Here is a list of Power Shell Scripts that are too cool to ignore
Windows and AD Scripts
SCVMM Powershell scripts

For the uninitiated:

Symbol	Meaning
%	shortcut for foreach object
$_	current object in the pipeline
Get-Member	Will list the fields of the object you send it
Sort-Object -Property [property name]	Will sort the objects you send in by the property name(s) which can be a comma separated list
Where-Object {$_.property -like 'string'}	Will filter the objects. Also short cut notation: ? {$_.property -like 'string'}
Get-Command -Module PSWindowsUpdate	Lists all the commands in the PSWindowsUpdate module

Windows and AD Scripts

Expand all zip files into directories with zip name

   1 $list = Get-ChildItem | ? { $_.Name -like "*.zip" } | select Name
   2 foreach ($line in $list) {
   3     $parts = $line.Name.Split(".")
   4     $outDir = ".\" + $parts[0]
   5     $inFile = $line.Name
   6     mkdir $outDir
   7     Expand-Archive $inFile -DestinationPath $outDir 
   8 }

List of Listening Ports with their owning programs

   1 $listening = (Get-NetTCPConnection | ? {($_.State -eq "Listen") -and ($_.RemoteAddress -eq "0.0.0.0")})
   2 foreach ($l in $listening) {
   3     $procid = $l.OwningProcess
   4     $proc = Get-Process -PID $procid | SELECT ID,ProcessName
   5     Write-Host $($l.LocalPort) "||" $($procid) "||" $proc.ProcessName
   6 }

List of AD accounts and the last time they logged in

   1 Get-ADUser -Filter * -SearchBase "dc=home,dc=scotnpatti,dc=com" -ResultPageSize 0 -Prop CN,samaccountname,lastLogonTimestamp | 
   2      select CN, samaccountname,@{n="lastLogonDate";e={[datetime]::FromFileTime($_.LastLogonTimestamp)}}

Delete AD User accounts that have not been used in X days

   1 $DaysAgo = (Get-Date).AddDays(-180)
   2 #Get-ADUser -Filter {Enabled -eq $True} -Properties LastLogonDate | ? {($_.LastLogonDate -le $DaysAgo)  } | FT Name, SamAccountName, DistinguishedName, LastLogonDate
   3 Get-ADUser -Filter {Enabled -eq $True} -Properties LastLogonDate | ? {($_.LastLogonDate -le $DaysAgo)  } | Remove-ADUser -Confirm

Delete AD Computer accounts that have not been used in X days

   1 $YearAgo = (Get-Date).AddDays(-370)
   2 Get-ADComputer -Filter * -Properties * | ? {$_.LastLogonDate -le $YearAgo } | Remove-ADObject -Recursive -Confirm 
   3 #Get-ADComputer -Filter * -Properties * | ? {$_.LastLogonDate -le $YearAgo } | FT Name, LastLogonDate -AutoSize

List Memory Installed

   1 Get-WmiObject win32_physicalmemory | Format-Table Manufacturer,Banklabel,Configuredclockspeed,Devicelocator,Capacity,Serialnumber -autosize

List object from Registry - namely version of .NET installed

   1 gci 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' | sort pschildname -des | foreach-object {$_.name; $_.GetValue("Version");}

Remote commands

   1 Invoke-Command -ComputerName eve -ScriptBlock { date }

Replace a string in a file using a regular expression

So I downloaded a bunch of files from "the way back machine" site and I needed to update the hard-coded links to be relative site links. The following little script did it for me.

   1 $files = ls Level*.html
   2 foreach ($item in $files) {
   3     (Get-Content -path $item) | % { $_ -Replace '(https://web.archive.org/nebula/level)([0123456789]{2})/', 'Level$2.html' } | Set-Content $item
   4 }

Adding DNS records to Windows DNS - For CPTR 446 class

   1 Import-Csv googleips.csv | ForEach-Object {
   2     Add-DnsServerResourceRecordA -Name $_.DNSName -ComputerName dc1.cs.southern.edu  -ZoneName cs.southern.edu $_.IP
   3 }

SCVMM Powershell scripts

I needed this once when I was trying to refresh the Library share. It failed on refresh with an error saying that a DVD was in use and wouldn't refresh until it was no longer in use. The following commands allowed me to identify the machines.

