Hi
If auditing is enable you can track the same by checking the event log.In order to find out changes, creation or deletion events, you must keep the Account Management auditing enabled..You cal also use repadmin
/showobjmeta to trace the same.

Apart from the auditing, you can use third party tools like Quest and Ntewrix to find out WHO changed WHAT, WHEN, and WHERE to list additions, deletions, and modifications made to Active Directory users, groups, computers, OUs, group memberships.
Please mark this as answer if it helps you
If auditing was enabled then yes. You can track the events in event viewer as long as they were not removed.
Tracking changes in AD is usually a difficult task if you do not using third party Tools to monitor changes. The one I usually recommend is Lepide Auditor Suite for Active Directory: http://www.lepide.com/lepideauditor/active-directory.html
