Results of Reinstalling Windows On Managed Systems With McAfee Agent 5?

Our ePO 5.3.2 system tree syncs with Active Directory.

Can we wipe and reinstall Windows using the same computer name without creating duplicate systems in ePO or having to manually delete the old system before reinstalling Windows?

Our workstations are encrypted with either Drive Encryption 7.1.3 or Management of Native Encryption 4.1.  Will ePO create new encryption recovery keys or reuse the existing recovery keys after reimaging?

Re: Results of Reinstalling Windows On Managed Systems With McAfee Agent 5?

This depends on a few different factors:

1. ePO will re-associate to the same LeafNode ID in the ePO database if the system connects using the same MAC address as the last communication and McAfee Agent does not have a GUID. If the MAC is different a new LeafNodeID will be created and thusly an entry in system tree will be generated.

2. If you enable MDE the Machine key re-use option the previous key will be reused to encrypt the system. If not the system will generate new keys. This option is found in Server Settings | Drive Encryption | Edit

3. If using MNE to manage Bitlocker, Bitlocker will generate new keys.

Note: ePO does not generate either recovery or machine keys for either Bitlocker or MDE; these keys are generated on the client system and uploaded ot ePO. If using machine key resuse, the key is stored on ePO from a previous generation and the system download the key and reuses it.
