DESCRIPTION

Builds a directory searcher object using Get-DomainSearcher, builds a custom LDAP filter based on targeting/filter parameters, and searches for all objects matching the criteria. To only return specific properies, use "-Properties samaccountname,usnchanged,...". By default, all computer objects for the current domain are returned.
