INstalling a Newsserver

Hi there, I wonder if anyone here has installed a news-server into an NT domain. What I want is to use a Linux box, running SuSE8.0Pro to run the news server. I want it to connect to news.schoolzone.co.uk, but only download the newsgroups I tell it to download, and then only connect 10 times between 8am and 6pm. Any ideas or advice would be welcome.
