I just checked through all the classes in the .NET framework and none of them support NNTP. Would you have a pointer to something usable under .NET to talk to an NNTP server?
The reason why I am interested in something like this is to build an NNTP-to-XML-RPC gateway. It could allow all the traffic on a given newsgroup to be mirrored on a weblog. Something to do over the week-end, it looks rainy. I'll give it a try in Perl. I found twomodules I can use and I have a good book on XML-RPC!
