“I can ping my Samba server from Windows, but I cannot ping my Windows machine from the Samba server.”

The Windows machine was at IP address 192.168.1.2 with netmask 255.255.255.0, the Samba server (Linux) was at IP address 192.168.1.130 with netmask 255.255.255.128. The machines were on a local network with no external connections.

Due to inconsistent netmasks, the Windows machine was on network 192.168.1.0/24, while the Samba server was on network 192.168.1.128/25 logically a different network.
