Hi and thanks,
Yup, already seen that one. Looks like my router(s) don't have a SHCP option 66, but that's not my problem on the mainlocation. There it doesn't work at all.
I could work with DHCP from the server, however I don't think that would bring me much benefit, since that also would not work for the sub-locations, only for main. There are only servers on the main location.
I mainly want to focus to get the locally provisioning to work, because when that works, I can do the other location "manually" through chancing the PnP server. That also does not work now. because of the errors "Did not write..."
