Answer: This issue occurs when there are duplicate MAC addresses, which are typically observed with virtual devices that may have
MAC addresses that contain only 16 zeroes.
To resolve this issue:
1. Ensure that you are logged in to the operating system with administrative privileges.
NOTE: Ensure that you create a backup copy of the dconfig.ini file before you make any changes.
2. Open the dconfig.ini file available at SysMgt\Essentials\configuration.
3. Edit the PRIVATE_MAC_EXCLUDE_LIST line as follows:
PRIVATE_MAC_EXCLUDE_LIST=127.0.0.1,0.0.0.0,005345000000,33506F453030,505054503030,0000FFFFFFFF,

4. Save the dconfig.ini file, and restart the OpenManage Essentials services.
