My iPXE or gPXE does not read my script file on my iscsi target server (Windows Server 2012 R2)

[mezta21]

Hi good people,

I'm trying to install windows 7 into an ISCSI SAN Target on Windows Server 2012 R2, I've already configured my DHCP and TFTP Server by following this video tutorial "

https://www.youtube.com/results?search_query=hyper+v:+windows+installation+on+iscsi

" but unfortunately it didn't work like what I'm expecting, so kindly please check the attached image from the ipxe boot up process and tell me what might be the problem why my Client1.txt command script file is not working, and also why i'm getting this type of error message.
TXE: 1 x "Network Unreachable (

http://ipxe.org/28086011)"

Here is are the commands inside my Client1.txt script file:

#!ipxe

dhcp net0
set root-path iscsi:192.168.1.1::::iqn.1991-05.com.microsoft:server1-Client1-target
set keep-san 1
sanboot ${root-path}


--Thank you,
