Not valid for AtLogon and AtStartup tasks .PARAMETER Ensure Present if the task should exist, Absent if it should be removed .PARAMETER Enable True if the task should be enabled, false if it should be disabled .PARAMETER ExecuteAsCredential The credential this task should execute as. If not specified defaults to running as the local system account .PARAMETER DaysInterval Specifies the interval between the days in the schedule. An interval of 1 produces a daily schedule. An interval of 2 produces an every-other day schedule. .PARAMETER RandomDelay Specifies a random amount of time to delay the start time of the trigger. The delay time is a random time between the time the task triggers and the time that you specify in this setting. .PARAMETER RepetitionDuration Specifies how long the repetition pattern repeats after the task starts. .PARAMETER DaysOfWeek Specifies an array of the days of the week on which Task Scheduler runs the task. .PARAMETER WeeksInterval Specifies the interval between the weeks in the schedule. An interval of 1 produces a weekly schedule. An interval of 2 produces an every-other week schedule. .PARAMETER User Specifies the identifier of the user for a trigger that starts a task when a user logs on. .PARAMETER DisallowDemandStart Indicates whether the task is prohibited to run on demand or not. Defaults to $false .PARAMETER DisallowHardTerminate Indicates whether the task is prohibited to be terminated or not. Defaults to $false .PARAMETER Compatibility The task compatibility level. Defaults to Vista. .PARAMETER AllowStartIfOnBatteries Indicates whether the task should start if the machine is on batteries or not. Defaults to $false .PARAMETER Hidden Indicates that the task is hidden in the Task Scheduler UI. .PARAMETER RunOnlyIfIdle Indicates that Task Scheduler runs the task only when the computer is idle. .PARAMETER IdleWaitTimeout Specifies the amount of time that Task Scheduler waits for an idle condition to occur. .PARAMETER NetworkName Specifies the name of a network profile that Task Scheduler uses to determine if the task can run. The Task Scheduler UI uses this setting for display purposes. Specify a network name if you specify the RunOnlyIfNetworkAvailable parameter. .PARAMETER DisallowStartOnRemoteAppSession Indicates that the task does not start if the task is triggered to run in a Remote Applications Integrated Locally (RAIL) session. .PARAMETER StartWhenAvailable Indicates that Task Scheduler can start the task at any time after its scheduled time has passed. .PARAMETER DontStopIfGoingOnBatteries Indicates that the task does not stop if the computer switches to battery power. .PARAMETER WakeToRun Indicates that Task Scheduler wakes the computer before it runs the task. .PARAMETER IdleDuration Specifies the amount of time that the computer must be in an idle state before Task Scheduler runs the task. .PARAMETER RestartOnIdle Indicates that Task Scheduler restarts the task when the computer cycles into an idle condition more than once. .PARAMETER DontStopOnIdleEnd Indicates that Task Scheduler does not terminate the task if the idle condition ends before the task is completed. .PARAMETER ExecutionTimeLimit Specifies the amount of time that Task Scheduler is allowed to complete the task. .PARAMETER MultipleInstances Specifies the policy that defines how Task Scheduler handles multiple instances of the task. .PARAMETER Priority Specifies the priority level of the task. Priority must be an integer from 0 (highest priority) to 10 (lowest priority). The default value is 7. Priority levels 7 and 8 are used for background tasks. Priority levels 4, 