[ ] For search duplicates IP/DNS name (Author: Sean Ivey ):
#Import the Active Directory Module

#Define an empty array to store computers with duplicate IP address registrations in DNS
$duplicate_comp = @() #Get all computers in the current Active Directory domain along with the IPv4 address
#The IPv4 address is not a property on the computer account so a DNS lookup is performed
#The list of computers is sorted based on IPv4 address and assigned to the variable $comp $comp = get-adcomputer -filter * -properties ipv4address | sort-object -property ipv4address
#For each computer object returned, assign just a sorted list of all

#For each instance in $duplicate_ipv4 and for each instance

I send this information one time at month to Help Desk departamente. I Have this bit change:
