Use to find out if a host or device is up/reachable before starting applications. I use this script in Windows autostart, but I only want to launch applications if I know that my company network is reachable (run shell:startup in Windows and place a batch file there that tells PowerShell to run the script at logon: ‘C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -file C:\scripts\if_host_is_up_do.ps1’):

	#****
	# WWW
	#****

	$tryGoogleDNS = Test-NetConnection -ComputerName 8.8.8.8

	while ($tryGoogleDNS.PingSucceeded -ne "True") {
	Start-Sleep 5
	$tryGoogleDNS = Test-NetConnection -ComputerName 8.8.8.8
	}

	#*****
	# HOME
	#*****

	$tryHome = Test-NetConnection -ComputerName 192.168.111.1

	#Start app if connection is true, but stop if already running
	if ($tryHome.PingSucceeded -eq "True") {
	$testApp = Get-Process \| Where-Object {$_.ProcessName -eq "caffeine"}
	if ($testApp) {
	Write-Host 'Caffeine already running!'
	}
	else {
	Start-Process 'C:\Program Files\caffeine.exe' -ArgumentList '240 -Key:7' #You can modify the key pressed by converting these HEX values to decimal, https://learn.microsoft.com/da-dk/windows/win32/inputdev/virtual-key-codes?redirectedfrom=MSDN

	$tryWork = Test-NetConnection -ComputerName yourDevice.domain.com

	#Try connection to work server, if not true, wait for active VPN connection, sleep 5 seconds and try again

Use to export and import Windows NPS server configuration. Run every, e.g. 1 hour, to have 2 servers with same NPS configuration:

	#Export configuration on remote server named importServer1 and save to local server share
	Invoke-Command -ComputerName dc -ScriptBlock { Export-NpsConfiguration -Path \\importServer1\c$\ITOps\nps_conf.xml }
	#Import configuration on local server
	Import-NpsConfiguration -Path C:\ITOps\nps_conf.xml

	function Get-DeduppingState {
	$dedupstate = Get-DedupJob
	Do {
	Write-Host "Dedup job still running. Progress is"$dedupstate.Progress"percent finished."
	Start-Sleep 60
	$dedupstate = Get-DedupJob
	} While ($dedupstate.State -ne $null)
	}

	robocopy \\fileshare.int.domain.com\share1\ d:\share1\ /MIR /SEC /R:1 /W:5 /MT
	Start-DedupJob -Volume "D:" -Type Optimization -Memory 90

Use script to modify all user profile shares with new server name and new folder name:

Use script to check if HyperV virtual machines are not running. If any are not running, then send warning mail and start them. Check again after 3 minutes and send a new status mail:

	$From = "hypervisor@domain.com"
	$To = "ak@domain.com"
	$SMTPServer = "monitor.domain.com"

	$offlineVMs = Get-VM \| Where-Object {$_.State -NE "Running"}

	$bodyString = Out-String -InputObject $body
	Send-MailMessage -From $From -to $To -Subject "VMs are not running! New update in 3 minutes!" -Body $bodyString -SmtpServer $SMTPServer
	Start-VM -Name *
	Start-Sleep 180
