Creates a new SharePoint Central Administration Web application.

New-SPCentralAdministration [[-Port] <Int32>] [[-WindowsAuthProvider] <String>] [-AssignmentCollection <SPAssignmentCollection>]

The New-SPCentralAdministration cmdlet creates a new Central Administration Web application and starts the central administration service on the local computer. Central Administration is available only on computers where this service runs.


Parameter Required Type Description




Specifies the port number for Central Administration. If no port is specified, a nonconflicting port number is auto-generated.

The type must be a valid port number.

If you specify a port number that has already been assigned, IIS does not start the new site until you change either the port number of the new site or the port number of the old site.




Specifies the authorization provider for this Web application. If no authentication provider is specified, the default value NTLM is used.

The type must be one of two values: Kerberos, orNTLM.




Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.


New-SPCentralAdministration -Port 3000

This example creates the Central Administration site at port 3000 on the local farm.
