Hi Daniele,
Thanks for commenting.
Now it is working.
It was a rather odd case.
If I typed upctv.ch in the browser then it defaulted to www.upctv.ch and produced an error.
I then tried ping from what used to be the DOS window.
If I pinged www.upctv.ch I got no response.
If I pinged just the server upctv.ch I got a normal reply.
If I interpret this literally it would mean the server was up, but not the www service.
