not seeing articles in news reader?

[Jason]

so as a followup, heres what happens if I test with a telnet to port 119 of the news servers
and do the following:

telnet <servername> 119
group japan.rp
head 13914
quit

the old server works fine and returns the article, the new server returns
423 Bad article number

How can I fix this? that article is DEFFINATELY in the spool directory with the correct 
permissions. It looks like like the corresponding article on the old server.
Searching google it looks like i need to rebuild the overview? does this sound right?

regards,
Jason
