If you have Cisco switches, the relay can be accomplished with the command "IP HELPER-ADDRESS " in each of your vlan statements

You've got some answers. Yes, your switch does probably have IP helper addresses. You would enter the address of the DHCP server for all VLANs. But, in Win03 DHCP, you will also need to add scope statements for all those VLANs. One of the more important, and unique to each VLAN, of scope additions would be the IP gateway, e.g. the router port serving that VLAN segment. There's others. Though about what happens if that server dies yet?

Hi..
Yes you can do that by creating different scopes in DHCP server with gateway's as the VLAN's IP.

We have done similary in our network & it is working fine.
