@george1421 Hi, Thank you for your complete and interesting feedback.
I think you are right, but i cannot be sure yet at 100% because i am not the network guy of my office, and i don’t really have … one. it’s more an external company followed by the network administrator (who never do network jobs), … it’s complicate this day’s.
I should be able to fix that network issue (by the way we have full of Cisco 2950, 3750, etc), but not yet, i don’t have the hand of Cisco switchs.
In the meantime i will follow your tip with a “simple” switch, i tried it this afternoon and it’s working, it maybe will fix my 1st issue with “undionly.kpxe”. I tried to boot a Lenovo M73e in a computers room, and it failed with “no configuration methods”, but with a “simple” switch i was able to boot completly and make an auto registration to FOG Server. I did the same with the Lenovo Laptop and it worked too.
Next week i will try to make images of a windows 7 computers, a Windows 10, import a computers room and deploy somes softwares, i should be ok, the FOG server look good. Just need to anderstand how FOG works
