[Samba] Unable to join to Windows 2003 PDC using samba 3.5.8 from a linux machine!!

[Rick Gates]

Hi all,

I am using samba 3.5.8 on a linux machine.
I am not able to join the domain of a windows 2003 server in ADS mode.

I am getting the following error message:

# /usr/local/samba/bin/net ads join -U Administrator%password -I 10.25.66.71

Failed to join domain: failed to find DC for domain ABCDOM.PQR.COM
#

I am not sure what the issue here.
It works absolutely fine when I try to join the domain in rpc mode.

# /usr/local/samba/bin/net rpc join -U Administrator%password
Joined domain ABCDOM.
#

The smb.conf used is:

# /usr/local/samba/bin/testparm

NOTE: 10.25.66.71 is the IP of my 2003 windows server.

My lmhosts file is:

# cat lmhosts.

10.25.66.71 ABCDOM#1c

It would be great, if any one can tell me if there is anything wrong here
and probably help me sort out this issue.
Thanks in advance!!

Thanks,
Rick
