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. .PARAMETER RunLevel Specifies the level of user rights that Task Scheduler uses to run the tasks that are associated with the principal. Defaults to 'Limited'. .PARAMETER LogonType Specifies the security logon method that Task Scheduler uses to run the tasks that are associated with the principal. .PARAMETER EventSubscription The event subscription in a string that can be parsed as valid XML. This parameter is only valid in combination with the OnEvent Schedule Type. For the query schema please check: https://docs.microsoft.com/en-us/windows/desktop/WES/queryschema-schema .PARAMETER EventValueQueries Specifies event value queries. This parameter is only valid in combination with the OnEvent Schedule Type. Receives a hashtable where the key is a property value for an event and the value is an XPath event query. For more detailed syntax check: https://learn.microsoft.com/en-us/windows/win32/taskschd/eventtrigger-valuequeries. .PARAMETER Delay Specifies a delay to the start of the trigger. This parameter is only valid in combination with the AtLogon, AtStartup, OnEvent, AtCreation and OnSessionState Schedule Types. .PARAMETER StateChange The kind of session state change that would trigger a task launch. This parameter is only valid in combination with the OnSessionState Schedule Type. #> function Test-TargetResource { [CmdletBinding()] [OutputType([System.Boolean])] param ( [Parameter(Mandatory = $true)] [System.String] $TaskName, [Parameter()] [System.String] $TaskPath = '\', [Parameter()] [System.String] $Description, [Parameter()] [System.String] $ActionExecutable, [Parameter()] [System.String] $ActionArguments, [Parameter()] [System.String] $ActionWorkingPath, [Parameter()] [System.String] [ValidateSet('Once', 'Daily', 'Weekly', 'AtStartup', 'AtLogon', 'OnIdle', 'OnEvent', 'AtCreation', 'OnSessionState')] $ScheduleType, [Parameter()] [System.String] $RepeatInterval = '00:00:00', [Parameter()] [System.DateTime] $StartTime = [System.DateTime]::Today, [Parameter()] [System.Boolean] $SynchronizeAcrossTimeZone = $false, [Parameter()] [System.String] [ValidateSet('Present', 'Absent')] $Ensure = 'Present', [Parameter()] [System.Boolean] $Enable = $true, [Parameter()] [ValidateSet('SYSTEM', 'LOCAL SERVICE', 'NETWORK SERVICE')] [System.String] $BuiltInAccount, [Parameter()] [System.Management.Automation.PSCredential] $ExecuteAsCredential, [Parameter()] [System.String] $ExecuteAsGMSA, [Parameter()] [System.UInt32] $DaysInterval = 1, [Parameter()] [System.String] $RandomDelay = '00:00:00', [Parameter()] [System.String] $RepetitionDuration = '00:00:00', [Parameter()] [System.Boolean] $StopAtDurationEnd = $false, [Parameter()] [System.String] $TriggerExecutionTimeLimit = '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.String] $IdleWaitTimeout = '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.String] $IdleDuration = '01:00:00', [Parameter()] [System.Boolean] $RestartOnIdle = $false, [Parameter()] [System.Boolean] $DontStopOnIdleEnd = $false, [Parameter()] [System.String] $ExecutionTimeLimit = '08:00:00', [Parameter()] [ValidateSet('IgnoreNew', 'Parallel', 'Queue', 'StopExisting')] [System.String] $MultipleInstances = 'Queue', [Parameter()] [System.UInt32] $Priority = 7, [Parameter()] [System.UInt32] $RestartCount = 0, [Parameter()] [System.String] $RestartInterval = '00:00:00', [Parameter()] [System.Boolean] $RunOnlyIfNetworkAvailable = $false, [Parameter()] [ValidateSet('Limited', 'Highest')] [System.String] $RunLevel = 'Limited', [Parameter()] [ValidateSet('Group', 'Interactive', 'InteractiveOrPassword', 'None', 'Password', 'S4U', 'ServiceAccount')] [System.String] $LogonType, [Parameter()] [System.String] $EventSubscription, [Parameter()] [Microsoft.Management.Infrastructure.CimInstance[]] $EventValueQueries, [Parameter()] [System.String] $Delay = '00:00:00', [Parameter()] [System.String] [ValidateSet('OnConnectionFromLocalComputer', 'OnDisconnectFromLocalComputer', 'OnConnectionFromRemoteComputer', 'OnDisconnectFromRemoteComputer', 'OnWorkstationLock', 'OnWorkstationUnlock')] $StateChange ) $TaskPath = ConvertTo-NormalizedTaskPath -TaskPath $TaskPath Write-Verbose -Message ($script:localizedData.TestScheduledTaskMessage -f $TaskName, $TaskPath) $currentValues = Get-CurrentResource -TaskName $TaskName -TaskPath $TaskPath # Convert the strings containing time spans to TimeSpan Objects if ($PSBoundParameters.ContainsKey('RepeatInterval')) { $PSBoundParameters['RepeatInterval'] = (ConvertTo-TimeSpanFromTimeSpanString -TimeSpanString $RepeatInterval).ToString() } if ($PSBoundParameters.ContainsKey('RandomDelay')) { if ($ScheduleType -notin @('Once', 'Daily', 'Weekly')) { # A random delay is only supported when the ScheduleType is set to Once, Daily or Weekly.
