my wds server is on network segment 192.168.200.0/24 where there's not dhcp server. in second segment (192.168.0.0/24) is dhcp server, Domain controller and workstations on them have to install win 7. i configured mikrotik dhcp server with option 66 = 192.168.200.28 option 67 = boot\x86\pxeboot.n12. on cisco router that is between 192.168.0.0/24 and 192.168.200.0/24 i set ip helper-addres on interface that is in segment 192.168.0.0/24. on wds is disabled firewall, there's not antivirus program.
i tested, i installed dhcp server,secondary DC in segment 192.168.200.0/24 i booted workstation in network segment where is wds and process installation is ok. wds works ok.
when i boot workstation over network i receive
pxe-e32: tftp open timeout
where's i made mistake?
