Hello, I have big trouble with the domainlogon. My Win2003 server say, that the RPC-Server isn?t available. This problem comes sometimes and I can't see anything in the logs. That?s what I have: - SAMBA PDC with LDAP-Backend (3.0.24-6 DEBIAN) - SAMBA BDC with LDAP-Backend (3.0.24-6 DEBIAN) - both servers are in the same network - two Win2003-TS-Server that are in an other network - the problem is, I want to say, never on both win2003 servers together Here my configs PDC: [global] netbios name = XYZ-PDC workgroup = XYZ server string = PDC auf SERVER11 log file = /var/log/samba/log.XYZ.%m lock directory = /etc/samba/XYZ.lock max log size = 1000 panic action = /usr/share/samba/panic-action %d os level = 64 passdb expand explicit = Yes load printers = yes printing = cups printcap name = cups addprinter command = `/usr/sbin/lpadmin -p` domain master = yes domain logons = yes security = user encrypt passwords = true preferred master = yes local master = yes server signing = yes client schannel = no server schannel = no client signing = no smb ports = 445 139 137 ldap passwd sync = Yes unix password sync = no wins support = yes wins proxy = yes ldap admin dn = "cn=admin,dc=xyz,dc=de" ldap delete dn = no passdb backend = ldapsam:"ldap://xxx.xxx.xxx.xxx:389" ldap suffix = dc=xyz,dc=de ldap group suffix = ou=Groups,sambaDomainName=XYZ,ou=samba ldap machine suffix = ou=Computers,sambaDomainName=XYZ,ou=samba ldap user suffix = ou=Personen BDC: [global] netbios name = XYZ-BDC workgroup = XYZ server string = %h server (Samba %v) log file = /var/log/samba/log.XYZ.%m lock directory = /etc/samba/XYZ.lock max log size = 1000 panic action = /usr/share/samba/panic-action %d os level = 64 passdb expand explicit = yes domain master = no domain logons = yes security = user encrypt passwords = true preferred master = yes local master = yes ldap passwd sync = Yes unix password sync = no wins support = yes wins proxy = yes ldap admin dn = "cn=admin,dc=xyz,dc=de " ldap delete dn = no passdb backend = ldapsam:"ldap://xxx.xxx.xxx.xxx:389" ldap suffix = dc=xyz,dc=de ldap group suffix = ou=Groups,sambaDomainName=XYZ,ou=samba ldap machine suffix = ou=Computers,sambaDomainName=XYZ,ou=samba ldap user suffix = ou=Personen Have anybody the same problems or can help me to locate the problems.
