I'm new to ASP.net and SQL server. I successfully connected my webform1.aspx page to my SQL database, created a SQLAdapter1 and dataset in Visual Studio.NET using the drag and drop technique. To connect I used my SA login and password. Testing the connection worked. I put a simple this.SQLDataAdapter1.Fill(this.dataset11); line in the Page_Load event in the code behind file. When I run the page in the brower I get an sa login failure. I looked through a few threads and saw that an ASPNET user may be what the browser is expecting so I created the ASPNET user with a password in SQL Server 2000 and gave it access to my database. I modified the connection string to the new ASPNET user and password. I'm getting the same sa login failure. Where is the sa login coming from? Thanks.