5, and 6 are used for interactive tasks. .PARAMETER RestartCount Specifies the number of times that Task Scheduler attempts to restart the task. .PARAMETER RestartInterval Specifies the amount of time that Task Scheduler attempts to restart the task. .PARAMETER RunOnlyIfNetworkAvailable Indicates that Task Scheduler runs the task only when a network is available. Task Scheduler uses the NetworkID parameter and NetworkName parameter that you specify in this cmdlet to determine if the network is available. #> function Get-TargetResource { [OutputType([System.Collections.Hashtable])] param ( [Parameter(Mandatory = $true)] [System.String] $TaskName, [Parameter()] [System.String] $TaskPath = '\', [Parameter()] [System.String] $Description, [Parameter(Mandatory = $true)] [System.String] $ActionExecutable, [Parameter()] [System.String] $ActionArguments, [Parameter()] [System.String] $ActionWorkingPath, [Parameter(Mandatory = $true)] [System.String] [ValidateSet('Once', 'Daily', 'Weekly', 'AtStartup', 'AtLogOn')] $ScheduleType, [Parameter()] [System.DateTime] $RepeatInterval = [System.DateTime] '00:00:00', [Parameter()] [System.DateTime] $StartTime = [System.DateTime]::Today, [Parameter()] [System.String] [ValidateSet('Present', 'Absent')] $Ensure = 'Present', [Parameter()] [System.Boolean] $Enable = $true, [Parameter()] [System.Management.Automation.PSCredential] $ExecuteAsCredential, [Parameter()] [System.UInt32] $DaysInterval = 1, [Parameter()] [System.DateTime] $RandomDelay = [System.DateTime] '00:00:00', [Parameter()] [System.DateTime] $RepetitionDuration = [System.DateTime] '00:00:00', [Parameter()] [System.String[]] $DaysOfWeek, [Parameter()] [System.UInt32] $WeeksInterval = 1, [Parameter()] [System.String] $User, [Parameter()] [System.Boolean] $DisallowDemandStart = $false, [Parameter()] [System.Boolean] $DisallowHardTerminate = $false, [Parameter()] [ValidateSet('AT', 'V1', 'Vista', 'Win7', 'Win8')] [System.String] $Compatibility = 'Vista', [Parameter()] [System.Boolean] $AllowStartIfOnBatteries = $false, [Parameter()] [System.Boolean] $Hidden = $false, [Parameter()] [System.Boolean] $RunOnlyIfIdle = $false, [Parameter()] [System.DateTime] $IdleWaitTimeout = [System.DateTime] '02:00:00', [Parameter()] [System.String] $NetworkName, [Parameter()] [System.Boolean] $DisallowStartOnRemoteAppSession = $false, [Parameter()] [System.Boolean] $StartWhenAvailable = $false, [Parameter()] [System.Boolean] $DontStopIfGoingOnBatteries = $false, [Parameter()] [System.Boolean] $WakeToRun = $false, [Parameter()] [System.DateTime] $IdleDuration = [System.DateTime] '01:00:00', [Parameter()] [System.Boolean] $RestartOnIdle = $false, [Parameter()] [System.Boolean] $DontStopOnIdleEnd = $false, [Parameter()] [System.DateTime] $ExecutionTimeLimit = [System.DateTime] '8:00:00', [Parameter()] [ValidateSet('IgnoreNew', 'Parallel', 'Queue')] [System.String] $MultipleInstances = 'Queue', [Parameter()] [System.UInt32] $Priority = 7, [Parameter()] [System.UInt32] $RestartCount = 0, [Parameter()] [System.DateTime] $RestartInterval = [System.DateTime] '00:00:00', [Parameter()] [System.Boolean] $RunOnlyIfNetworkAvailable = $false ) Write-Verbose -Message ('Retrieving existing task ({0} in {1})' -f $TaskName, $TaskPath) $task = Get-ScheduledTask -TaskName $TaskName -TaskPath $TaskPath -ErrorAction SilentlyContinue if ($null -eq $task) { Write-Verbose -Message ('No task found. returning empty task {0} with Ensure = "Absent"' -f $Taskname) return @{ TaskName = $TaskName ActionExecutable = $ActionExecutable Ensure = 'Absent' ScheduleType = $ScheduleType } } else { Write-Verbose -Message ('Task {0} found in {1}.

