Help with multi-homed, multi-subnet windows server and client access

I have a Win2K8 server with two NIC's.  I'd like clients to be able to access services from two IP's (one public, one private).  I'd like clients to be able to hit either IP when connected locally.  Is this possible?  What routing/IP tables on the server are necessary?  

Current IP:  17.17.17.17/24
Gateway: 17.17.17.1

Additional IP: 10.10.10.10/24
Gateway: 10.10.10.1

Clients: 10.10.20.0/24, 17.17.18.0/24, and any other routable internet address

Currently the windows server NIC's are set to:

NIC1:
IP:        17.17.17.17
MASK:  255.255.255.0
GW:     17.17.17.1
DNS:    Our DNS Servers

NIC2:
IP:        10.10.10.10
MASK:  255.255.255.0
GW:     NOT SET - Multiple gateways not allowed
DNS:    NOT SET

Clients can hit 17.17.17.17, but not 10.10.10.10, because I'm not sure how to add a route to 10.10.10.10.

More specifically, I'm not sure how to add a route to 10.10.10.10, without interrupting access to the 17.17.17.17 IP.

I am thinking if they can hit 17.17.17.17 maybe:

route add -p 10.10.10.0 mask 255.255.255.0 17.17.17.17

Manually adding static routes to each of the subnets we needed to get to worked.
