# Get-ProvServiceInstance

Gets the service instance entries for the MachineCreation Service.

Syntax

Get-ProvServiceInstance [-AdminAddress <String>] [<CommonParameters>]

Detailed Description

Returns service interfaces published by instances of the MachineCreation Service. Each instance of a service publishes multiple interfaces with distinct interface types, and each of these interfaces is represented as a ServiceInstance object. Service instances can be used to register the service with a central configuration service so that other services can use the functionality.

You do not need to configure a database connection to use this command.

Parameters

Name Description Required? Pipeline Input Default Value
AdminAddress Specifies the address of a XenDesktop controller the PowerShell snap-in will connect to. You can provide this as a host name or an IP address. false false Localhost. Once a value is provided by any cmdlet, this value becomes the default.

The Get-ProvServiceInstance command returns an object containing the following properties.
ServiceGroupUid
Specifies the unique identifier for the service group of which the service is a member.
ServiceGroupName
Specifies the name of the service group of which the service is a member.
ServiceInstanceUID
Specifies the unique identifier for registered service instances, which are service instances held by and obtained from a central configuration service. Unregistered service instances do not have unique identifiers.
ServiceType

Address
Specifies the address of the service instance. The address can be used to access the service and, when registered in the central configuration service, can be used by other services to access the service.

This indicates that the service provides a Windows Communication Foundation endpoint that uses HTTP binding with integrated authentication.
Version
Specifies the version of the service instance. The version number is used to ensure that the correct versions of the services are used for communications.

ServiceAccountSid
Specifies the Active Directory account security identifier for the machine on which the service instance is running.
InterfaceType
Specifies the interface type. Each service can provide multiple service instances, each for a different purpose, and the interface defines the purpose. Available interfaces are:
SDK - for PowerShell operations
InterService - for operations between different services
Peer - for communications between services of the same type
