hosting settings, firewall blocks, or antivirus interference, reinstalling will not help and may waste significant time . Always work through the solutions in order: verify hosting settings first (Solution Two), then configure antivirus exceptions (Solution Four), then check firewall settings (Solution Seven). Only proceed to clean reinstall (Solution Ten) after all other solutions have failed.
FAQ Six: How do I know if my company file is corrupted or if the issue is network-related?
If only one workstation experiences Error 6010 while others can access the file, the issue is network-related or local to that workstation, not file corruption . If no workstations can access the file, try copying the company file to your local drive and opening it directly. If the file opens locally, the issue is with network access or server configuration. If the file fails to open locally, the company file itself may be corrupted and require restoration from a backup .
FAQ Seven: Can Windows updates cause QuickBooks Error 6010?
Yes, Windows updates can reset firewall settings, change security policies, or update system components in ways that affect QuickBooks connectivity . If Error 6010 appeared shortly after a Windows update, check your firewall settings (Solution Seven), verify that QuickBooks services are running, and ensure your antivirus exceptions are still in place. Running the QuickBooks Install Diagnostic Tool (Solution Three) can also repair any compatibility issues introduced by Windows updates .

While the solutions above resolve most QuickBooks Error 6010 cases, certain scenarios require Intuit's advanced support team.
