x.x.4.x clients need to talk to another system. It is working now after I configure the default route setting at the Cisco switch.

You call 2 a switch ... you would never configure a switch as the default gateway. My guess therefore is that you have a hybrid with a routing module installed in your 3750. You haven't explained if your x.x.4.x clients need to talk to any system other than your server #3. Since your switch appears to be a router, it needs to know how to reach the 'rest of the world' and in particular. So if it is routing, it will need either a default route using NISTNet x.x.4.1 as the gateway OR an explict route for x.x.5.0/24 to the NISTNet box. An alternative is to disable routing functions is the switch and make the NISTNet x.x.4.1 the default GW for your #1 clients. You also need to enable ip_forwarding and define a route(s) in the NISTNet system to deliver traffic between the interfaces. With no changes, can you ping x.x.4.1? >From NISTNet can you ping your server? from your #1 clients, can you ping x.x.5.1?
