Cannot see all networked PC's

Hi,

I have a 2008 R2 Server with 2 active NIC's. One connect to a public network 192.168.1.3. The 2nd NIC is connected to the work network with 10.95.10.1. In network places the server see's PC's from both network segment, but does not see all of them. Another PC that manages the public pc reservations and is connected the same way can see all 25 PC's.

My questions is how do I get the server to see all 25 PC's/
