Windows 8/Server 2012

[hech]

Hi,

I'm going to setting up a diskless and headless computing cluster. (no monitor, keyboard, mouse)

Right now I'm in testing phase, here's my setup:
1 Win Server 2012 with MSDHCP, IIS 8, iSCSI Target and a TFTP server for undionly.
1 Diskless Node with display so I can monitor progress
1 Diskless Headless Node
Gigabit LAN
WinPE4

Windows Server Unattended Installation finishes then boots to OS at first, then I shut it down.

This is where my problems start: I turn it back on, it loads for a long time then fails, it restarts automatically then boots to Windows fine.

This is my real problem: When the boot fails and it restarts, its MAC address are all zeros. When it has its original MAC address it does NOT boot, when it restarts with the MAC address 00 00 00 00 00 that is when it boots to windows.

PS: I will be using differencing VHD's with this, one child VHD per node.

I know nothing about PHP, dynamic scripts, and databases so I used this simple script I made:

Code:

!ipxe

:retry
dhcp net0 || goto retry
set initiator-iqn computenode
set arch amd64
set keep-san 1
sanboot --drive 0x80 iscsi:${root-path}::::${mac} ||
module amd64/media/bootmgr                     bootmgr        ||
module amd64/media/Boot/BCD                    BCD        ||
module amd64/media/Boot/Fonts/segmono_boot.ttf segmono_boot.ttf    ||
module amd64/media/Boot/Fonts/segoe_slboot.ttf segoe_slboot.ttf    ||
module amd64/media/Boot/Fonts/wgl4_boot.ttf    wgl4_boot.ttf    ||
module amd64/media/Boot/boot.sdi               boot.sdi        ||
module amd64/media/sources/boot.wim            boot.wim        ||
chain wimboot || reboot

Any help would be greatly appreciated.
