Resolution

The above error message indicates that connection string names LocalSqlServer is being used in the machine.config file. You have to override this setting to point to your connection string name which is used in the application’s web.config file.

This can be done by clearing, removing and adding connection string name in your web.config file as shown below.

<connectionStrings>
<clear />
<remove name=”LocalSqlServer ” />
<add name=”LocalSqlServer” connectionString=”Server=SQL_SERVER_HOST; User ID=YOUR_USER_NAME;password=YOUR_PASSWORD;Database=YOUR_DATABASE_NAME;Persist Security Info=False” providerName=”System.Data.SqlClient” />
<add name=”ASPNETDBConnectionString” connectionString=”Server=SQL_SERVER_HOST; User ID=YOUR_USER_NAME;password=YOUR_PASSWORD;Database=YOUR_DATABASE_NAME;Persist Security Info=False” providerName=”System.Data.SqlClient” />
</connectionStrings>

Add the above code to your web.config file, update the variables mentioned in capital letters and upload to your web server. Your application should work fine now.
