In our environment it can happen that a Windows computer name changes. Than I have two entries in the ePO the new computer name which has a newer last communication date and the old which has an older last communication date.
How can I delete such multiple entries.
I use ePO 5.3.2 and 5.3.1
Create a query (name SysDup), Mananged Systems, under filter/System Name: Is duplicated and Last Communication: Is not within the last 3 days (or whatever). Save/Run and confirm results.
If results are good, create server task, under actions: run query, choose the Sysdup with sub-action delete systems and a schedule of your choosing (hourly, daily, weekly ...)
