First, if you happen to use the email login system I won't write there is a fix. I go back to local logins. (always.)
Next if a network share is getting permission issues, I always see if I have an account on the PC that is serving up the content. Yes, that's well discussed and not a Homegroup issue.
I can't tell what sharing system you want to use, login details and more. For some, they don't want the security so they enable the Guest account.
--> Be careful here. Some folk take multiple tries to understand that when a share is to All Users that means users with an account. The Guest account opens it from all users to any user. The difference eluded many.
I am having issues with sharing folders over my network after a recent upgrade to Windows 10. Here are the details:
I have 2 computers on my home network. One, an HTPC, running Windows 8.1 and a second, Desktop, which I recently upgraded from Windows 7 to Windows 10.
The HTPC is used almost exclusively to run Kodi/XBMC. It also has the majority of my media stored on its HDDs, except for one drive of media which is in the Desktop.
Prior to upgrading, the HTPC had access to said drive over the network through Kodi/XBMC via SMB. After I upgraded the Desktop to Windows 10, the HTPC no longer had access to these files. Kodi/XBMC can see the computer on the network, but cannot access it/any shared folders.
Here is what I have tried to far:
-Disabled password protected sharing on both machines
-Disabled firewall on both machines
-Disabled anti-virus/Windows Defender on both machines
-Shared both the root drive as well as specific folders on the drive, giving full read/write access to 'Everyone' in the homegroup
-Attempted to directly map the network drive to the HTPC. When I try to do this via the Desktop's name, I get error code 0x80070035. When I do it with the Desktop's IP, I can map the network drive, but when I try to access it, I am told I do not have the proper permissions.
I'm not sure what else, if anything, I am missing to make this work. Any tips would be greatly appreciated. Let me know if there is more info I need to supply to help troubleshoot this issue. Thanks.
