about_ConfigConfigurationSnapin

The Configuration service PowerShell snap-in provides administrative 
functions for the Configuration service.

All commands in this snap-in have the noun prefixed with 'Config'.

The Configuration service PowerShell snap-in enables both local and remote 
administration of the Configuration service.  It provides facilities to 
store details about other services that are used in the XenDesktop 
deployment.

All the services in the XenDesktop deployment use the Configuration service 
as a directory to locate other services with which they need to 
communicate.  The directory publishes a list of all the services, the  
communication types they accept, and the facilities they offer.

The snap-in provides the following main entities:

Site Metadata 
    Metadata for the entire XenDesktop deployment.  This metadata is not  
    used directly by any of the XenDesktop services, but can be used by 
    third parties to store information for other purposes.

Registered Service Instances 
    Service instance items that have been retrieved from the available 
    services in the XenDesktop deployment and held in a directory in the 
    Configuration service.  Each physical service can host a collection of 
    service instances to provide different facilities.

Service Groups 
    A collection of service instances that are considered equivalent. 
    Service instances that are registered in the same service group provide 
    the same state and offer the same functionality.

    Only one service group of each type is supported.  For example, there 
    must not be more than one service group with a ServiceType of 'Config'.

Site and Features 
    The configuration site is a top-level, logical representation of the  
    XenDesktop site, from the perspective of the configuration services  
    running within the site.
