Static route works on one computer, not the other

I have been struggling with this for a couple days now, maybe I just need some people with a fresh perspective to figure out what the issue is.

Basically I have a bunch of computers that are being routed through a specific gateway in order to access a web page that is hosted internally on a separate subnet. I set up static routes on all of the computers, and they all work... except one.

Here's what a route print -4 looks like for a working computer (Windows 7):

And here's a route print -4 from the station that doesn't work (also Windows 7):

      10.zzz.zzz.0    255.255.255.0   10.xxx.xxx.147       1
===========================================================================

Both of these stations are running Windows 7.

So essentially what I am trying to do here is route all traffic to the 10.zzz.zzz.0 subnet through the 10.xxx.xxx.147 gateway. Everything else should go through the 10.xxx.xxx.230 gateway. This is the intended behavior, and again it is working everywhere but that one station. I noticed that the Active Route metric costs differ between the two stations, but I am new to the routing table and I am not sure how that is impacting the behavior.

I hope I have been able to explain the situation clearly. Any help would be much appreciated. I can provide any additional information if needed!
