Had a problem with Merak FlexLM application today which cannot be started and complaint about licensing after I P2Ved the server to vSphere4. After when I looked into FlexLM .lic license, found out the license only eligible for the old physical server mac address and cannot be transferred to any other machine. Luckily, after I manually changed guest OS mac address (NIC property) akin to what I found in .lic license, I can start using the application (PEEP) flawlessly. To manually change and use your own mac address, please follow below :
Device Manager -> Network Card Property -> Advance -> Network Address / Local Administered Address -> Value
