Failed to download from Internet

The following codes are downloading a text file from the Internet. It looks simple and straight forward.

$u2 = "https://my-test-web.com/my-file.txt"
$f2 = "my-file.txt"
Invoke-WebRequest -Uri $u2 -OutFile $f2

The above code looks good and we never expect download failure except that Internet connection has broken down.

But, if you look at the value of $u2, you might notice that it is calling HTTPS which require Powershell to validate the SSL certificate. So, there is a chance for the above code failed when the web server disabled Tls v1.1 and below.

To resolve/avoid this issue, you must change the environment setting first before calling Invoke-WebRequest.

# enforce Tls1.2
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

 $u2 = "https://my-test-web.com/my-file.txt"
$f2 = "my-file.txt"
Invoke-WebRequest -Uri $u2 -OutFile $f2

Scheduled task in Windows Task Scheduler - part 3

This is the last part of Task Scheduler - security context which is created using New-ScheduledTaskPrincipal. Usually, we are using S4U logon type for any server scheduled task + Highest Run Level. S4U details as per MS documentation: Use an existing interactive token to run a task. The user must log on using a service for user (S4U) logon. When an S4U logon is used, no password is stored by the system and there is no access to either the network or encrypted files. You can find more information in this page:     https://docs.microsoft.com/en-us/windows/win32/taskschd/principal-logontype For any user ID that you specified to run the scheduled task, it requires "Log on as a batch job" or "Log on as a service". You can find the details here:     https://docs.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/log-on-as-a-batch-job     https://docs.microsoft.com/en-us/windows/security/threat-protection/...

Create scheduled task in Windows Task Scheduler

Windows Task Scheduler is a utility that helps to execute any process periodically. For example, you want to sync your working files on daily basis, scanning virus, process some data, etc. A task has the following components: Action or multiple actions - which is the process that you want to run periodically. We use New-ScheduledTaskAction to create new action object. Trigger - which is the time to run the process and it can have multiple timing. We use New-ScheduledTaskTrigger to create new trigger. Security context - any process must run in a valid security context. We can set the context using New-ScheduledTaskPrincipal. The following script creates an on demand task which requires user to manually trigger the task. $task_folder = "\myTasks\" $task_name = "myTask2" # this can be any Powershell script. $ps_script_file = "d:\temp5\test-script.ps1" ## The first line will show err if $task_folder does not exist. ## The second line will not...
