RPM reinstall

["Stuart Otway" <stuart moveassist com>]

Hi there,

Somebody (me) has screwed around with apache and changed the settings.  I
want to just reinstall the apache rpm file so I try :

rpm -e apache.rpm
(to uninstall)
and it says 'not installed'

then when I try to reinstall:
rpm -i apache.rpm
i get the message 'already installed'

what can I do?

is there a RPM command that forces a re-install. or forces a remove?

thanks a mil,
Stuart
