With IIS Manager you get a graphical overview of your web.config file, so you can easily change and fine-tune the IIS setup so that it fits exactly to your needs. It is also possible to eg. recycle one's Application Pool with IIS Manager.
You can download IIS Manager here: http://www.iis.net/download/iismanager
When you connect select "Start page" and then "Connect to site"
Login information is the same as for FTP and Web Deploy:
Recycling of Application Pool is done by right-click on the site in IIS Manager and then selecting "Deploy" -> "Recycle ...". Stop your Application Pool and start it again.
Through IIS Manager you can also convert a folder to an application. This is done by right-click on the folder, selecting "Deploy" and then "Convert to application"
