PXE -E53 No bootfile received

[Alstar]

My WDS was working perfectly fine but all of a sudden after I installed
Symantic endpoint protection it broke.
Now it can be a co-incidence or maybe not, i have un-installed symantic btw.

Whenever I press F12 and try PXE BOOT i get this error
PXE -E53 No boot file received

I configured DHCP option 60,66,67
Machine are on same subnet
Tested with Firewall disbled
DisableRogueDHCP reg jey enabled...

I have done a lot of stuff actually still no go from what I have read the
E53 error means that the client was offered an IP but the boot file was not
located..

I tried changing the boot file from boot\x64\pxeboot.com to
boot\x64\pxeboot.n12

Still no luck..

Any ideas guys
