Can't ping fax server from some addresses

I'll keep it basic since this is a basic routing/firewall issue from what I can tell. Thanks in advance for the help!

I have a network on 10.0.0.x

The domain controller at 10.0.0.2 can ping the fax server at 10.30.0.10

A user PC at 10.0.0.123 CAN'T ping the fax server.

When I took over this network, someone loosely mentioned that higher numbered IP addresses are blocked from pinging/talking/traffic/etc on the 10.30 network. I can't find what is blocking that or if that is even true though.

How do I find out if the higher range addresses like .123 are being blocked from talking on the 10.30.x.x network?
What am I missing?

Check your running config of the firewall / router, since the server can ping the 10.30 network but the workstation cant most likely a acl on the router/fw that isn't configured to allow the .123 address to ping. Could also be that the server has both networks configured in its NIC is the reason that it can access both subnets.  I would also verify the subnet mask of the systems a 255.0.0.0 on the server would include both .0 and .30 whereas 255.255.XXX.XXXX would not.  Hard to really say since you didn't describe the physical layout.  How is the fax connected to the network in relation to A: server and B: workstation.
