Select Menu → Automation → Server Tasks to open the Server Tasks Builder.
Click Edit in the Actions column for one of the following preconfigured server tasks.
Duplicate Agent GUID - Clear error count
Duplicate Agent GUID - Remove systems that potentially use the same GUID
On the Description page, select Enabled, then click:
Save — Enable the server task and run it from the Server Task page.
Next — Schedule the server task to run at a specific time and perform the task.
This clears the error count and removes any systems with the same GUID, and assigns the systems a new GUID.
