ActiveDirectory Error 0x8000500c with Bypass Properties

Question

I got the following code snippet ( SomeName/ SomeDomaincontains real values ​​in my code)

var entry = new DirectoryEntry("LDAP://CN=SomeName,OU=All Groups,dc=SomeDomain,dc=com");
foreach (object property in entry.Properties)
{
    Console.WriteLine(property);
}

It prints OK for the first 21 properties, but with an error:

COMException {"Unknown error (0x8000500c)"}
   at System.DirectoryServices.PropertyValueCollection.PopulateList()
   at System.DirectoryServices.PropertyValueCollection..ctor(DirectoryEntry entry, String propertyName)
   at System.DirectoryServices.PropertyCollection.PropertyEnumerator.get_Entry()
   at System.DirectoryServices.PropertyCollection.PropertyEnumerator.get_Current()
   at ActiveDirectory.Tests.IntegrationTests.ObjectFactoryTests.TestMethod1() in MyTests.cs:line 22

Why? How can I prevent this?

Update

This is a non-standard attribute that does not work.

I tried using entry.RefreshCache()and entry.RefreshCache(new[]{"theAttributeName"})before listing the properties (which did not help).

Update2

entry.InvokeGet("theAttributeName")works (and without RefreshCache).

Can someone explain why?

Update3

It works if I put the FQDN for the item: LDAP://srv00014.ssab.com/CN=SomeName,xxxx

Bounty

I am looking for an answer that relates to the following:

• Why entry.Properties["customAttributeName"]does not work with the specified exception
• Why entry.InvokeGet("customAttributeName")does it work
• Reason for exclusion
• How to get both workers
