I have previously been using an older version of samba 1.9.16p9 , and would like to establish a trust relationship between an actual NT 4.0 server and my UNIX server running samba. Do I need the newer versions of samba supporting domain options stuff like; domain master and preferred master ?? Everytime I try to establish the trust, on the NT box, I get "could not find domain controller for this domain". Which made me think that maybe the samba box needs to be configured as a PDC or BDC??? Regardless, both machines are on the same physical network and within the same subnet, and I can ping between them. Any ideas? I'm trying do this so that my nt server can access a dummy account on the samba side for a unc share. Thank You, Kevin Oleniczak
