This article applies to:

• WebMarshal 

Symptoms:

• New WebMarshal installation/configuration
• WebMarshal Engine does not start when the configuration wizard is completed
• Error: Cannot contact database, installation cannot continue 

Causes:

These symptoms can occur when

• The SQL Server is a named instance
• "Connect using TCP/IP" is not selected on the database settings window of the wizard.
• TCP/IP is required for connectivity due to the network environment

Resolution:

To resolve this issue, in the configuration wizard go back to the database window (or restart the wizard and proceed to this window). Select "connect using TCP/IP," then complete the wizard. 

Notes:

This problem has only been observed when all three causes are present.
