My problem has the same error described in this thread but it is behaving defferent:
https://social.technet.microsoft.com/Forums/windows/en-US/ab9340b5-846f-4b75-921d-8442c8540bb6/problem-with-accessing-a-windows-share?forum=w7itprosecurity
I am using a laptop and a PC (both Windows 10). I think the problem is on the PC but I'm not entirely sure
I have shared a folder on the PC and when accessing it from the laptop it gives the following error:
"\\servername\sharename is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.
A device attached to the system is not functioning"
It gives that error only once. Every subsequent time I try to access the share it asks for me to enter network credentials.
My credentials don't work... Both devices are of course signed into the same Microsoft account with administrator privileges. The folders being shared are owned by and shared with that Microsoft account in the Advanced Sharing/Advanced Security menus with full access. File Sharing/Network Discovery are turned on for both computers on private networks ect..
The only way to see the error again is to unshare and reshare the shared folder on the PC, again it will show the error only once, and then send me into the credential loop.
The PC is able to access the share on the laptop no problem.
The PC has been accessible from the laptop before, I am not sure what happened
The thread above recommended trying the access the shares using ip (\xxx.xxx.x.xx\share) so i tried that and had the same problem but again it worked fine accessing shares on the laptop from the PC
Things I have tried:
• Reinstalling network adapter drivers on the PC
**sigh I will probably need to factory restore my PC to refresh my user profile. I will need to learn to make automated windows backups because little things like this seem to happen every several years after I have put a lot of work into the user profile :(
I don't think that you need to do that just yet. You have 2 pc's and a share named Music, correct? If you run these 4 commands on both pc's, do they work or fail? Or sometimes work?
net view \\thinktank
net view \\glassbox
dir \\thinktank\music
dir \\glassbox\music
All commands complete successfully on both computers at first.
But after removing the local account 'temp admin' from the ntfs and share permissions
dir \\glassbox\music
returns: 'Access is denied.' when run on \thinktank
furthermore after deleting the dword AllowInsecureGuestAuth, running
net view \\glassbox
on \thinktank does not show the music share
When you log on with your MS account, do you use the same password for pc's?
Is your MS account a member of the Administrators group on both PC's?
Run secpol.msc and compare the "Access this computer from the network" setting on the 2 pc's.
Yes I am logged in with the same MS account as administrator on both PCs I use the same password (I use a pin) for the ms account on both PCs
secpol.msc does not appear to be enabled on my system (\glassbox)
however when running secpol.msc on the laptop (\thinktank) it opens the policy editor successfully
"Access this computer from the network is displaying the appropriate data on \thinktank"
Search for "local security policy".
search returns nothing on my system
The file does exist in my system (searched with everything)
However attempting to opens any of these files results in error:
MMC cannot open the file (path\secpol.msc)
Try running C:\Windows\System32\secpol.msc.
(I use a pin)
Can you switch back to using a password and see if that works.
Try running C:\Windows\System32\secpol.msc.
I'm going to have to research that one.
Is it not available on both PC's? Are they the same Win10 version? Home? Run winver.
Can you try using a password instead of a pin?
