Sunil,

This will take your time to experiment and figure it out. There is NO one correct answer. It varies from computer to computer. No one here will be able to assist you over a message board. You will have to engage with sites like connectionstrings.com to figure out what works on your computer.

Sorry, but this is the same answer I would give if you were trying to connect through C# or any other ODBC compliant connector, not just Automation Anywhere.
