I heart dnscmd

"Hey Laura, I've got this list of 500 A records in our internal DNS that need to be deleted. I know it's a pain, but can you take care of it?"

C:\LauraTools>for /f %h in (a.txt) do dnscmd <DNS Server Name> /RecordDelete <DNS Zone Name> %h A

"Uh, sure boss, what do you need me to do with the other 8 hours and 59 minutes that I'm here today?"

(As an aside, it is the simple genius of the "for-do" loop that leaves me under-motivated to adopt Powershell, as I'm hard-pressed to believe that there's a more elegant way out there to perform the above task.)

For your reference in PowerShell you would do it like this :

$server = 'DNS Server Name'
$zone = 'DNS Zone Name'

get-content a.txt | foreach {dnscmd $server /RecordDelete "$zone $_ A"}

# With use of aliases

gc a.txt |% {dnscmd $server /RecordDelete "$zone $_ A"}
