"The account is not authorized to log in from this station." if trying to map drives to samba server

Hi Martin,

As you are facing this issue using a Samba server, your query would be best suited in the TechNet forum. Kindly, post your query in the TechNet forum.

Thank you.

Thanks for the offer, but I see from another thread in here (and on other forums) that this seems to be a new 'feature' in the latest build, that is affecting a lot of other people with network connections to other Windows machines, NAS drives etc - not just Samba.

Ok, thanks to a reply on Technet I have a workaround for this that seems to work !

Using REGEDIT it's necessary to create a DWORD value called 'AllowInsecureGuestAuth' in HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters and set this new value to 1. A reboot will also be necessary.

I worked on this exact issue for HOURS last night.

I found that it really didn't like connecting to my samba share as an anonymous user/guest.  All other devices in house worked fine.  

How/where did you find this solution!?  Hopefully this is bugged and fixed by the final release.  I've got quite a few open fileshares deployed that will have issues with this if it stays the same way.

Have the same issue on a WD NAS running samab 4.0.9.

even if in smb.conf , public is set to yes, since january build, an ntlm authentication is tried

if "max protocol" is set to "SMB2" or "SMB3". When using "SMB1", everything seems fine.

It makes somewhat sense that for accessing Information, authentication should be required.

For the moment, I will leave my samba running with smb1, but am interested to hear, if the issue can be solved by requesting authentication on samba side.

Hi Martin,

Thank you for sharing the solution on this forum. This would help others facing similar issue. Feel free to post if you have more queries with Windows in the future.

Microsoft has started a discussion about the security change in build 9926 that brings up this error.

I have the same config than you and it kinda worked for me. It still does not appear under Network but at least I was able to mount it as a network share and access the data. Hopefully they'll be a fix soon otherwise I foresee lots of troubles for home users and SME's!
