I was trying to enable some module on my server for some reason (I really don't know what module or why now), and now I cannot get Apache2 loaded. When I do, I get this error message:

Starting httpd2 (prefork) httpd2-prefork: sytax error on line 115 of /etc/apache2/httpd.conf: Syntax error on line 29 of /etc/apache/sysconfig.d/loadmodule.conf: Cannot load /usr/lib/apache2-prefork/mod_proxy_ajp.so into server: /usr/lib/apache2-prefork/mod_proxy_ajp.so: undefined symbol: proxy_module

I have been poking around and tweaking here and there and really all I am doing is making it worse. What is the easiest way to simply reinstall apache, imanager and those services. Kind of like reset them back to initial settings. I don't want to reinstall the whole server since I am using it for other purposes.
