A few days ago, a buddy of mine and I decided to start a webpage and a related forum. A friend of my wife's hosts these things so I set up an account with him. Within a couple of days, we were up and running. The host (my wife's friend) told me that he was switching to a larger server. From that point on, I have been unable to access the website or the related forum from my home computer. My computer runs Windows XP and has a Comcast cable internet connection. Everyone else I have asked is able to access the website and related forum, (it is listed as my webpage). I can access any other internet site from my computer. The only non-working combination is the website / forum and my home computer. The host doesn't have a clue right now and I asked my IT department at work and they were stumped. Hopefully someone here as a clue.
