Windows 10: cannot access shared folders on my server but i can use remote desktop

Hi i'm slowly going through various posts which are similar to my above problem but looking for a quick answer.
Essentially my problem is this, I have a home server, 3 PC's, 2 TV's and a bluray player which all used to be able to see each other i recently had to reinstall windows on one of the PC's due to a drive failure i cannot now access any shared folders on that PC, i also cannot see any shared folders on any of the other devices, i can however access the server via remote desktop from that PC. In libraries the Network icon shows connect devices. My other PC's are all running win 10 1803 plus one of them also has a fresh install but is not suffering the same problem.

Thanks for any help

:)

 

Remote access to my (local) server's folders

But what if he tries to access this mapped drive when he is not on the same subnet of his server ?

 

Shared folder access

Hi,

Remote access to my (local) server's folders

I am running a simple local fileserver. Windows based.

I would like to access (load, save, modify) what's on this server when I am away on business trips. Laptop -- internet -- router - server

What is the best way to do this? Setup WebDAV or ftp-server or something else? I would prefer direct access, ie. being able to load/save from an application rather than using ftp as a separate step.
