I’m runnning IIS 7 on my local dev machine. My website is up and running. To access the website, I need to enter the url with the port number in the browser’s address bar (www.ScoobyDoo.dev:91). What do I need to change so I only need to enter the http://www.ScoobyDoo.dev portion of the url? I’ve done this before but I’m drawing a blank. Port 80 is hosting a different website so I can’t just move this one to the default http port.
Thanks!
If you want multiple sites to reside on the same IP address then you need to use HTTP Host Headers.
Provided that your existing website doesn’t use SSL then you can use host headers. To configure host headers in IIS7 you modify the “Bindings” (there’s a menu item for this in the right hand side Actions pane for the site):
You want to add/edit your bindings for each site that resides on the same IP address, for example for your scoobydoo.dev site:

The caveat here is that if you have users already browsing your first site by IP address then they will need to be redirected to the site using its domain name.
You can do this by adding a site bound to the raw IP address and creating a HTTP Redirect.
