Multi sub net DHCP PXE TFTP Server Resolution

Hello people,
So i have hit a bit of a snag, and here is some basic details please dont hesitate to ask if you need more.

server is a MS Server 2008 r2 64bit Standard,
running DC,DNS,DHCP,IIS,FTS
DHCP - Superscope
x.x.5.5-254
x.x.6.5-254
x.x.7.5-254
x.x.8.5-254

these aswell as the server are already in a VLAN, and as you may already have guessed, anything sat outisde of the x.x.5.x subnet cannot talk to the server, which sits in that subnet…
ive tried adding A records to the DNS to help, but as this is a PXE boot, the DHCP server is handing out IP’s in a subnet that cannot talk to the DHCP server, or the DNS

is this is as simple, as setting up routing on the switch to redirect all traffic on ports from out lying switches from one subnet to another?

switches are,
Netgear M5300-52G
Netgear M5300-28G
(layer 2+)
connected to

Netgear M6100
(layer3)

connected to
Server(s)
Gateway(s)

sorry if this is a stupid question, but i am rather new to this level of networking.

so after a chat with @tylerm we have a solution! or at least, a potential one..

DHCP Relay! (also known as IP Helper) which hopefully, will connect enough of the dots to resolve the issues im having, if not then some routing on top of that should do the trick.

big thanks to @tylerm for helping out, i get to keep my head of hair for at least 1 more day.. hurrah!
