Solutions to Fix QuickBooks Error H202

• Restart QuickBooks on all systems and try switching to multi-user mode.

2. Check Hosting Settings

• Open QuickBooks on each workstation.

• Go to File → Utilities.

• If you see Host Multi-User Access, do not select it (this means hosting is already enabled on the server).

3. Configure Windows Firewall

• Open Control Panel → System and Security → Windows Defender Firewall.

• Select Advanced Settings → Inbound Rules → New Rule.

• Add QuickBooks ports for your version (e.g., 8019, 56728, 55378–55382).

• Right-click and rename it to CompanyFile.qbw.nd.old.

• Re-scan the folder using QuickBooks Database Server Manager.

5. Test Network Connectivity

• Open the Command Prompt on your workstation.

• Type: ping [server name] and press Enter.

• If you do not receive replies, your workstation cannot connect to the server. Check network cables, connections, and permissions.

6. Use QuickBooks Connection Diagnostic Tool
