Know What to Do When QuickBooks Hosting Mode Is Off

QuickBooks Desktop’s multi-user mode depends on a feature called Hosting Mode, which allows the server computer to share the company file with other workstations. If Hosting Mode is turned off—intentionally or accidentally—users will encounter errors like:

“QuickBooks is unable to open the company file in multi-user mode.”

“Error H202, H505, or 6000 series.”

This guide explains how Hosting Mode works, why it matters, and how to turn it back on safely and correctly.

🧭 What Is Hosting Mode in QuickBooks?

Hosting Mode enables the QuickBooks Database Server Manager to manage access to the company file across multiple users. It should be enabled only on the server that stores the company file—not on individual workstations.

⚠️ What Happens When Hosting Mode Is Off?

• Workstations cannot access the company file in multi-user mode
• QuickBooks may default to single-user mode
• You may receive network errors or file locking issues
• The server won’t manage file access, risking data conflicts
