Hi Gerben, thanx for the explanation. That could well be the case. I little bit of an unwanted situation then because those ESX servers are not all the same. When I deploy the same servers (be it ESX or just some Windows servers) I make sure everything is the same, even the placement of cards in PCI slots. Anyways a good thing you ran into this, good to know.

Hi Dennis, Thanks for your response. Your assumption was right, they all have the same hardware amount of nics etc.
I don’t know for sure, but I can imagine that a pci slot order also makes a difference. It may wel be that on the other two the pxe devices are last in row and are not able to load, which is not noticed because they are not used.

Great good-to-know article.Since you were installing 3 servers I assume they all had the same hardware, amount of NIC’s, HBA’s etc. Any idea as to why only one of the servers experienced the problem?
