PS - Hardware Inventory

Amend and run the following script to collect hardware information based on computers configured within an OU:


# Before Running the following is required:
# Directory path C:\temp\inventory must exist or the script needs to be altered to the path of your liking
# LDAP path to the container(s) in AD where the computers you'd like to inventory reside need to be updated in the script
# RPC service has to be running

# Portion of script where it gathers computer names from Active Directory to inventory
cls

# Place the LDAP path to the container in AD that holds your computers.Script will not work until your info is added.

# If you have more than two containers just copy the following and change the $2 to $3.
