Publisher has now saved the project as a web site and returned the view to the main window.  Your site is ready for upload.  Publisher does not have a built-in upload utility.  Its help file recommends using Microsoft's Web Publishing Wizard, though any FTP client would do. 

The following screens show how to use the Web Publishing Wizard to upload your site.  Tutorials on using other programs are also available.  To continue this tutorial click the 'Next' button below the screenshot. 
 

If Microsoft's Web Publishing Wizard is installed there should be a shortcut for it inside the Start Menu in one of two areas.  First click on Start and go to Programs.  The first place to look is in the Accessories directory, as shown below.  The second is in a directory for Internet Explorer, if one exists.  Once you find the shortcut click on it.  To continue this tutorial, click on 'Web Publishing Wizard' in the screenshot below.
 

This is the initial screen of Microsoft's Web Publishing Wizard.  It cautions that certain information is required to use the wizard.  The hostname, username, and password are all that most people will need.  Once this information has been obtained click 'Next.'  To continue this tutorial click 'Next' in the screenshot below.

Now choose 'FTP' from the dropdown list.  Doing so should enable your upload to go as smoothly as possible.  Once FTP is listed in the box click 'Next.'  To continue this tutorial click 'Next' in the screenshot below.
