what are you using for your ip?  Are you setting it too localhost, or using your real ip? 
 
Unable to get hostname indicates a dns lookup is failing, I would guess this could happen if you are using localhost instead of 127.0.0.1, or are hardcoding your dns name (someip.somewhere.com). 
 
You can also put localhost in your windows/smhost or hosts file. (Cant remember the exact file, not at my windows box right now)
