The answer in short: UDP-Cast wasn't resonsible for that!

It has been an behavior of the the harddiskprotection "HDD Sheriff" witch 
protects the bios also. So a cloned target system will have a cloned 
Bios.Backup of the source also. This rewrites then the "changed" mac of 
the nic of the target after rebooting. 

I've received an MAC-writing tool from the Nic-producer- with that the 
strange error could be located quickly.

I'm sorry for that. But still thankfull, becaus of your guidance, which 
gave me some ideas to the problem... ;-)

yours sincerely
