I was informed not to use HomeGroups, instead use regular Networking !
I've given all computers the same workgroup name as was suggested instead of using Homegroups, specifically a Windows7 computer can see the shared folders on a Windows8.1 computer, but the Window8.1 computer can't see the folders on the Windows7 computer ? Aswell the Windows8.1 computer (client) can't access the NAS, but the Windows7 computer (host) can. If I try to map a NAS as a network drive on the Windows8.1 computer, I get this error; the NAS has it's own unique IP and is connected, not to a router, instead a modem/gateway.
Not following a suggestion I was given, not to use HomeGroups as they are not reliable, when I try to join or leave a HomeGroup on the Windows8.1 computer these errors switch repeately, as in every second in Control Panel > HomeGroup
Before HomeGroups, I use to with Windows2000 and earlier versions of Windows setup shared folders and drives, that information I have forgotten, if anyone wants to help ? Aswell getting the, specifically client computers to see the NAS has had four suggestions and remote help from various people who thought they could get it to work, all failed, instead threw their hands in the air and said the situation is a odd problem ?
