These errors indicate communication problems between workstations and the server hosting the company file.
Understanding the root cause is essential before applying any fix. Below are the most common reasons:
Improper server hosting configuration may prevent multi-user access.
A corrupted network descriptor file blocks communication between systems.
Firewall settings may block QuickBooks ports required for multi-user connectivity.
If the service isn’t active, users won’t connect to the shared file.
Network instability often leads to QuickBooks H202 Error and related issues.
