I am basically a SharePoint developer but also an Admin by accident. I have 2 SharePoint(2013) servers (CompanyNameWeb and CompanyNameApp) and 2 SQL Servers in Production envt. Central admin url is http://CompanyNameApp:9000. Not sure when, but in CompanyNameWeb server the "Central Administration" services is Stopped. Of course the site is running fine, but does it need to be turned for good reason?
