Recovering local articles that are not visible

[Nick Giles]

Hi all,

I'm trying to recover some articles which have been lost by our 
installation of inn. Our server is an internal only setup, so just a few 
local groups. We had a power cut a couple of days ago, and now one of 
the groups is reporting 'Bad article number' for all its (old) articles. 
I've had a poke around, and the articles are in the 'articles' folder 
area, and there are entries in the overview .DAT file that correspond. 
The 'active' file had its maxindex reset to 001, when it should have 
been 009 (yeah, not a huge group...)

My feeling is that the articles are just missing from some index, but 
now I've run into a bit of a brick wall of understanding. Which of the 
various databases / indexes do I need to update, and how do I do that? 
Is it the .IDX file for the group, and is there a way to rebuild the 
content of that from the content of the 'articles' directory?

Not knowing quite how to phrase the question has also resulted in some 
frustrating web search attempts...

Thanks in advance,

Nick
