It looks like you are using WebTV as your ISP. First I would like to offer
some advice. NEVER use your real address in a newsgroup. You will be spammed
like crazy. I don't know what kind of interface WebTV uses for Usenet. The
Microsoft newsgroups are available from the Microsoft website or a
newsreader. On the website you can sign up for any nickname you want and
your address can be hidden. In a newsreader you can change the return
address to a throwaway one from sites such as Yahoo. Maybe someone who uses
WebTV could give you advice on your setup.
