ipv4 address 192.168.1.68
ipv4 subnet 255.255.255.0
ipv4 default gateway 192.168.1.1

and my linux server settings are

Could you please describe, how the servers are physically connected to the network? It seems to me, that the only solution is using a router between the subnets, that has two IP addresses (one in each subnet).

If this is an home network, and you don't have enaugh network knowledge, simply choose static ip's in the same subnet, that is all numbers which value in the mask is one, must be the same.
In your case the subnet is 192.168.1.xxx (mask 255.255.255.0), so simply set the address with this 3 numbers changing only the last one.
I.E. If you windows machine has address 192.168.1.68 you can assign to Linux server 192.168.1.128.
Or the reverse: Linux=192.168.178.128 Windows=192.168.178.68 (using the linux subnet 192.168.178.xxx)
I sugggest to use the first solution in favour of the more standard 192.168.1.xxx private address.
When devices of different subnets have to talk each other you have to install a device called router, it has two network ports, one on a subnet and the other on the second network, which scope is to route packets between the two networks.

What is your physical connection between machines? Like the one below?

C++

                                    +-------- +
                               +----+ Windows | 192.168.1.68
+----------+    +--------+     |    +---------+
|  Gateway +----+ switch +-----+
+----------+    |        +-----+
 192.168.1.1    +--------+     |   +----------+
                               +---+  Linux   | 192.168.1.128
                                   +----------+

If you ping the Linux server from windows can you see it?
And the reverse?
From windows machine is all ok?
Are you sure that the Linux server IP address is effectively 192.168.1.128 ?
