I am having difficulties to connect to a samba share from Windows10. The samba-share is located on a Ubuntu server 16.04.
I did some reading on the internet and did configure the share but can't connect from windows10.

Hopefully someone can help me I'm a bit desperate right now...

Accessing the server from windows file explorer gives the following feedback:

cannot access

diagnostics misspelled

diagnostics server exists

On forehand I did the following within the Ubuntu server:

Configuring /etc/samba/smb.conf:

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.

I did use the following commands to add a group on the data16 directory.
User rick has access to the directory and I checked he can access that directory from within the Ubuntu server. I created some test-directories there.
I used the following commandline commands:

rick@RVSERVER16:/mnt/raid5$ sudo groupadd data16
rick@RVSERVER16:/mnt/raid5$ sudo usermod -a -G data16 rick
rick@RVSERVER16:/mnt/raid5$ sudo mkdir data16
rick@RVSERVER16:/mnt/raid5$ sudo chgrp -R data16 /mnt/raid5/data16
rick@RVSERVER16:/mnt/raid5$ sudo chmod -R 777 /mnt/raid5/data16
rick@RVSERVER16:/mnt/raid5$ sudo chmod g+s /mnt/raid5/data16
rick@RVSERVER16:/mnt/raid5$ sudo smbpasswd -a rick
Added user rick.
rick@RVSERVER16:/mnt/raid5$ sudo restart smbd
rick@RVSERVER16:/mnt/raid5$ sudo restart nmdb
rick@RVSERVER16:/mnt/raid5$ sudo /etc/init.d/samba restart

Finally a view on the directory info:

Thanks to Thomas the problem is solved, thanks man:
You share definition is broken. You have commented out ;[profiles] which should serve the /mnt/raid5/data16 path. So remove the comment ; and try to connect via rvserver16profiles. – Thomas 1 hour ago

I did remove the " ;" and restarted the samba service. Then I tried RVSERVERmntraid5data16 again. I got a login window but I was rejected with the smb password. Then I saw you said try to connect via rvserver16profiles. And then, voila, I was connected and saw the test-directories. I am very happy.
