This is Dresden`s new site.
Some Powershell tips:
1. It is wrong . You won`t find anything
$obj = new-object DirectoryServices.DirectorySearcher("LDAP://CN=Schema,CN=Configuration,DC=DOMNT")
2. It is OK
$obj = new-object DirectoryServices.DirectorySearcher([adsi] "LDAP://CN=Schema,CN=Configuration,DC=DOMNT")
