I have a charity network with 13 desktops and 3 laptops, all running Windows 7, that connect to a Ubuntu server running Zentyal as a domain controller and file server.
The desktops all connect fine (all hardwired), but the laptops, connect through Wireless, can't log on to the domain.
I'm sure it's a security setting somewhere, but I'm at a loss as to what is causing it ... firewall, Ubuntu or Zentyal.
Router/Firewall is :
Software FIrewall is through Zentyal
If that helps at all.
Thanks in advance for any help.
