Here's an example of how to list all servers in an organization through an LDAP filter where the search is performed on any OU that matches the search term and also belong to the OU = Domain Controllers, sorted by name and displaying only the name and the Distinguished Name.

Thanks Albert Fortes for their assistance.

get-qadcomputer-Ldapfilter NT)))))) "| Where {($ _.DN-like '* OU = The ye ye *')-or ($ _.DN-like '* OU = Domain Controllers *')} | sort Name | select Name, DN

Here are the results:


We can also query the computers within a specific OU

get-qadcomputer-dudip 0-lf-sl "(objectclass = computer)" | where {($ _.DN-like '* OU = Whatever you like *')} | select DN

Another query might be the following which would get a file listing all computers in an OU in Active Directory that contains the word loquequeráis

get-qadcomputer-dudip 0-lf-sl "(objectclass = computer)" |? {$ _.DN-like "* OU = loquequeráis *"} | export-csv-notype-Encoding default "C: \ computerlist.csv "

I hope it been usefull.

See you soon.
