Understand the QuickBooks Error H202

The QuickBooks error H202 indicates an issue connecting to the company file through a remote connection, preventing multi-user access. Typically caused by firewall, connectivity or file permission problems, it emerges when hosting setup issues disrupt external login attempts.

Confirm Multi-User Mode Is Enabled

As H202 directly relates to remote connectivity barriers, first verify multi-user mode is activated within company file preferences. Navigate to Edit Preferences Accounting Select Multiple Users Can Share The Company Data File. If disabled, enable the setting and reconnect attempting multi-user access.

Inspect Company File Hosting Computer Connectivity

Multi-user mode relies on proper hosting computer network visibility so external machines connect for remote data access. Verify the hosting desktop properly connects to the local network and has a static IP address configured for connectivity. Assign a permanent IP if the computer uses dynamic addressing.

Check Hosting Computer Network Port Access

Remote access requires specific TCP and UDP ports remain open on the hosting machine to allow traffic through. Verify unused firewall software does not block the QuickBooks required ports including 8019. Leverage the QuickBooks Network Diagnostic Tool to automatically detect any blocked ports causing the H202 error during remote login attempts.

Authorize Access For Multi-User Mode Users

Even with remote connectivity verified, each external machine user still requires authorized access to utilize multi-user capabilities. Reconfirm permissions are enabled for each unique Windows user profile attempting remote access on their machines. Consider simplifying permissioning by having everyone utilize an Administrator account.

Examine Anti-Virus Or Security Software Interference

Overly intrusive or misconfigured anti-virus products sometimes block remote connectivity by mistaking legitimate network traffic as malicious. Add database connectivity .QBC files to security whitelist exceptions on the hosting desktop. Fully disable security software if issues persist to isolate products wrongly identifying remote access as threats.

Attempt Remote Access From Internal Network First

Before tackling wider connectivity issues past the hosting computer’s network, first have an external machine attempt accessing multi-user mode from the same local area network as the hosting desktop to isolate internal routing problems. With those eliminated as error causes, focus expands to addressing external network barriers behind routers and firewalls.

Forward The QuickBooks Remote Access Port

For external multi-user connections beyond the internal network, the hosting computer’s router must port forward to allow incoming traffic through to reach the desktop's IP address. In the router management UI, forward TCP port 8019 to the hosting machine's static IP enabling external QuickBooks remote connectivity needs.

Adjust Router And External Network Firewall Settings

With the forwarding configuration completed on the local router, any network firewalls protecting the greater external network also require adjusted to permit QuickBooks connectivity. Modify their policies to allow open communication inbound on TCP 8019, often by adding firewall exceptions. For public networks, consider restricting source access to a smaller subset of trusted IP address ranges for improved security.

Call Intuit QuickBooks Support To Troubleshoot

If mediating connectivity and permissions issues tied to the H202 error code do not restore multi-user access, call Intuit’s customer support technicians. Give temporary remote assistance permissions so they connect directly to hosting computers, isolate the network disruption and repair the multi-user environment utilizing customized tools and diagnostics beyond common troubleshooting techniques.

When the QuickBooks error H202 hits, carefully inspect hosting machine configurations, network traffic rules and remote user permissioning allowing external access to company files in multi-user mode. Open the proper ports and grant authorized account abilities to regain seamless remote connectivity.
