post Moss 2007 installation configuration

after the Moss2007 install, a new wizard started another round. basically update the current two databases - one is the configuration, another is content database. 
some services cannot be run because my Moss is in standalone mode not in a domain.

But when I tried to open the web site, surprisingly I got an error in red  like

/ runtime error

need change web.config
remote mode off/on

also there is an extra line appsetting/ > ... just delete this un-matched line. \

then the web site sprung to life, ... well bit slower than before
