i'm working on setting up an nntpcache server on our network. i thought i had everything set up correctly, and i can receive a list of available newsgroups from my server. however, when i try to subscribe to a group, i receive an error stating that the group is not available from my server. i know this is probably an easy one for some, but i'm kind of a dummy when it comes to usenet. any advice on this would be much appreciated. thanks, ron
