So Samba4 has worked for the past 5 months with my current setup; however, today I attempted to connect to my share and I received this error:
\\{server} is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.
The specified domain either does not exist or could not be contacted.
Here is my smb.conf.
I have already tried restarting samba and restarting the server. I also found an error in the log.smbd. Which simply said that the port was already being used so smbd couldn't be started, I think that is b/c an instance of smbd is already running, which should be a problem.
