Network related or instance specific error occurred while establishing a connection KdoLib error 3566 when launching any Module on a Capture Workstation


QAID # 16346 Published

Question / Problem:

Kofax Capture clients in a client/server configuration are reporting the following error when launching any module:

"[3566] KdoLib: Network I/O error.: A network-related or instance-specific error
occurred while establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that SQL Server is
configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 -
Error Locating Server/Instance Specified) (-1)."

Why is this occurring and how can it be fixed?

Answer / Solution:

This can occur if the Kofax Capture installation was performed to a SQL Server database using a locally named instance. For example, using .\KofaxSQLDB instead of <Server_Name>\KofaxSQLDB in the ACConfig.XML file's SqlServerInstance element.

To resolve this issue, modify the ACConfig.XML file to reflect the SQL Server machine name as demonstrated above.
