ASP.NET [Win32Exception (0x80004005): Access is denied] Error

When I test it in Visuall Studio by pressing F5 and it's working fine and I can able to login the webpage and sql query process working nicely. Also note that my SQL server is active over internet which can be accessed using IP address.

But when I publish my ASP.Net Website in myasp.net hosting service provider and and I am getting the login screen working nicely. But the problem is when I click login button I am getting the below error which is not occurring while testing in VS.

Server Error in '/' Application. Access is denied Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I don't think your provider will allow you to access a private sql like that. If that's the case you'll need to use a sql that is hosted and supported by your asp.net provider.

@Asken You're right... I received the following reply from the myasp.net customer support.

Dear Customer,

Sorry, for performance reasons, we don't allow our customer to connect to remote database server. We suggest you simply make a backup of your database and restore it to our server to test your application. You’ll see a much faster performance and reliability using this method.

However, if you must connect to a remote database server, please consider upgrading to our Premium Plan or Semi Dedi Plan. Once you upgrade to these hosting plans, you can enable any ports your want in your Control Panel -> Security Manager -> Outgoing Port Manager.

And don't worry, we provide a 60 days FULL Money Back for all of our plans.

Thank you.
