I want to remove a .dll from workstations in a domain.  Is this possible?

Yes... 99.9% of things are possible with Powershell.


$Computers = Get-Content C:\Computers.txt

$Computers | ForEach-Object{
[string]$FilePath = "\\$_\c$\Path\To\Dll.dll"
$DLLExsists = Test-Path $FilePath
if($DLLExsists -eq $true){Remove-Item $FilePath -Force}
}# ForEach-Obj...

That is the simplest form of a script to do what you ask.

You may want to ping each machine before attempting to do other things to if because the ping timeout is shorter than the error "RPC Server unavailable" and it will reduce error for when you come to a machine that is not on or otherwise unreachable.

Also it is possible to get a list of computer names directly from Active Directory in Powershell. You should be able to search this forum to find examples of this.

Basically, your going to have invest some time into Powershell to get the best results. But.. YES it is possible.

I would use test-connection -quiet -count 1 versus a ping as it will return issues such as "lack of resources" . However the RPC issue might not be caught, I just mention that because I am seeing issues where test-connection works but gwmi fails (still trying to figure out why, in some cases it is a DMZ but other cases I have been told the end point machine has been modified so that RPC uses custom ports).
