How to PXE boot in remote site

Question

The clients in the main site can PXE boot and install OS correctly. However, the clients in remote site are unable to PXE boot. I have tried to enable the DHCP options below, it doesn't work.

66 > PXE Boot Server IP address

67 > SMSBoot\x64\Wdsnbp.com

What's the next step to try? Please share your advice and comments.

Hi,

Thanks for posting in Microsoft MECM Q&A forum.

1,The recommended and supported method for PXE booting client computers on remote subnets is to use IP Helpers. Do not use DHCP options 60,66 and 67 on your DHCP servers. If the options are configured, the DHCP server will masquerade as a PXE server and respond to the client with path to the network boot program, then the PXE will failed. Useful articles for your reference:

PXE clients computers do not start when you configure the Dynamic Host Configuration Protocol server to use options 60, 66, 67

You want to PXE Boot? Don't use DHCP Options.

2,In an environment where there are multiple PXE servers, each PXE server will only reply to the clients that it cares about. Each PXE server should have an entry in the IP helper tables.

The configuration is like this:

IP helper-address <IP address of DHCP server>

IP helper-address <IP address of PXE server>

IP forward-protocol UDP 4011

Refer to: IP Helper-Address Configuration for PXE Boot

Thanks for your time. Have a nice day!

Best regards,

Simon
