Windows 10: "Permissions" problems: can't share files on home LAN computers

Does this help ?
Manage Stored User Names and Passwords in Windows 10

 

Thank you. I had tried this but it didn't work. I ultimately resolved it easily enough after trying a few other ways, by simply granting permission to "everyone" on the network drive.
Thanks again.

 

One thing I don't know if many people realize is that when you're running a LAN without a domain controller you're not really sharing.

So for our example let's say we have a laptop and a desktop that we'd like to be able to move freely about without having to effectively eliminate the security.

You must maintain the same Userid on both machines and the same password and this is what confuses most people. When you access a shared drive on the desktop from the laptop either by mapping the drive to the laptop or just logging in as needed through various ways it's a flaw in Windows that allows you to work seemlessly assuming your machines are all on the same version of Windows.

Windows for whatever reason doesn't verify that you're the same person on the laptop and the desktop it assumes you have the same Userid and as long as the passwords are the same it assumes you have security rights to the desktop but you really don't because effectively in a Workgroup your security is prefixed with the machine name so when you granted access to whatever you wanted on your desktop to your Userid it officially looks like Desktop\Userid\Drive\Directory\File or whatever level you're granting yourself access to. So now you can guess that on your laptop it's exactly the same except that high level qualifier is no longer desktop but Laptop.

You really shouldn't have access to anything on the desktop because effectively you are two different Users and this is where the trouble begins. I'm guessing that to access the other machines on the LAN Microsoft was like we can't give domain controllers to people that just want to connect their home computers together they'd spend their life maintaining it and we lose the desktop OS war. So what I'm guessing is that they substituted Workgroup into that high level if they're unable to find a domain server. You kind of find this out when you try to connect the odd Linux machine onto your home network and it doesn't have a default Workgroup and you go around cursing for several days trying to figure out why the two won't work together. If you don't have your laptop and desktop both with the same name in the Workgroup that will cause you access problems.

Another problem that occurs when you create your home LAN is when software tries to access LAN drives. For example I use my desktop as a pseudo-server and so one drive has all my music files on it and that's shared out to my phone by using a cloud server and my laptop it's done through a shared mapped drive but today was the first time in a long time I've tried to go into iTunes and got snagged because of some security issue which is how I got here although this doesn't address my problem I thought I would share what I've learned since converting to Win10. Lord help you if you have machines on different versions of Windows because then the security really becomes a problem and you won't be able to access drives just by sharing them.

I know you've resolved your problem to your satisfaction but maybe this explains why you've had to resort to setting the security to everyone with all access granted.

 

I almost forgot. On your desktop you've probably established yourself as an admin and you've probably done the same on your laptop but they are not the same administrator. So what you find out when you try to access something on the desktop is that even though you think access is granted to the administrator for some reason they (Microsoft) doesn't use that Workgroup replacement when you belong to a group of users and so you can't access things on your desktop as an administrator of the laptop or vice-versa if your trying to get from the desktop to the laptop you occasionally find yourself blocked.

Sometimes the easiest way is to just use a remote desktop if it's not something you'll be doing over and over (not included on the home edition but you can use VNC which seems to work for me although you may have to change some setting related to remote desktop in the firewall I believe) otherwise it might be best to grant your userid access to that disk resource from the machine it resides on.

 

Having a heck of a time with sharing on my home network between my daily/internet pc and my game rig.
Everything was fine but I reloaded my daily. Go in to the network settings to setup the local network shares and manually shared (everyone) the folders I wanted with proper permissions.
My daily can see my game rig along with our networked printer when I click Network from the file manager/explorer/what ever it's called in win 10 and they are listed under Computer.

My game rig though can't see the daily computer or the printer under Network/Computer. They both show all the media devices, multi, network infrastructure, other devices, printers, scanners below where the computer section is or should be on my game rig.

Each computer is listed for in-home streaming through Steam on the other but they don't show up in Network to be able to share files. My game rig can see itself in network but the daily computer cannot see itself or my game rig under the computer listing. I assume the issue is with my daily.

 

Are they both running the same OS?

 

Seeing as there wasn't a quote to your message I don't know if your asking me or someone previous in the thread. Both my computers though are on the same exact build of win10 pro x64.

I should also add that when each one boots after the other has been running I get the pop up from Steam that the other computer is available for streaming. Which is nuts considering I can't view files that are on my daily (The computer doesn't even show up let alone the shared folders although printer and itself show up under network/computer via This PC) from my game rig but I can view the one shared folder I have on my game rig on my daily. So network file wise only one computer can see the other not the opposite though. But either computer can stream Steam apparently to the other as per the Steam pop up message saying the opposite computer is available for streaming.
