CR for VS2010 - Failed to open the connection.

40 Views

I have an ASP.NET application that access a SQL Server 2005 database. I am using impersonation with integrated security. The application was recently upgraded from .NET 3.5 to 4.0. The application works perfectly except for the reports. The Crystal Reports are not able to establish a connection to SQL Server when integrated securiy is set to true and no user ID or password are given. The error I receive is Failed to open the connection, Database Vendor Code 4060. If I supply a user ID and password, the reports work, but I would rather not do this.
