I am in the process of setting up VLANs on a switch.... one will be 10.53.x.x and one will be 10.54.x.x.  How do I configure my server to hand out 10.53.x.x addresses on VLAN1 and 10.54.x.x addresses on VLAN2? I have 2 NICs on my server and am running windows server 2003. The server is running DHCP.

You will need to set up DHCP forwarding on your Layer 3 device (router, layer 3 switch) to point to the IP of your DHCP server.  Then, on your DHCP server, you simply define multiple scopes - one for each IP Network from your different vlans, such as 10.53.0.0/16, 10.54.0.0/16, and so on.

This layer 3 device will know what IP's to assign to what VLANs?

No, the layer 3 device will pass along the broadcast, if you configure DHCP forwarding (Cisco calls it IP Helper), to the DHCP Server.  The DHCP server will compare the request with its scopes and assign the appropriate IP address.

alright, that makes perfect sense! right now we have it configured that 4 switches are currently hooked up to a router, which then goes out to the internet. The server is on a switch, along with a computer. Do we configure the router, or the switch for the IP helper?

by configuring the router, it sounds like the server would have to be on the other side of the router, which we cannot do

You would configure it on each interface, in each vlan, on the router.

Yes, yes, and yes.  :)

Most routers or layer 3 switches will automatically route between connected interfaces.  Each vlan will have to have a vlan interface assigned with an IP address which would be the default gateway for that particular vlan.  Then connect the default route in your router to the Internet.
