Having issues configuring DHCP

[NiKiZe]

Not seeing any images... however my guess is that the TFTP server does not allow the original PXE boot agent to access the file you want to fetch. Try to enable the windows tftp server logs and see what it says, there is also some setting in registry that needs a change to allow for alteranative paths to be used maybe http://ipxe.org/appnote/chainload_wds can give you some hints.