In general all of these need:

   1 Import-Module VirtualMachineManager

Get a list of Virtual Machines that have a DVD attached

   1 Get-SCVMMServer -ComputerName Samuel
   2 Get-SCVirtualMachine | Get-SCVirtualDVDDrive | Where-Object {$_.Connection -eq "ISOImage"} | Select Name, Connection, ISO

List VMs at the end of the semester to be deleted

   1 Get-SCVirtualMachine | Select Name, MarkedAsTemplate, Owner | Sort-Object -Property Owner, Name | Export-Csv -Path .\vms2019w.csv

Get a list of VM Mac Addresses for CPTR 427

   1 Get-SCVirtualMachine | Where-Object { $_.Name -like "*427*" } | select -ExpandProperty VirtualNetworkAdapters | select MacAddress

Setting up a Windows 2019 Server for the first time

Install the server - follow prompts.
Setup the AVMA key as shown below OR use sconfig in the next step.

   1 # Install the AVMA key.
   2 slmgr /ipk TNK62-RXVTB-4P47B-2D623-4GF74
   3 
   4  1. 
   5 
   6 #First run sconfig and setup the name, timezone and network, remote management and remote desktop. You can also setup windows update from here. 
   7 
   8 # Next we need to install Windows update and get it started.
   9 # This will install nuget package too.
  10 Install-Module PSWindowsUpdate
  11 
  12 # Now start the update process
  13 #   First we'll look at what updates are there
  14 Get-WUInstall 
  15 #   Now install them
  16 Install-WindowsUpdate

See the NAT setup near the bottom! That appears to have negated the need to change firewall rules. Also, I was not able to connect to the system via Server Manager right away. But a few minutes later, I could. No changes were made. But for posterity, they are here:

   1 # To turn on or off the firewall 
   2 Get-NetFirewallProfile
   3 # to set firewall on or off
   4 Set-NetFirewallProfile -Name Domain,Public,Private -Enabled True
   5 
   6 #Te get/set the firewall rule for private networks to allow any machine on a private network.
   7 Get-NetFirewallRule | ? {$_.DisplayGroup -like "Windows Remote Management*" -and $_.Profile -like "*Private*"} | Get-NetFirewallAddressFilter #Shows the address filter
   8 Get-NetFirewallRule | ? {$_.DisplayGroup -like "Windows Remote Management*" -and $_.Profile -like "*Private*"} | Set-NetFirewallRule -RemoteAddress 192.168.1.0/24

Using Server Manager, install AD DS

Power shell to list of VM hard drives sizes

   1 $vms = Get-SCVirtualDiskDrive -all
   2 foreach ($v in $vms)
   3 {
   4     $d = $v | select -ExpandProperty VirtualHardDisk
   5     Write-Output "$($v.Name), $($d.Size)"
   6 }

List the amount of memory used by virtual machines

   1 Get-SCVirtualMachine | ForEach-Object { $size += $_.Memory }

Powershell and Windows Update

Power Shell Scripts to create a NAT network (without DHCP) on Windows 10

   1 New-VMSwitch -SwitchName "CPTE230" -SwitchType Internal
   2 Get-VMSwitch #just for show
   3 Get-NetAdapter #get the ifIndex of your vEthernet adapter e.g. 67
   4 New-NetIPAddress -IPAddress 192.168.1.1 -PrefixLength 24 -InterfaceIndex 67 #Using the network ifIndex found above, e.g. 67
   5 New-NetNat -Name CPTE230NAT -InternalIPInterfaceAddressPrefix 192.168.1.0/24 #create the NAT
