QuickBooks Error H202
Free Step-By-Step Fix Guide
QuickBooks Error H202 appears in multi-user mode when a workstation cannot communicate with the server hosting the company file. It usually means a firewall, service, or hosting configuration is blocking the connection.
Before You Start — Try This First
- Confirm the server computer is on and QuickBooks is open on it
- Check all computers are on the same network
- Restart your router if recently changed
Step-by-Step Fix
Run QuickBooks File Doctor
On the server computer, download QuickBooks Tool Hub → Company File Issues → Run QuickBooks File Doctor → Select your company file → Check your network → Wait for results
Check QuickBooks Services
On the server computer: Press Windows + R → Type services.msc → Find 'QuickBooksDBXX' (XX = your version year) → Right click → Start. Also find 'QBCFMonitorService' → Right click → Start
Configure Windows Firewall
On the server computer add these as firewall exceptions: QuickBooks Desktop, QuickBooksDBXX service, QBCFMonitorService. Go to: Control Panel → Windows Defender Firewall → Advanced Settings → Inbound Rules → New Rule → Program → Browse to QuickBooks → Allow connection
Check Hosting Settings
On the SERVER computer only: QuickBooks → File → Utilities → 'Host Multi-User Access' should be ON. On ALL WORKSTATIONS: QuickBooks → File → Utilities → 'Host Multi-User Access' must be OFF
Add Server to Hosts File
On each workstation: Open Notepad as administrator → File → Open → C:\Windows\System32\drivers\etc\hosts → Add a new line: [Server IP Address] [Server Name]. Save and close
Ping the Server
On a workstation, open Command Prompt: Type: ping [your server name]. If ping fails your network has a deeper connectivity issue
