Greetings
I have created a report using WSDL of a published BI query. The report is developed in CR.net visual studio 2008 version & deployed on IIS 7.5.
When the url of web app hosting the report is typed in browser, a window prompt opens

Entering Login ID & password in last two parameters enables the report to run sucessfully. Keeping the parameters empty displays an empty report. My question is
- Why does this prompt occur ?
- How to suppress this prompt window ?
- Do i have to pass parameters programitically or through some setting in some file or on a server ?
Many Thanks
