CentOS - Nov 2019 - Centos 7 + samba / some win 10 systems can mount and some not

Hallo,

We are using centos 7 and samba in combination with Win10 1903.
The problem:
Some systems are able to map a share and some can t.
Any ideas and hints?

Thanks

Ralf

We have the same setup and have had no problems with clients mapping shares.

Some simple tips:

double check spelling of all usernames and that passwords on the clients
match that of the samba shares

try setting up a user that can connect on their pc with a login on one
that cannot, see if the problem follows the user or the pc

Check firewall rules on the windows clients to make sure there isn't a
block set up.

Best of luck.

Make sure server and all clients are on the same page wrt smb protocol versions.
Clients should have SMBv1 disabled. The server should enforce SMBv2 minimum.
What you describe sounds like the server uses v1 and some clients, i.e. the ones
that can't map shares, require v2.

Hallo,
thanks for the hints.
Firewalls are down and the share is configured for access without login.
Works fine with Win7 and some Win10 systems.
I m afraid that there is a mix of versions and patches active in the 
Win10 installations.
I need a solution that works without any changes on the Win10 sytstems.

Yes. Verify that selinux is not blocking the incoming connection from
windows. I've had that problem in the past and it's a pain.

For testing purposes only, on the linux system(s) that reject windows
SMB connection attempts, issue "setenforce 0" and see if it then
works.

If it does then work, reset that setting to "setenforce 1" (you
don't want
to leave selinux disabled) then look in /var/logs to see if you can find
a log of the failure. If you can find the selinux record for the failure
it should tell you how to apply a work-around for that specific issue,
so you do not need to totally disable selinux.

Good luck!
