Just to be sure what's the content of your resolvconf ?

Hello,

I played around with DNS to isolate the issue, why I have problems with a 
second DC whose name can't be resolved after joining: It seems that if I add 
entries to the DNS (with the windows DNS tool or samba-tool), I can't resolve 
them (but they are there visible e.g. in the windows DNS tool).

# samba-tool dns add 192.168.29.2 muc.medizinische-genetik.de marc A 
192.168.29.76 -Uadministrator
Password for [MUC\administrator]:
Record added successfully

[root at Test_DC1 local]# host -t A marc.muc.medizinische-genetik.de
Host marc.muc.medizinische-genetik.de.localdomain not found: 2(SERVFAIL)



Other DNS entries resolve fine:
# host -t A exon.muc.medizinische-genetik.de
exon.muc.medizinische-genetik.de has address 192.168.29.2

# host -t SRV _ldap._tcp.muc.medizinische-genetik.de.
_ldap._tcp.muc.medizinische-genetik.de has SRV record 0 100 389 
exon.muc.medizinische-genetik.de.



We are running rc4 + bind 9.8.4.


Regards,
Marc
