How to fix QuickBooks H202 error using Windows network tools | Community
Skip to main content

I’m getting QuickBooks Error H202 when trying multi-user mode. The company file is on the server, but other users can’t connect. I’ve checked firewall and hosting settings, restarted services, but no luck. Anyone faced this? How do I fix the H202 error quickly? Thanks!

QuickBooks Error H202 occurs when you try to switch to multi-user mode, and QuickBooks cannot connect to the company file located on the server. This error means the workstation is unable to communicate with the server hosting the company file due to network or configuration issues.
