I have 2 new servers that I've installed a fresh install of OES SP2 (not
an upgrade)

After installation everything works fine, I can hit https://ip and it
redirects to the welcome page. I can use imanager and remote manager,
all webservices work fine... until I install and configure cluster
services, then the welcome page stops coming up and imanager won't load,
all I get is a server error 500, internal server error. I can still
access remote manager with https://ip:8009

Exact thing happened on two servers, works fine until NCS is installed.
I am very new to SLES and could use some advice on where to start.
