Where do you get this 'failed' message? Have you tried running it from the command line to see if you can get more information? Are you running it 'chrooted'? Have you had a look at the conf file to see whether that still makes any kind of sense?
If I were to take a wild guess, I would guess that you are running named chrooted and that part of the directory structure upon which this depends is damaged (remember that in a chrooted app, the paths need to be thought of relative to the directory which now seems to be '/', which isn't '/' ).
So, if my wild guess is correct, and there is every reason to believe it may not be, re-installing won't help, unless you also cure the actual problem.
