Using Vristual Server 2003 R2 on a 2003 Ent Server. One program I run uses the MAC address for licensing. Twice I have had to Remove and Recreate to VM, and each time the MAC changes, requiring me to have to request a new license key. If I have to do this again, for for other VM, how can I control the MAC address to be assigned? ANd can you point me to an article on how MAC are assigned fro VMs? Thanks.
