[Samba] Shares not accessible when using FQDN

Tue Aug 29 09:26:41 UTC 2017

Hai, 

Without (smb.conf) config, no, sorry, no ideas.. 
And educated guess, you have errors in you DNS resolving. 

Whats the OS running? 
Cat /etc/hosts
Cat /etc/resolv.conf
Cat /etc/smb.conf 

On the windows pc. open dosbos,
ipconfig /all 

Things like that, suprisly, really help us out in helping you. ;-) 

Greetz, 

Louis
