On a Windows computer, go to Start->Run and type "command" in the box(cmd if you're on Windows 2000/XP).
A box should appear. This is the "DOS Prompt", the legend only the IT dudes speak about.
In here, type "ping my-pedigree.com" without the quotes. If you get a result saying "Request timed out", then it's something wrong with the connectiion. If it says "Could not find remote hostname"(or something alongside that), then it's a DNS error and you should talk to someone in the IT department.(Or ask for more help)
