Hi Pamela Smith,
Do you use Active Directory in your newtwork. If yes,
You can use two methods to restore deleted user accounts, computer
accounts, and security groups. These objects are known collectively as
security principals. In both methods, you authoritatively restore the
deleted objects, and then you restore group membership information for the
deleted security principals. When you restore a deleted object, you must
restore the former values of the member and memberOf attributes in the
affected security principal. The two methods are:
Method 1: Restore the deleted user accounts, and then add the restored
users back to their groups
Method 2: Authoritatively restore the deleted user accounts and the deleted
users' security groups two times
Method 1 provides a better experience for domain users and administrators
because it preserves the additions to security groups that were made
between the time of the last system state backup and the time the deletion
occurred. In method 2, instead of making individual adjustments to security
principals, you roll back security group memberships to their state at the
time of the last backup.
If you do not have a valid backup of the system state, and the domain where
the deletion occurred contains Windows Server 2003-based domain
controllers, you can manually or programmatically recover the deleted
objects. You can also use the Repadmin utility to determine when and where
a user was deleted.
Most large-scale deletions are accidental. Microsoft recommends that you
take several steps to prevent others from deleting objects in bulk.
