Don’t use DHCP Option 60/66/67 when you want to use UEFI & Legacy PXE Boot with MDT

If you want to use EUFI Boot with MDT 2013 Update X.
Don’t use DHCP Option 60/66/67!!!

DC01 = Windows Server 2008 R2 SP1
DC02 = Windows Server 2012
MDT01 = Windows Server 2012 R2

UEFI Client: Dell Laptop E5450
BIOS Client: HyperV Virtual machine with Legacy network adapert

DC1; MDT01 and DHCPServer all in Subnet1.
(IP Helper is set for DHCPServer for DHCP and for DC01 & MDT01 for DHCP and BootP – I checked serveral times if everything is right here)
UEFI Client and BIOS Client in Subnet2.

Situation1 — Using no DHCP Options and WDS running (IP HELPER-ADDRESS):
UEFI Client – Boots perfectly (contacting Server MDT01)
BIOS Client – Boots perfectly (contacting Server MDT01)

Situaion2 — Using no DHCP Options and WDS just running on MDT01:
UEFI Client – Does not boot (no error information is provided)
BIOS Client – Does not boot (no Bootfilename recieved)

Situation3 — Using DHCP Options(Option 66=”IP of MDT01″ Option 67=”\x86\wdsnbp.com”) and WDS just running on MDT01:
UEFI Client – Does not boot (no error information is provided)
BIOS Client – Boots perfectly (contacting Server DP1)

Situation4 — Using DHCP Options(Option 60=”PXEClient” Option 66=”IP of MDT01″ Option 67=”\x86\wdsnbp.com”) and WDS just running on MDT01:
UEFI Client – Boots perfectly (contacting Server DP1)
BIOS Client – Does not boot (taking hours to recieve dhcp options..)

Solution:

On most switches you can configure ip helper-addresses. This is most time al ready configured for the use of DHCP.

Add the IP of the MDT server als ip helper-address:

Example:

interface Vlan100
description GEBRUIKERS VLAN
ip address 192.168.101.254 255.255.254.0 show
ip helper-address 192.168.25.6   (DC01)
ip helper-address 192.168.25.7   (DC02)
ip helper-address 192.168.25.30 (MDT01)
end
