I am Using MDK10.1 with samba 3 (and a bit) configured as primary domain controller in a small network with XP pro on the other PC. I have actually managed to get the other pc to join the domain and Samba appears in the network places folder on XPpro.
So far so good(it hasn't been easy) and after realising the firewall was blocking local connections to linux, it now seems to be up.
However when I try to logon to the domain as a user, or anything else, in XP the pasword chat just cycles. I can only login to the xp box as the client.
When I try to access the samba server in network places I am getting the same behaviour the passchat just cycles.
Can anyone of you Gurus help me to troubleshoot this problem, I have been at this for several weeks now, and checked out the Samba manual loads.
My smb.conf file contains the following:
