ISP is Internet Service Provider, or provider of your dialup account. That is more
likely to be a source
of problems than the news server.

Can you ask your telephone comapny to check your line for 33.6 data
transmission? Most will provide this service.

33.6 modems shouldn't get the problems that are common with 56k.

Because connection is lost during download, and MD-II is not handling
that well. That is just my theory. I'll test this by setting up a new
user account, and breaking transmission by dialing the phone until the
modem abandons the connection. This should simulate a bad line.

Internet couild learn a lot from Z-Modem!

It's possibly true, but I have not heard this before. Most users have
no problem with it
Ask your ISP--they may have logs of your connections and be able to
tell you why you lost connection. I hope they are not like mine. My
ISP just tells me to re-install Windows.
Also ask your phone company. It's possible they can find fault with
your line or installation that they can fix easily.
