Event ID - 4738



This event generates every time user object is changed.

This event generates on domain controllers, member servers, and workstations.

For each change, a separate 4738 event will be generated.

You might see this event without any changes inside, that is, where all Changed Attributes apear as “-“. This usually happens when a change is made to an attribute that is not listed in the event. In this case there is no way to determine which attribute was changed. For example, if the discretionary access control list (DACL) is changed, a 4738 event will generate, but all attributes will be “-“.
