Re: Cannot chain load gPXE to Windows 2003 DHCP

I compiled (in ubuntu live boot environment) the 0.9.7 to undionly.kpxe - copied to my TFTP server - also tried the most current build - neither even boot up or chainload.  Tested the rom-o-matic .pxe - and that did nothing as well.  There has to be something blocking the chaining in the 2003 windows server setup.  My TFTP server I moved back to my RIS server hoping by keeping PXE & TFTP on the same - it would help...but alas, nothing still.

Would teamed NICS on the servers cause issue?  I would not think it would...but I am fishing now.  I have not rebooted the DHCP server - but I have restarted the service.

Stumped....

Michael - yes, was trying to load Win7 direct to iSCSI target.   I made the isci_boot.gpxe script, saved it as a unix file and also turned off 2 possible conflicting DHCP devices on my network (hava video streaming box) and for some reason - it is still not chaining the gPXE to the laptop.  It loads PXE then once it gets all the DHCP info that PXE shows on connection, it unloads then just boots up to Windows XP on the laptop - not even getting the gPXE file.

To add how my setup looks...I have tftp running on a Win2003 web server VM, my Win2003 RIS/PXE server runs on a second physical server and my DHCP is on a third physical server.   In my DHCP scope - I had originally 066 pointing to my RIS/PXE server then in my Reservations for this gPXE laptop - I overwrote a new 066 option to point to my TFTP server this holds the undionly.kpxe & script.   I also tried to change my server option 066 to the same TFTP gPXE server thinking PXE boot was going to my RIS server and getting lost - but that did not make any difference.

Any clues on why this is not chaining?  

Ron

Your description of what you are trying to achieve is quite unclear, but I am 
guessing that you are trying to install Windows 7 directly to an iSCSI 
target.  If this is not correct, then these instructions will not work for 
you.

Place undionly.kpxe on your Windows Server 2003 TFTP server (which you have 
already done).

Configure your Windows Server 2003 DHCP server with option 067 Bootfile Name 
as "undionly.kpxe".  Define a new user class called "gPXE" as shown at 
http://etherboot.org/wiki/pxechaining.  Configure option 067 for the gPXE 
user class as "iscsi_install.gpxe".

Create a file "iscsi_install.gpxe" containing

  #!gpxe
  set keep-san 1
  sanboot ${root-path}

and place this "iscsi_install.gpxe" file on your Windows Server 2003 TFTP 
server alongside undionly.kpxe.

Create a DHCP reservation for the machine you are trying to boot via gPXE, and 
configure option 017 Root Path as "iscsi:X.X.X.X::::iqn.XXXX-XX.xxx.xxxx.xxx" 
where "X.X.X.X" is the IP address or DNS name of your iSCSI target, 
and "iqn.XXXX-XX.xxx.xxxx.xxx" is the iSCSI IQN that you want to install to.
