The best way is to use the method I outlined here in reverse:
http://www.dnncreative.com/Forum/ta...fault.aspxIn your localhost site go to admin / site settings and add the portal alias for your live website, eg: www.mywebsite.com
Create a backup of your local host SQL database
Upload the database to your hosting provider and ask them to restore the database
( after the restoration check that your username and password work to access your database)
Edit on your localhost site your web.config file so that the connection string points to your SQL database with your hosting provider.
Upload your localhost installation files to your hosting provider
Make sure ASP.NET 2.0 is enabled
Contact your hosting provider and ask them to ensure all permissions are correctly setup on the database and the DotNetNuke installation files
Navigate to your domain name and hopefully everything should be working correctly.
Hope this helps, thanks,
