Default Active Directory path when searching for printers
User Configuration\Administrative Templates\Control Panel\Printers
Specifies the Active Directory location where searches for printers begin.
The Add Printer wizard gives users the option of searching Active Directory for a shared printer. If you enable this policy, these searches begin at the location you specify in the Default Active Directory path box.
If you disable this policy or do not configure it, searches begin at the root of Active Directory.
This policy only provides a starting point for Active Directory searches for printers. It does not restrict user searches through the Active Directory.
