  • Nope not yet. I think it will bring down all other sites right? Moreover will it use existing database while creating new central admin or it will create brand new central admin?

Go into powershell on one of your SharePoint 2013 servers and use Get-SPServiceInstance in order to get the Central Administration and Web Application service instances on the box you are targeting.

Then once you have the two GUIDs for those two instances - use the following for both the web application and central administration services.

Stop-SPServiceInstance <GUID>
Start-SPServiceInstance <GUID>

This will essentially recreate the web application in IIS.

  • try Get-SPServiceInstance | select TypeName, Status, Id, Server | out-gridview and it should be typename, Microsoft SharePoint Foundation Web Application and Central Administration make sure the ID correlates with the Server you are trying to stop/start

  • thanks. Now I am able to run the powershell and I can see central admin in IIS and it is online. However, when I browse central admin, it is authenticating for credentials always even after entering farm admin credentials. Do I need to complete any other step?

Run SharePoint Products Configuration Wizard on that server.

  • Press "Next"
  • Make sure the right database server and database is selected
  • Make sure "Do not disconnect from this server farm" is selected
  • Press "Next"
  • Press "Advanced settings"
  • Make sure to select "Use this machine to host the web site" in "Host Central Administration Web Application" window
  • Press "Ok"
  • Press "Next"
  • Wait for configuration to finish

Then Central Administration is installed properly on this machine.

  • Very good explanation of Phil. This won't delete any of your sites. But it will interrupt availability of your farm, as all services will get stopped while Products Configuration Wizards does it's work.

  • If Phils solution does not work, first select "Yes, i want to remove the web site from this machine" (means: CentralAdmin only). This will remove the broken components of your CentralAdmin. Then follow Phils steps again to redeploy CentralAdmin.

  • Thanks for clarification. I will do this during after hours and give you an update. I have two app servers which runs central admin and seems to be issue from both the servers now.
