Login Failed

[RN1]

I am working on WinXP Pro SP3, .NET 2.0 & SQL Server 2005 (Windows
Authentication). When I run a ASPX page that connects to SQL Server,
the following error gets generated:

Login failed for user 'RON\ASPNET'

where RON is my machine name. I came across a few posts which
suggested adding RON\ASPNET as a User in SQL Server Management Studio
Express (under Security--->Logins node). I did so but that didn't
resolve the problem.

Can someone please advice me how do I overcome this problem?

BTW, is Windows Authentication more secure or SQL Server
Authentication? Under what circumstances should one be preferred over
the other?

Thanks.

Are you sure you specified Windows authentication in your connection string?

Windows Authentication is more secure for an obvious reason that you don't
need to store and to pass the password.

You may also consider impersonating the ASPNET account as some other
account. It may help you in troubleshooting.

Sounds like an issue with your connection string. I would study that.

You need to add RON\ASPNET as a login to SQL Server 2005
and specify that login as a user of your database.

Adding the login is not enough.
You must also add the login name to the users for your database.

I prefer to use SQL Server authentication.
That way, I can use an ad-hoc user to authenticate.

Thanks friends for your suggestions.

Yes...yes...that's where I was erring. I didn't add the login name to
the users for the database. After adding that login, I can now connect
& retrieve data from the database.

Thanks once again,

Regards.
