Staying up-to-date with Windows Server updates for Remote Desktop Services (RDS)

Microsoft Remote Desktop Team get customer enquiries asking which RDS updates are available for a particular Windows Server platform; or when providing support we need to verify if certain hotfixes and servicing rollups are installed on the customers’ servers. To make it easier for customers and ourselves, we regularly revise KB articles that list all of the available updates specific to Remote Desktop services for each Windows Server release:

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
