CONFIGURE DHCP IN CISCO ROUTER FOR PXE CLIENT WITH WDS SERVER

[FS35527]

good day
I have a project in which the computers can boot from the NIC to install the operating system, I have a WDS server mounted on Microsoft Server 2016, which also has the role as a TFTP server working correctly, the dhcp is delivered by the cisco router, The ip delivers it but it gives me the error of ""NBP is too big to fit in free base memory"", then I indicate the configuration.

ip dhcp pool LAN
network 192.168.15.0 255.255.255.0
bootfile \Boot\x64\Images\boot.wim
default-router 192.168.15.1
dns-server 172.16.1.244 

interface GigabitEthernet0/1.88
description SERVER
encapsulation dot1Q 88
ip address 172.16.1.1 255.255.255.0
end

interface GigabitEthernet0/1.15
description LAN
encapsulation dot1Q 15
ip address 192.168.15.1 255.255.255.0
ip helper-address 172.16.1.244
end

I already tried configuring option 60, 66, 150, 67 specifying the ip and in asci mode the boot path but I have not had success.

thnks

option 66 ip 172.16.1.244   <<- this is server bootp file host ?
option 67 ascii "\Boot\x64\Images\boot.wim"
default-router 192.168.15.1
dns-server 172.16.1.244
netbios-name-server x.x.x.x
netbios-node-type h-node

ip address 192.168.15.1 255.255.255.0
no ip helper-address 172.16.1.244    <<- DHCP helper should be dhcp server, since you are in same network you do not need help address
end
