[Samba] Problem with RPC and Win2003 Server

[Manuel Erber]

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.


Thanks
