Cant ping router from clients?

[Henco]

Cant ping router from clients but can from server. server has 2 network cards in 2 ranges (same subnet)

NIC config on server:
1. IP 192.168.150.2
SUB 255.255.255.0
DG 192.168.150.3 (want it to be 192.168.200.2 - is it possible)
DNS1 192.168.150.2
DNS2 192.168.200.2

2. IP 192.168.200.2
SUB 255.255.255.0
DG 192.168.200.3
DNS1 192.168.200.2
DNS2 192.168.150.2


On server I have full access to internet with this config but client getting the following dhcp doesnt:

IP 192.168.150.X
SUB 255.255.255.0
DG 192.168.150.2
DNS1 192.168.150.2
DNS2 192.168.200.2


This must be a routing issue and I though I did set up correct static routes but obviously not?
DNS forwarders point to our ISP. [W2K8R2]


PLEASE HELP!!!! (AND THANK YOU!!!!!)
Thanks Harry!

To explain a bit better, x.x.x.2 is server (w2k8r2) and x.x.x.3 is router. I completely understand what you are saying which is why I cant understand why they cant connect as this is the way it IS set up?

THANKS!

The default gateway should be your routers IP address. Your clients DG should be 192.168.150.3, not .2. And if the machine at 192.168.200.2 is a router and a DNS server, then go for it, otherwise, no.
