What is Lost and Found Container in Active Directory
In this post, we’ll learn more about Lost and Found container in Active Directory. What is Lost and Found container and what is it’s use? This is favorite question of some interviewers. I’ve observed that many System Administrators don’t have any clue about Lost and found container in Active Directory. Matter of fact is that many Administrators have never heard about this container. L&F container is where objects that are orphaned during Active Directory database replication are stored.

Let’s take a scenario to explain Lost and Found in detail. Assume one Domain named as itingredients.com is extended to two geographical sites i.e. US and UK. Assuming that we have one Domain Controller named DC01 in US and another Domain Controller named DC02 in UK site.
If we create new OU named as OU01 in DC01 then it would replicate to DC02. Now create a Domain User named TU01 in OU01 but before it replicates to DC02, delete the OU01 from DC02. After replication is completed, it would also delete OU01 from DC01.
Now take a pause and answer the question, what would happen to user TU01. Do you think that user TU01 would also be deleted along with OU ? But please remember that when we deleted an OU at that point of time, it was an empty Organizational Unit and it doesn’t contain any user in it.
In this scenario, user TU01 would automatically move to Lost and Found container because now user TU01 is orphaned and it doesn’t have any Organizational Unit as it’s home.
