SharePoint 2016 Managing Central Administration Web Application

Central Administration in SharePoint Server 2016 is where you go to perform administration tasks from a central location. SharePoint 2016 brings another improvement in this category as well. Now, Central admin will not be provisioned on all Servers in a farm by default. CA will be installed on the first Server in the farm on which you run the SharePoint Products Configuration Wizard.

Moreover, Central Administration site does not depend on the MiniRole. Now, you can provision Central Admin on any Server irrespective of their role in the farm (MiniRole). MiniRole Health will not try to provision or un-provision it.

There are 4 different ways to provision / Un-provision Central Admin to a Local Server.

  • The Services on Server page on Central Administration > System Settings
  • Windows PowerShell cmdlets (new-spcentraladmininstration)
  • The psconfig.exe -cmd adminvs operation
  • The SharePoint Products Configuration wizard
