[Samba] Suddenly Windows clients can't join Samba+ldap PDC anymore
Hi, thanks a lot for the tips. I already did the first one, importing the following into the registry: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManWorkstation\Parameters] "DomainCompatibilityMode"=dword:00000001 "DNSNameResolutionRequired"=dword:00000000 I didn't do the second tip but it looks like it's not needed for Windows 7 OS and i also had the same issue on a Windows 7 VMWare machine. I'm going to try it and see what happens. Thank u!

[Samba] Suddenly Windows clients can't join Samba+ldap PDC anymore
Hi, i've tried adding server max protocol = NT1 into /etc/samba/smb.conf and restarting smbd and nmbd services but it didn't do the trick. I feel like Windows clients are not able to resolve SRV1 into the PDC and so they can't event try to join the domain.

[Samba] Suddenly Windows clients can't join Samba+ldap PDC anymore
I was trying to fix a problem on Windows 10 with Outlook 2013. Also
running an NT4-style domain. The machine had already been joined to
the domain and outlook had been working but recently not (probably after
patch tuesday.) I also had had problems with Win 10 mail and RDP.
I came across the following link.
*http://superuser.com/questions/1019862/how-to-connect-windows-10-joined-to-samba-to-a-microsoft-account*
"Open the registry editor (regedit.exe), navigate to
|HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb|
and add a new DWORD subkey |ProtectionPolicy| with the value |1|."
Seemed to fix my e-mail and RDP issues. I don't know if I would have
been unable to join the domain , since the machine was already joined.
