Understanding QuickBooks Error Code H202

QuickBooks Error Code H202 typically occurs when a user attempts to access a company file in multi-user mode, and the software is unable to establish a connection with the server hosting the company file. This can disrupt workflow and hinder collaboration, making it crucial to address the issue promptly.


Causes of QuickBooks Error Code H202


Incorrect Hosting Configuration:

One of the primary reasons for this error is an incorrect hosting configuration. Ensure that only the server is hosting the company file, and other workstations are set to access it in multi-user mode.


Firewall or Security Software Blocking Communication:

Firewalls or security software on the server or workstations may block the communication needed for QuickBooks to function in multi-user mode. Adjust firewall settings to allow QuickBooks through.


Damaged Network Data File (.ND):

The Network Data File (.ND) could be damaged, preventing QuickBooks from accessing the company file in multi-user mode. Re-creating the .ND file may resolve the issue.


Incorrect QuickBooks Database Server Manager Settings:

Incorrect settings in the QuickBooks Database Server Manager can also lead to Error Code H202. Ensure that the Database Server Manager is installed and configured correctly.
