I've tried to install vmware server 2 on a small business server 2008 host and IIS 7 stopped working. Everytime I tried to access any website on the server including OWA I get HTTP Error 503. The service is unavailable. I've tried to restart the IIS services and websites with no luck. Removed vmware server and the problem persists. There are no errors in the application logs concerning IIS or anything related. I'm stumped. Does anyone have an idea what's happenning here and how to fix it?
That's because VMware Server 2 installs a Web Server (Tomcat IIRC) on the host which is used for management that is conflicting with IIS.
