New-CertificateNotificationTask

  • Reference
Module:
PKI

Creates a new task in the Task Scheduler that will be triggered when a certificate is replaced, expired, or about to expired.

Syntax

New-CertificateNotificationTask
   -Type <CertificateNotificationType>
   [-RunTaskForExistingCertificates]
   -PSScript <String>
   -Name <String>
   -Channel <NotificationChannel>
   [-WhatIf]
   [-Confirm]
   [<CommonParameters>]

Description

The New-CertificateNotificationTask cmdlet creates a new task in the Task Scheduler that will be triggered when a certificate is replaced or expires. The task will launch the script specified by the PSScript parameter.

If the RunTaskForExistingCertificates parameter is specified, then after this cmdlet is registered, the cmdlet will go through all certificates (including archived certificates) in the My store and initiate Replace events for all certificates with a Renewal property. The NewCertHash value will always be the one at the end of the renewal chain. For example; if certificate A was renewed to certificate B, which was then renewed to certificate C, then the cmdlet fires two events: certificate A to certificate C and certificate B to certificate C. This will ensure that applications that are still using old certificates are properly updated to the newest certificates. If any certificate has a renewal chain longer than 20, then the certificate is not logged.

Examples

EXAMPLE 1

$params = @{
    PSScript = 'C:\myscript.ps1'
    Channel = 'System'
    Type = 'Replace'
    Name = 'My System Certificate Task'
}
New-CertificateNotificationTask @params

This example creates a system notification task for certificate replacement events with the name My System Certificate Task that will launch the C:\myscript.ps1 script. The cmdlet will run on the local system.

EXAMPLE 2

$params = @{
    PSScript = 'C:\myscript.ps1'
    Channel = 'User'
    Type = 'Expire'
    Name = 'My User Certificate Task'
}
New-CertificateNotificationTask @params

This example creates a system notification task for the expiration and close-to-expiration certificate events with the name My User Certificate Task that will launch the C:\myscript.ps1. The cmdlet will run for all currently logged on users in the user contexts.

Parameters

-Channel

Sets the channel of the CertificateServicesClient-Notifications log that will be monitored for certificate lifecycle events. The acceptable values for this parameter are:

Generates a replacement notification for any certificate in the My store that has been replaced in the past. For the notification to be generated both certificates must be present in the store. This parameter can only be used with the Replace type.

Note

The following warning is displayed when this parameter set to False and there are some certificates in MY store that would have resulted in a notification.

There are certificates in My store that have been replaced in the past. You can use the New-CertificateNotification cmdlet with the RunTaskForExistingCerts parameter to generate notifications for those certificates to correct any configuration problems that you may already have on this machine.

Type:SwitchParameter

Accept pipeline input:False
Accept wildcard characters:False

-Type

Specifies the type of events that will trigger certificate notifications. The acceptable values for this parameter are:
