Samba Shares stopped working after recent Windows 10 update

@mitu I don't understand the entire output but it looks like Samba is running fine.

[mitu]

Yes, it works fine (as expected), the issue is on the Windows side.

EDIT: can you try installing wsdd and see if it changes anything on the Windows side ? It's a simple script which you can run from the command line to test if retropie is visible again on the network from Windows.

@philbobaggins Please open the command prompt in Windows 10 and run:

net use r: \\retropie\roms

@mitu Could this have to do with the disabling of SMBV1? Would forcing SMB3 on the Pi help with Win 10 communication?

Interesting. I thought enabling "Enable insecure guest logons" for my Lanman Workstation config would have allowed guest access. Apparently not (see below). I don't suppose you have a solution?

No, it's not a matter of protocol. Both Linux (on the Pi) and Windows don't use SMB1 by default and Windows even disables it by default on new installations since Win 10.

This registry value should work:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters] "AllowInsecureGuestAuth"=dword:1

@jengun That did the trick! Thanks a lot for your help and insight. Hopefully this is a solution for others. FYI @gmsinger8808

Glad it works because, to be honest, I don't have Windows 10: it remains a mystery to me that helpful error messages only appear on the command line and that updates sometimes overwrite settings. Why SSH doesn't work for you remains to be clarified (in another thread) ... :-)

@PhilboBaggins - thanks for this, annoying Microsoft just disable features and then do not show any alert when attempting to use them. I also see you can edit this via Local Group Policy Editor (https://www.nodeum.io/howto/guest-access-in-smb2-disabled-by-default-in-windows-10)

@TrisM Though it is an old thread and I haven't asked/wondered aloud back over nearly 2 years ago, was considering it to be just a SEP. But as you revoked revived the thread I am doing it now, because now I am really puzzled/curious and doubting again: I have Windows 10 Pro on 2 desktop + 1 laptop machines since the EOL of Window 7 and a third desktop setup in 2020. None of them had this behaviour and on all four (3 on 22H2, my laptop still on 21H2) this Group Policy is still defaulting to "Not configured" [edit: besides Mitus remark in the early posts that it is disabled as default on some mints of win10 and that's not including home/pro] . And as Win10 is using "Language Packs" (as it was on xp x64) instead of regional versions of the os itself, I somehow doubt that updates are meddling with those settings differently for different regions and I am still unsure why this was changed on some user systems and whether it truly was done by the M$ Update or by other means and if yes under what circumstances this would have happened.
