Very Simple Powershell Ping test or IP scanner script

By Tom Kitching

This simple Powershell script will carry out a quick check against each IP in a 24 bit subnet and return a value of true or false dependent on whether or not it receives a reply. It’s similar to using an IP scanner or a ping script.

[cc lang="powershell"]$subnet = "10.20.6."
1..254 | Foreach-Object {write-host "$Subnet$_…" (Test-Connection -ComputerName "$Subnet$_" -Quiet -Count 1 ) }[/cc]

1 2	[cc lang="powershell"]$subnet = "10.20.6." 1..254 \| Foreach-Object {write-host "$Subnet$_…" (Test-Connection -ComputerName "$Subnet$_" -Quiet -Count 1 ) }[/cc]

Set O365 Password to never expire for just one user

Add AD security group to local administrators on Hyper-V server running core

By admin

First connect to the remote server with powershell

[cc lang="powershell"]Enter-PSSession -ComputerName contoso\hv01[/cc]

1	[cc lang="powershell"]Enter-PSSession -ComputerName contoso\hv01[/cc]

Next run the command to add the group:

[cc lang="powershell"]Add-LocalGroupMember -Group "Administrators" -Member "CONTOSO\Hyper-V Admins"[/cc]

1	[cc lang="powershell"]Add-LocalGroupMember -Group "Administrators" -Member "CONTOSO\Hyper-V Admins"[/cc]

If you’re paranoid (like me) and want to check this worked you can use:

[cc lang="powershell"]Get-LocalGroupMember "Administrators"[/cc]

1	[cc lang="powershell"]Get-LocalGroupMember "Administrators"[/cc]
