@snap7B Any news on your test using the netdom command? Unfortunately I don’t have such an AD setup and won’t find the time to set one up any time soon. But I could try adding more debug output and provide that as a new DLL to you so we can figure out what goes wrong.

Thank you. yes, you are right the problem is NOT the “//” but SPT on the switch that caused “udhcpc failed”. the solution is posted here:

Tested imaging with a dumb switch, and everything worked.

I am actually imaging a bunch of 7040’s. My test deployment went well, but I am also on Trunk. I updated from 7565 to 7671 yesterday, and other than a small installation snafu, it has worked perfectly.
