I'm experiencing a networking problem which I asked elsewhere and so this is the problem and this was the solution I was given, unfortunately the solution doesn't work in Windows10.
The problem was non-existant six months ago, which is a latop and a desktop both running Windows10. As of the last few weeks I cannot connect to a shared folder which lives on the desktop from the laptop. When I attempt to connect to the shared folder from the laptop I'm prompt for the login and pass, and I've tried all the login and passwords which I have and nothing is connecting ?
And so this is the solution which hasn't worked.
Method 1: I suggest you to run the shared folder troubleshooter as below and check if it helps.
Press Windows key +X, select Control panel.
Change the view by option on the top right to Large icons.
Click on troubleshooting and click on the view all option on the left panel.
Method 2: I suggest you to follow the below steps to change the settings.
Go to your hard drive and right-click the folder that's causing all the trouble.
Click the Security tab
Then click Advanced
You'll see a window with some usernames. Now click Owner in the tabs above.
Click Edit, then select the username you wish to be able to open the folder and be sure to check the box that says "Replace owner on subcontainers and objects" then hit Apply.
A pop up will come up that says something like 'You have replaced the ownership for the selected folders' or something in that manner.
