How to: Implement Simple Forms Authentication Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 .NET https://msdn.microsoft.com/en-us/library/xdt4thhy.aspx Framework 3.0 Visual Studio 2005 .NET Framework 1.1 The example in this topic presents a simple implementation of ASP.NET forms authentication. It illustrates the fundamentals of how to use forms authentication to log users into an ASP.NET application. Note A convenient way to work with forms authentication is to use ASP.NET membership and ASP.NET login controls. ASP.NET membership provides a way to store and manage user information and includes methods to authenticate users. ASP.NET login controls work with ASP.NET membership and encapsulate the logic required to prompt users for credentials, validate users, recover or replace passwords, and so on.

MyASP.NET applicationis setup in two folders. Thetop folder has the default.aspx form. In the web.configI have set it to Forms authentication:

In the subdirectory I have the page which receives the redirection from the login. The form authentication in web config in the subdirectory has:

Both pages bind controls to a SQL Database on the same server. The first page comes up with no problems. After logging in, the second page comes up with the error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) In the database, I have given the ASPNET account permissions for the database and tables. I am using the same connection string for both pages. In the code behind for the login page, I only do this: Why am I getting the error after doing the Forms Authentication.
