I don’t know if you found a solution to this but after goggling the problem for days and days. I thought to myself what could have changed between .32 and 1.2. So I looked at the boot setting in the DHCP server and saw that the file name had changed from .32 to 1.2 so make sure you check DHCP settings edit option 067. I really hope this helps someone else bc it drove me nuts. I wish that someone would big red flags and fireworks going off anything to draw more attention to the change in the file name.
