Mapped network drive not accessible from all PCs

Hello,
The problem is, our router is not detecting the drive. I contacted our ISP, who advised this is the way the routers are configured - they cannot enable usb sharing for security reasons Sad

So, as an alternative, I thought I would connect the drive to my computer, and leave it powered on so I can share the drive across the network - which I have done to some success.

Now here is where the problem lies - my computer (and 3 others) are connected to "Network 1" - I can share the drive with these computers with no problems. However other computers are connected to "Network 2" and won't detect the drive as I am on a different network.

As I mentioned, we are connected to a single switch and a single router (as far as I can see)

So, how would I go about making the drive available over the entire network?

Once again, I'm not a pro so any help would be most appreciated
Thank You


I didn't find the right solution from the Internet.
