[Samba] Trouble while join domain from Windows 2k/SP3 looking for SRV records
Hello, i have trouble when I'm trying to join a 2ktest SP 3 box into a samba 3 domain. [2. samba 3 configuration --- application/octet-stream; smb.conf]... The 2ktest (it's the name of the box) have 192.168.100.206 as IP Address, the samba 3 have 192.168.100.18. Here the tcpdump output when i try to join the domain : FMSTST is the workgroup name defined in smb.conf 16:53:17.829963 192.168.100.206.1054 > 192.168.100.18.domain: 18+ SRV? _ldap._tcp.dc._msdcs.FMSTST. (45) [...] Windows complains about it can't find the name FMSTST so, i set up a bind with some entries (especially one SRV record) domain.tld. 600 IN A 192.168.1.5 domain.tld. 600 IN A 192.168.1.1 domain.tld. 3600 IN NS srv-18.domain.tld. domain.tld. 3600 IN MX 9 srv-19.domain.tld. srv-18 IN A 192.168.100.18 pdc-fmstst IN A 192.168.100.18 2ktest IN A 192.168.100.206 _ldap._tcp.dc._msdcs IN SRV 10 10 389 srv-18.domain.tld. [...] now, i try to join the domain domain.tld, then i have the following tcpdump output : 16:58:50.413893 192.168.100.206.1057 > 192.168.100.18.domain: 20+ SRV? _ldap._tcp.dc._msdcs.fimasys.fr. (49) 16:58:50.414409 192.168.100.18.domain > 192.168.100.206.1057: 20* 1/2/1 (151) (DF) 16:58:50.420354 192.168.100.206.1058 > 192.168.100.18.ldap: udp 122 16:58:50.420413 192.168.100.18 > 192.168.100.206: icmp: 192.168.100.18 udp port ldap unreachable [tos 0xc0] [..] Why Windows try to access to LDAP server via *UDP* port ? I also try with a Windows XP, i have the same error, it try to find some SRV records. I don't understand where i'm wrong. I already success to have samba3/ldap as PDC but with more older Windows as members. Note I _can_ browser the PDC via its name (PDC-FMSTST) using IE (via \\pdc-fmstst). I join my samba 3 configuration, but I think the problem don't comes from samba. Thanks for your help -- Bruno Bonfils Fimasys
