Log in failed for user error

Question

Hi,

 

When I configure and  browse my local built application from IIS it launches the first page and while trying to fetch data from DB by search value, it throws error as below

 

Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'xxxxx' 

 

Itsauenticated with windows mode on config file.

 

Kindly let me know what kind of configration is missed to achieve ..

 

 

Thanks
