When I try to connect to the Borland news server, I get an error that says there is no DNS entry for newsgroups.borland.com. Why?
It sounds like you may be behind a corporate firewall that has access blocked on port 119, the NNTP port. You will need to talk to your network administrator about opening your firewall on port 119. If you are not behind a firewall, the “no DNS entry” error could indicate a problem with your local DNS. Contact your ISP about this problem.
