Hi,
I am running the following configuration:
Windows Server 2003 Enterprise Edition SP2
ASP.NET 2.0
SQL Server 2005
I currently have a website in IIS that has ASP.NET enabled. I have a
login.aspx page which has the login box with the username and
password. When I click the login box, I want asp.net to check the SQL
database to check if the username and password are valid, and then
continue to a destination page. However, I receive an error when I
click Login.
-------------------------------------------------------------------------------------------------------------------
An error has occurred while establishing a connection to the server.
When connecting to SQL Server 2005, this failure may be caused by the
fact that under the default settings SQL Server does not allow remote
connections. (provider: SQL Network Interfaces, error: 26 - Error
Locating Server/Instance Specified)
Source Error:
An unhandled exception was generated during the execution of the
current web request. Information regarding the origin and location of
the exception can be identified using the exception stack trace below.
Stack Trace:

I have tried to do the following, but to no avail. I went into the SQL
Server Management Studio and right clicked on the server, and selected
Properties. I then went under Connections and made sure "Allow Remote
Connections to this server" was enabled. I also setup in SQL Service
Area Configuration to enable both Local and TCP/IP protocols. In IIS,
I have the database string for SQL as the following:
Data Source=.\MSSQLSERVER2005;Initial Catalog=aspnetdb.mdf;Integrated
Security=True
I am not sure what else to try. Am I missing something here?
