The guide:
1. The first thing you'll want to do is figure out the IP address of the site you're not able to get to. You can do this using the Windows command prompt (Start -> Run -> cmd):
The number listed next to the "Address" field is what you will be looking up.
2. After that, you'll need to know who owns the IP block of the site you're trying to reach. You can do this by checking ARIN, the corporation in charge of managing IP addresses in North America. Once you reach ARIN, paste the IP address in the "WHOIS" box near the top of the page.
You'll see something like this:

To make the admin's job easier you'll probably want to include a traceroute. If you already know how to do one, skip this part and go on to step 4. If not, read on:
