    This tool looks great...however I have spent the better half of the day attempting to get this going 😞

    When attempting to enable Proxy DHCP, I get the following error:

    Updated Settings Successfully, But Could Not Copy PXE Binaries On One Or More Com Servers. Check The Logs For More Info

    There's nothing else in the logs. I've watched the videos and completely uninstalled/reinstalled.

    Any help would be great thanks!

    Happened to me because of tftp using the files most of the time, because clients on network were in boot loop and nonstop asking for the boot files. Try LockHunter software or sth similar to check if some programs are using the boot files pxeboot.0 and the ones in proxy folder.

    use of tftp using the files mos

    Ok! so I got this to work by turning TFTP off, then updating ProxyDHCP, then reenabling TFTP.

    Now, I can boot legacy systems, but when I attempt to boot UEFI, I get: mstsc_kBaacBtVwW.png

    My router (192.168.99.1) is doing DHCP (with no options), I'm running the DHCP proxy on Theopenem server (192.168.99.251).

    I've double checked my config for the DHCP Proxy and the Next-Server is set to 192.168.99.251.

    🤔

    I'm using ISC DHCP server and I had to create classes for different architectures on that main server, although I have multiple VLANs, not one like you do.
    But obviously the PXE client tries to download boot files from your main DHCP server and even then it tries to download WRONG file, it should be pxeboot.0, and it should be set by the DHCP server to point to correct architecture path on TOEMS, so in case you or someone else needs the config for ISC DHCP, here's mine:

    class "UEFI-32-1" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00006";
        filename "proxy/efi32/pxeboot.0";
}

class "UEFI-32-2" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00002";
        filename "proxy/efi32/pxeboot.0";
}

class "UEFI-64-1" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00007";
        filename "proxy/efi64/pxeboot.0";
}

class "UEFI-64-2" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00008";
        filename "proxy/efi64/pxeboot.0";#
}

class "UEFI-64-3" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00009";
        filename "proxy/efi64/pxeboot.0";
}

class "Legacy" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00000";
        filename "proxy/bios/pxeboot.0";
}
