Hi all, I think that my question has been asked several times but I don't find for the moment any way to resolve my problem. I have a samba server on a redhat EL 3 which is the PDC of my domain, it's my wins server too. In this one, I have 4 Windows 2003 servers, and one of them is my DNS. The others servers are used for Citrix connections. I have several workstations too. All of my machine are in the same domain. I don't use Active Directory nor LDAP. I don't want to use AD because in this case I won't use samba. I can open a session from any workstation, and I can get my scripts profiles from the Samba. My problem is that I can't connect from any Windows 2003 servers, and that with any login I created on the samba. I tried to change some security in the 2003 servers. I created my servers as my workstations in the PDC. Thanks in advance for any help. Franck
