This event library (Get-EventsLibrary.ps1) is PowerShell script that parses Security (mostly) logs on Domain Controllers. It has few reports capabilities including sending group membership changes, user changes, user lockouts, user creation, user password change. When setting up as Task Schedule it can send daily, monthly, quarterly reports to your email about changes happening in your domain. Please note this code has been deprecated and there's better, faster, more robust version called PSWinReporting. Same idea, but better execution. This code below is left for educational purpose only!
For example:
You can easily see the user being added or removed from Domain Admins group
You can easily change your HelpDesk agent did a change of password for your boss
Best of all since it's all read from Active Directory DC there is no way to tamper with it (unless someone clears out the logs of DC's but then you've got a bigger problem on your hands).
PSWinReporting Information
Please notice this article contains parts of information (still useful) and may not reflect all functionalities of this module. For download, source code and so on you should refer to the dedicated PSWinReporting module page. After reading this one… of course! It contains useful information, examples and know-how.
Usage of the script is quite simple. There are 2 scripts in play:
Get-Events.ps1 (or however you call it) – this your configuration script and script you actually setup for Task Scheduler
Get-EventsLibrary.ps1 – this is the main library doing all the heavy lifting. Do NOT modify it as most of the settings should be configured/disabled in the file above. This file is supposed to be easily replaceable with new versions when they come with more features, bug fixes and so on.
First file (Get-Events.ps1) contains all the configuration and a starter part. Make sure to fill out 3 hash tables as seen below:
$EmailParameters – have been tested on Office 365, tested on relays
$FormattingParameters – essentially branding of your report (logo size, log link, fonts used in report)
$ReportOptions – what should be run and when
Make sure the that GetEventsLibraryPath is correct.
$GetEventsLibraryPath = "C:\Support\Scripts\Includes\Get-EventsLibrary.ps1" # THIS IS REQUIRED!!
And then simply run the script. If you're lucky enough you will get it right the first try.
If not go thru errors reported. Try to enable just some reports, in the beginning, to see if the configuration file is correct.
You can find version changes below:
Version 0.8 – Updates from feedback. Lots of changes, new dates supported. Details can be found on separate blog post.
Version 0.7 – Updates from feedback. Details can be found on separate blog post.
Version 0.6 – Updates from feedback. Details can be found on separate blog post.
Version 0.5 – First Public Release

Following library Get-EventsLibrary.ps1 is core file for reporting of events via email.
Report Group Events
Report User Events
Report User Statuses
Report User Lockouts
Report Domain Controller Reboots – not finished
Report Logon Events – not finished
If you prefer to just copy/paste code below you can find full code for the Get-EventsLibrary.ps1.
Following error message is related to GetEventsLibraryPath being wrong.
WARNING: Get-EventsLibrary.ps1 not available. Please make sure to edit path to that library in global includes above - variable GetEventsLibraryPath. WARNING: In case you don't have the library you can always download it at https://evotec.xyz/hub/scripts/get-eventslibrary-ps1/
You should make sure to fill out

It's important to try and start the script manually first, before setting it up as Scheduled Task. When you run the script for the first time you may get following information:
Please make sure the config file matches new version requirements. This usually means following code is missing under $ReportOptions.
DisplayConsole = @{
ShowTime = $true
LogFile = ""
TimeFormat = "yyyy-MM-dd HH:mm:ss"
}Since script utilizes Write-Color function those options are needed for centralized settings.
You can also find yourself with some of the settings missing from the config file. Make sure to fix it up. It doesn't check the values, just that parameters exist. This feature is supposed to protect script from running if new Get-EventsLibrary.ps1 has some options that don't exist in the running report's script.

.NOTES
Version: 0.8
Author: Przemyslaw Klys <przemyslaw.klys at evotec.pl>
Creation Date: 23.03.2018
Modifcation Date: 15.04.2018
TODO:
- DirectoryPattern = $true # adds to reports path Hourly \ Monthly \ Quarterly \ Custom ("C:\Support\Reports\Hourly")
- Fixes for reports
Changelog 0.8 - 15.04.2018
Basic
- Rebuilt config file (again, sorry for that)
- Rebuilt Test-Configuration to report what's wrong with configuration (limited capability)
- Changes and fixes for Send-Mail function
- Few other changes
New Dates
- ReportPastHour - if it's 23:22 it will report 22:00 till 23:00
- ReportCurrentHour - if it's 23:22 it will report 23:00 till 00:00
- ReportOnDay - weekly report - choose a day to send the report
- ReportCurrentDayMinusDayX - goes back X days and shows just 1 day
- ReportCurrentDayMinuxDaysX - goes back X days and shows all days till today
- ReportCustomDate - custom dates
New reports:
- IncludeEventLogSize -
- Preparations for IncludeGroupPolicyChanges - doesn't work yet (DO NOT SET TO TRUE)
- Preparations for IncludeClearedLogs - doesn't work yet (DO NOT SET TO TRUE)
- Preparations for IncludeLogonEvents - doesn't work yet (DO NOT SET TO TRUE)
New options:
- SendMail - setting deciding if report should be sent (you may want to just keep the XLSX/CSV files)
- KeepReports - when set files are kept, if not files are deleted after sending
- Added AsCSV - althought it's easier to work with Excel
- JustTestPrerequisite - checks config file for errors and terminates
Changelog 0.7 - 27.03.2018
Basic
- Fixed display issues with Write-Color inconsistency
- Fixed small code optimizations
- Added error handling for event listng (would error out on Windows 2003 controllers) - only Windows 2008/R2 and up are supported
- Added Supported column
- Moved Test-Prerequisite from config file to Library
Changelog 0.6 - 25.03.2018
Basic
- Changed configuration settings
- Added option to attach excel files instead of inline html tables
- Added option to send via relay smtp (just put empty string in EmailServerLogin - probably port 25 but depends on configuration of server)
- Added verification if modules are available
- Added verification if Get-EventsLibrary.ps1 is available
- Added verification if configuration is consistent (all required options defined) - doesn't check for values - this should prevent possible issues with new versions of Get-EventsLibrary.ps1
- Added report for custom dates
- Added option to choose AsHTML or/and AsExcel - you can have Excel attached along with tables inline in email or just one of those
Changelog 0.5 - 23.03.2018
- First public version
Newest version of the script is always available at: https://evotec.xyz/hub/scripts/get-eventslibrary-ps1/

Function ConvertTo-FlatObject {
<#
.SYNOPSIS
Flatten an object to simplify discovery of data
.DESCRIPTION
Flatten an object. This function will take an object, and flatten the properties using their full path into a single object with one layer of properties.
You can use this to flatten XML, JSON, and other arbitrary objects.
This can simplify initial exploration and discovery of data returned by APIs, interfaces, and other technologies.
NOTE:
Use tools like Get-Member, Select-Object, and Show-Object to further explore objects.
This function does not handle certain data types well. It was original designed to expand XML and JSON.
.PARAMETER InputObject
Object to flatten
.PARAMETER Exclude
Exclude any nodes in this list. Accepts wildcards.
Example:
-Exclude price, title
.PARAMETER ExcludeDefault
Exclude default properties for sub objects. True by default.
This simplifies views of many objects (e.g. XML) but may exclude data for others (e.g. if flattening a process, ProcessThread properties will be excluded)
.PARAMETER Include
Include only leaves in this list. Accepts wildcards.
Example:
-Include Author, Title
.PARAMETER Value
Include only leaves with values like these arguments. Accepts wildcards.
.PARAMETER MaxDepth
Stop recursion at this depth.
.INPUTS
Any object
.OUTPUTS
System.Management.Automation.PSCustomObject
