[Samba] smbclient works with IP address but not hostname

[Graeme Russ]

Hi All,

I've configured a Fedora 20 server with samba to share a few user 
directories and a printer.

 From a Windows 8 laptop, I am able to address the samba server by it's 
name (fs1)

 From a Fedora 20 client (ws1), I am able to address the samba server by 
IP address, but not by name.

[gruss at ws1 ~]$ smbclient --version
Version 4.1.15

[gruss at ws1 ~]$ smbclient -L 192.168.1.10

[gruss at ws1 ~]$ smbclient -L fs1

protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE

The server is able to fully resolve ws1. I had to first start the nmb 
service on ws1 with:

[root at ws1 gruss]# systemctl start nmb.service
[root at ws1 gruss]# systemctl enable nmb.service

[root at fs1 samba]# nmblookup --version
Version 4.1.15

[root at fs1 samba]# nmblookup ws1
192.168.1.209 ws1<00>

And the creepyconnors laptop:

[root at fs1 samba]# nmblookup creepyconnors
192.168.1.211 creepyconnors<00>

Here are the outputs from testparm:

Any ideas where I should start looking?
