MAC Address Changes are Not Retained After VM Recovery

Valid on Windows platforms and VMware VM

Symptom

The MAC addresses of virtual machines are not retained after recovering virtual machines.

Solution

MAC addresses are not retained during recovery, to prevent duplicates. To retain MAC address information, set the following registry key on the proxy server: 

Location: HKEY_LOCAL_MACHINE\SOFTWARE\Arcserve\Unified Data Protection\Engine
Key Name: RetainMACForVDDK
Value Type: String
Key Value: 1

On virtual machines with two NIC cards, set the RetainMACForVDDK registry key if you wish to set one as Manual. Otherwise, all cards are set to Automatic after recovery.
