QuickBooks Error H505: Hosting Configuration Conflict
Quick Answer:
Error H505 occurs when multiple computers are trying to host the same QuickBooks company file. Fix it by disabling hosting mode on all workstations, leaving it enabled only on the server computer.
What is QuickBooks Error H505?
QuickBooks Error H505 is a hosting configuration error that occurs when multiple computers on a network are configured to host the same company file simultaneously. In a proper multi-user setup, only the server (or one designated computer) should host the company file, while all other workstations access it as clients.
Error H505: Hosting configuration conflict
Multiple computers are competing to host your QuickBooks company file, which prevents proper multi-user access.
Symptoms:
- •Cannot open company file in multi-user mode
- •Error message appears when switching to multi-user mode
- •Intermittent access issues for some users
- •QuickBooks freezes when opening the file
Resolution Steps:
- 1.Verify only server has hosting enabled
- 2.Check hosting settings on all workstations
- 3.Disable hosting on workstations
- 4.Restart QuickBooks and test connection
Quick Fix for Error H505 (3 Minutes)
Fastest Solution
- On each workstation, open QuickBooks Desktop
- Go to File → Utilities
- If you see "Stop Hosting Multi-User Access", click it
- Repeat for all workstations
- On the server, ensure "Stop Hosting" is showing (meaning hosting is ON)
- Try opening your company file in multi-user mode
Detailed Solution Steps
First, verify hosting is properly enabled on your server computer:
- Go to the computer that hosts your company file (the server)
- Open QuickBooks Desktop
- Click File → Utilities
- You should see "Stop Hosting Multi-User Access" (this means hosting is ON)
- If you see "Host Multi-User Access" instead, click it to enable hosting
- Leave QuickBooks open on the server
Visit each workstation computer and turn off hosting mode:
- On the first workstation, open QuickBooks Desktop
- Click File → Utilities
- If you see "Stop Hosting Multi-User Access", click it to disable hosting
- You should now see "Host Multi-User Access" in the menu (meaning hosting is OFF)
- Close and reopen QuickBooks
- Repeat these steps on every other workstation
Important: Every workstation must have hosting disabled. Even one workstation with hosting enabled will cause Error H505.
After changing hosting settings, refresh the configuration:
- Close QuickBooks completely on all computers
- Wait 10 seconds
- Open QuickBooks on the server first
- Open the company file
- Switch to multi-user mode (File → Switch to Multi-user Mode)
- Then open QuickBooks on workstations
Verify the hosting configuration is working correctly:
- On a workstation, open QuickBooks
- Navigate to your company file
- Open it normally (it should open in multi-user mode automatically)
- Verify you can access and edit data
- Test with multiple users simultaneously
Why Does Error H505 Occur?
Common Causes
- •Improper Initial Setup: Hosting was accidentally enabled on workstations during QuickBooks installation
- •File Moved Between Computers: Company file was moved from one server to another without reconfiguring hosting
- •Single-User Mode Testing: Users switched to single-user mode on workstations, which enabled hosting
- •QuickBooks Updates: Some updates can reset hosting settings, requiring reconfiguration
How to Prevent Error H505
Best Practices:
- Always designate one computer as the permanent server for hosting
- Document which computer is the server for your team
- Avoid using single-user mode unless absolutely necessary
- Check hosting settings after QuickBooks updates
- Train users to never enable hosting on their workstations