Specify a network name if you specify the RunOnlyIfNetworkAvailable parameter. .PARAMETER DisallowStartOnRemoteAppSession Indicates that the task does not start if the task is triggered to run in a Remote Applications Integrated Locally (RAIL) session. .PARAMETER StartWhenAvailable Indicates that Task Scheduler can start the task at any time after its scheduled time has passed. .PARAMETER DontStopIfGoingOnBatteries Indicates that the task does not stop if the computer switches to battery power. .PARAMETER WakeToRun Indicates that Task Scheduler wakes the computer before it runs the task. .PARAMETER IdleDuration Specifies the amount of time that the computer must be in an idle state before Task Scheduler runs the task. .PARAMETER RestartOnIdle Indicates that Task Scheduler restarts the task when the computer cycles into an idle condition more than once. .PARAMETER DontStopOnIdleEnd Indicates that Task Scheduler does not terminate the task if the idle condition ends before the task is completed. .PARAMETER ExecutionTimeLimit Specifies the amount of time that Task Scheduler is allowed to complete the task. .PARAMETER MultipleInstances Specifies the policy that defines how Task Scheduler handles multiple instances of the task. .PARAMETER Priority Specifies the priority level of the task. Priority must be an integer from 0 (highest priority) to 10 (lowest priority). The default value is 7. Priority levels 7 and 8 are used for background tasks. Priority levels 4, 5, and 6 are used for interactive tasks. .PARAMETER RestartCount Specifies the number of times that Task Scheduler attempts to restart the task. .PARAMETER RestartInterval Specifies the amount of time that Task Scheduler attempts to restart the task. .PARAMETER RunOnlyIfNetworkAvailable Indicates that Task Scheduler runs the task only when a network is available. Task Scheduler uses the NetworkID parameter and NetworkName parameter that you specify in this cmdlet to determine if the network is available. #> function Test-TargetResource { [OutputType([System.Boolean])] param ( [Parameter(Mandatory = $true)] [System.String] $TaskName, [Parameter()] [System.String] $TaskPath = '\', [Parameter()] [System.String] $Description, [Parameter(Mandatory = $true)] [System.String] $ActionExecutable, [Parameter()] [System.String] $ActionArguments, [Parameter()] [System.String] $ActionWorkingPath, [Parameter(Mandatory = $true)] [System.String] [ValidateSet('Once', 'Daily', 'Weekly', 'AtStartup', 'AtLogOn')] $ScheduleType, [Parameter()] [System.DateTime] $RepeatInterval = [System.DateTime] '00:00:00', [Parameter()] [System.DateTime] $StartTime = [System.DateTime]::Today, [Parameter()] [System.String] [ValidateSet('Present', 'Absent')] $Ensure = 'Present', [Parameter()] [System.Boolean] $Enable = $true, [Parameter()] [System.Management.Automation.PSCredential] $ExecuteAsCredential, [Parameter()] [System.UInt32] $DaysInterval = 1, [Parameter()] [System.DateTime] $RandomDelay = [System.DateTime] '00:00:00', [Parameter()] [System.DateTime] $RepetitionDuration = [System.DateTime] '00:00:00', [Parameter()] [System.String[]] $DaysOfWeek, [Parameter()] [System.UInt32] $WeeksInterval = 1, [Parameter()] [System.String] $User, [Parameter()] [System.Boolean] $DisallowDemandStart = $false, [Parameter()] [System.Boolean] $DisallowHardTerminate = $false, [Parameter()] [ValidateSet('AT', 'V1', 'Vista', 'Win7', 'Win8')] [System.String] $Compatibility = 'Vista', [Parameter()] [System.Boolean] $AllowStartIfOnBatteries = $false, [Parameter()] [System.Boolean] $Hidden = $false, [Parameter()] [System.Boolean] $RunOnlyIfIdle = $false, [Parameter()] [System.DateTime] $IdleWaitTimeout = [System.DateTime] '02:00:00', [Parameter()] [System.String] $NetworkName, [Parameter()] [System.Boolean] $DisallowStartOnRemoteAppSession = $false, [Parameter()] [System.Boolean] $StartWhenAvailable = $false, [Parameter()] [System.Boolean] $DontStopIfGoingOnBatteries = $false, [Parameter()] [System.Boolean] $WakeToRun = $false, [Parameter()] [System.DateTime] $IdleDuration = [System.DateTime] '01:00:00', [Parameter()] [System.Boolean] $RestartOnIdle = $false, [Parameter()] [System.Boolean] $DontStopOnIdleEnd = $false, [Parameter()] [System.DateTime] $ExecutionTimeLimit = [System.DateTime] '8:00:00', [Parameter()] [ValidateSet('IgnoreNew', 'Parallel', 'Queue')] [System.String] $MultipleInstances = 'Queue', [Parameter()] [System.UInt32] $Priority = 7, [Parameter()] [System.UInt32] $RestartCount = 0, [Parameter()] [System.DateTime] $RestartInterval = [System.DateTime] '00:00:00', [Parameter()] [System.Boolean] $RunOnlyIfNetworkAvailable = $false ) Write-Verbose -Message ('Testing scheduled task {0}' -f $TaskName) $CurrentValues = Get-TargetResource @PSBoundParameters Write-Verbose -Message 'Current values retrieved' if ($Ensure -eq 'Absent' -and $CurrentValues.Ensure -eq 'Absent') { return $true } if ($null -eq $CurrentValues) { Write-Verbose -Message 'Current values were null' return $false } Write-Verbose -Message 'Testing DSC parameter state' return Test-DscParameterState -CurrentValues $CurrentValues -DesiredValues $PSBoundParameters } |
