When I tried to create a new Sitecore Rocks connection to a Sitecore web site with the values specified in the image below, the following error occured:
The Web site does not respond.
It looks like the server address is a local web site. If the web site is running on ASP.NET Development Server, the server may not have been started yet.
Do you want to retry?
You might have already guessed the reason for this error.
But if you are like me who is not yet very experienced with configuring websites and who sometimes forgets what a "host name" is, here is the solution to that problem:
The "host name" here is the same as the "host name" of your website in IIS
