You must replace those executable files when you restore the ePO server. In the next lesson, you will learn some basic techniques for troubleshooting ePO. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
