I have an AD: drive, which should allow me to browse active directory from within Powershell. But when I try to use it, it will not let me navigate beyond the root. From what I have read the given commands should work, but they are failing.

PS AD:\> ls

Name                 ObjectClass          DistinguishedName
----                 -----------          -----------------

Schema               dMD                  CN=Schema,CN=Configuration,DC=company,DC=com

DomainDnsZones       domainDNS            DC=DomainDnsZones,DC=company,DC=com
