Modifying the host file worked, thanks again for the reminder Dave. I didn't even think of doing that, as I thought for sure Comcast would have updated by now. It's been over a month since I changed hosts. Good news is that my IP will not change.
Bad news is that the one user who is still locked out typically needs a lot of hand holding. I'm skeptical he'll be able to make this update on his own. We'll see.
