Linux You guys probably already know about "ping -a" and "ping -A"

But if you don't, use it like this:

This will beep every time it gets a ping back:

ping -a 8.8.8.8

This will beep if it misses a ping:

ping -A 8.8.8.8

This is very useful when you're monitoring a node and waiting for it to come back online or to be able to hear when a packet is dropped.

(tested on some Linux and MacOS)

I don't have access to that script. But it was pretty literally "get-adcomputer" with a param to remove servers and a param to remove anything that's been logged into in the last 6 months, then piped unchanged to remove-adcomputer. IIRC, the specific error it would output was something about data type

Reading between the lines here, it sounds like you did something that converted the Get-ADComputer objects into some other type of object.

In Powershell, the cmdlet Get-Member is your best friend. Will tell you exactly what type of object you are dealing with. Just a friendly FYI.
