Hiya Wondering if someone can point me in the right direction. I am trying to use samba as a PDC, and have 40 windows XP machines log into it. The problem lies in that sometimes it logs on, and sometimes it fails with "Windows Cannot Connect to the Domain". I have set the "always use secured certificates" to disabled already but no luck. Any suggestions would be helpful. smb.conf file below.
