I acquired these two machines at different times and both were from the grey market. The ³What the ...² is sitting fresh in my mind ... How can this be? In the last 15 years of being in IT, I have never encountered a ³burned-in² duplicated MACs across two physically different machines. What are the odds, that HP would dup¹d them and that both would eventually end up at my shop? Or maybe this type of thing isn¹t big of deal... ?
None of the HP servers I have contain duplicate MAC addresses. (I just looked through all the iLO2 cards to make sure I wasn't lying.) I'll send you some details offlist. ~Seth
