02/27/2025, 4:33 PMThe PVS servers are also dhcp servers for these subnets. They appear to be handing out addresses to non-streamed VMs fine, but efi pxe boot is timing out

To goal is to move session hosts into 2 different subnets, 1 for app hosts, 1 for desktop hosts, then move the PVSes into a 3rd new subnet for infrastructure. I've added new NICs to the PVS servers in the 2 new session host subnets and the DHCP options for the 2 new session host subnets are the same as what's currently working, adjusted for the new subnet addresses.

02/27/2025, 4:46 PMif you added NICs in the new subnets then you'll need to make sure that the streaming service is bound to those if memory serves me correctly

02/27/2025, 4:47 PMpretty sure this is called "DHCP helper" where you have endpoints that are in a different subnet than the DHCP server

02/27/2025, 4:49 PMheh, I tried to tell the networking guys this, and gave them the documentation for how to do it on our firewalls but they declined

02/27/2025, 4:54 PMI don't think it's a dhcp issue but I'm having trouble confirming that clients the new subnet are receiving all the options. I can only get so much info from the registry
