[Samba] name resolves to public address - should resolve to private...

[Joe Demeny]

On my network I have one Samba PDC (Version 3.0.28 running on FreeBSD
6.3-PRERELEASE), one mail server (FreeBSD + Dovecot + Postfix) and a
dozen or so WinXP/Win2K machines. The WinXP/Win2K machines all have
static IP addresses.

The Windows clients are configured to look up the Samba PDC machine for
both DNS and WINS. The Windows clients seem to be able to find other
machines as well as the PDC:

Z:\>ping pilot-ws

Pinging pilot-ws [10.10.10.34] with 32 bytes of data:

Reply from 10.10.10.34: bytes=32 time<1ms TTL=128
Reply from 10.10.10.34: bytes=32 time<1ms TTL=128
Reply from 10.10.10.34: bytes=32 time<1ms TTL=128
Reply from 10.10.10.34: bytes=32 time<1ms TTL=128

The Windows clients can also find the mail server:

Z:\>ping mail

Pinging mail [10.10.10.253] with 32 bytes of data:

Reply from 10.10.10.253: bytes=32 time<1ms TTL=64
Reply from 10.10.10.253: bytes=32 time<1ms TTL=64
Reply from 10.10.10.253: bytes=32 time<1ms TTL=64
Reply from 10.10.10.253: bytes=32 time<1ms TTL=64

But, the Windows clients resolve the FQDN of the mail server to the
public IP address:

Z:\>ping mail.mycustomer.com

Pinging mail.mycustomer.com [aaa.bbb.ccc.ddd] with 32 bytes of data:

Reply from aaa.bbb.ccc.ddd: bytes=32 time<1ms TTL=64
Reply from aaa.bbb.ccc.ddd: bytes=32 time<1ms TTL=64
Reply from aaa.bbb.ccc.ddd: bytes=32 time<1ms TTL=64
Reply from aaa.bbb.ccc.ddd: bytes=32 time<1ms TTL=64

What I want is that the Windows machines resolve both mail and
mail.mycustomer.com to 10.10.10.253.

On the Samba PDC machine in /etc/hosts I have:

10.10.10.253    mail.mycustomer.com  mail

and the Samba PDC machine resolves mail.mycustomer.com to 10.10.10.253.

In smb.conf I have:

    wins support = Yes
    dns proxy = No
    name resolve order = wins host lmhosts broadcast

I would very much appreciate your insight...
