Steps to reproduce:

  1. Install an AD LDS instance on Windows Server 2012.
  2. Create a partition, e.g. CN=MyPartition.
  3. Install one of the following updates: KB3156416 orKB3160352.
  4. Create20 containers in the root of your partition.
  5. Run the following PowerShell script:
$port = 389
$computerName = "computer.domain.com"

$strFilter = "(&(objectCategory=Container)(|(showInAdvancedViewOnly=FALSE)(showInAdvancedViewOnly=TRUE)))"

$searchRoot = New-Object System.DirectoryServices.DirectoryEntry "LDAP://$computerName`:$port/CN=MyPartition"

$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = $searchRoot
$objSearcher.Filter = $strFilter
$objSearcher.SearchScope = "Subtree"

try
{
    $results = $objSearcher.FindAll()

    foreach ($objResult in $results)
    {
        $objResult.Path
    }
}
finally
{
    if ($objSearcher) { $objSearcher.Dispose() }
}

RESULT: None, i.e. the search will not return any results (though it should). Also, you will get the following exception:

System.DirectoryServices.Protocols.DirectoryOperationException: An operation error occurred.

If there are less than 20 containers or if you specify a page size for theDirectorySearcher interface, the script will return your containers.

Uninstalling KBs mentioned on step 3 will fix the issue. Also, the same KBsdo not cause the  issue on other operating systems (we've checked on Windows Server 2012r2, 2008r2, 7, 8, 8.1 and 10).
