Today we install ubuntu 14.04.3 on pole2lp1. We found that the samba
server doesn't work well.

root@pole2lp1:/etc/samba# /etc/init.d/smbd status
 * smbd is running

root@pole2lp1:/etc/samba# smbclient -L pole2lp1
protocol negotiation failed: NT_STATUS_IO_TIMEOUT

We also tried to add a user and got the same result.
root@pole2lp1:/etc/samba# smbpasswd -a root
New SMB password:
Retype new SMB password:

root@pole2lp1:/etc/samba# smbclient -L pole2lp1
Enter root's password:
