I have two samba centos7 samba server VMs. One at work, one at home.
These are ansible servers and I have a share on them that I mount from
windows 10 workstations where I use sublime text to edit my playbooks.
They are domain joined (different domains) and use AD authentication - think
they are setup with Kerberos iirc , sssd realmd.
So this was all working find two weeks ago, then day before yesterday I
tried to access the shares and it says windows cannot access bla bla bla,
The logs look fairly normal but end

exit (NT_STATUS_CONNECTION_RESET)
With the NT_STATUS_CONNECTION_RESET
I've googled on this and nothing comes up that matches what is happening to
me. I have tried windows 7 and 3 windows 10 workstation and its all the
same.
They are still joined to the domain and I can login with ssh using domain
creds. Nothing changed on smb conf setup.
I know this is pretty vauge - I've followed some trouble shooting steps.
Smbclient -L lists it fine, firewall is turned off, selinux is disabled.
The fact they both quit working at about the same time seems to point to
windows updates, I don't think I ran yum update on them - doubtful that I
would have run on both especially. maybe a windows update? But seems like
a lot more people would be asking this. Appreciate any ideas on this I can
try.
Interesting, I just tried to login with the smbclient and the ad user I ssh
in with and that tells me NT_STATUS_NO_LOGON_SERVERS
Yet I can still authenticate my AD GUID for SSH so that message must be
wrong.
