Windows Server 2 NICs - routing problem


Following situation;
1 Server 2008 with 2 NICs.
NIC 1: connected to network: with MASK GW
NIC 2: connected to NAS: with MASK no GW

Generally it works, BUT when I try to ping into the network then the first ping's answer is "destination host unreachable". The second ping already works normal.
(ping to NAS works just fine)

Here is my "route print":

I want the connection to work normally in both direction.
Do I have to add a route?
Thanks for your help,

One of the problems is the overlapping networks. with a mask of (otherwise known as is the same network as

basically with with a you are saying any address on the 10.x.x.x is on the same network so your ping will go out of the wrong interface. You should change the nas network to 192.168.x.x addresses (or something along those lines).
