UEFI On windows server 2008 R2
The only way I’ve been able to get this to work is to manually set the 067 option for each client that needs it. Packet capture shows that windows server does not appear to respond to the request properly.
Any other thoughts? Im donw to creating a new scope after those settings are in and seeing if that takes hold.

The simple answer is to either upgrade to server 2012 or use linux dhcp server if you want to limit the manual entries. The 2008 dhcp server does not have the proper filters to make the instructions work.
