I face an issue regarding file sharing between Windows computers over different sub-networks.
The network topology is as shown here:
There are two sub-networks which are connected together with PPPT by using two Mikrotik routers (please ignore the figure showing PPPoE).
The purpose is to make the Windows 2008 server (that is part of the 192.168.1.0 sub-network) accessible to all computers for file sharing.
So far, computers A and B are able to access the shared folders of the server.
Unfortunately, the shared folders of the server are not visible to computers C and D.
I would like to mention that computers A and B can ping computers C and D and vice versa even if they belong in different sub-networks. Also, all computers can ping the Server.
So, even if all computers are visible to each other why can't computers C and D "see" the shared folders of the server?
All computers use Windows 10.
Please let me know if you need more information.
