Microsoft SMB2 Hotfix (2024)

Microsoft has acknowledged that the Server Message Block Version 2 (SMB2) protocol may cause stability issues and data corruption in applications such as CaseWare® Working Papers (including SmartSync), which require real-time file information on files accessed over a network. Error messages in Working Papers, such as “Error -310: Not a ​correct index file” and “Inconsistent Database Indices Detected” may be due to data corruption caused by SMB2. Missing or corrupted SmartSync events can also occur when using SmartSync.

If you are using Working Papers 2015 or later on Windows 7 (including SP1) or Windows Server 2008 R2 (including SP1) operating systems and you are missing a Microsoft hotfix, the following message will appear:
