[Samba] Add samba to a Win2003 AD

[Lars]

Hi

I trying to add a samba fileserver (v3@ Debian Sarge) to Windows 2003
domain. I've followed a couple of HowTo's including the officiel one, but
i'm having trouble even with the basic connection.
        "kinit administrator at dom.net"
"kinit(v5): Cannot resolv network address for KDC in requested realm while
getting initial credentials."

The Win2003-server is written in my "/etc/hosts", and i can't ping it.
General i'm having trouble understanding the different part, such as
"kerberos password server" and similar.

----- smb.conf ----- (192.168.0.2 = Win2003 server)
[global]
workgroup = debianserver
realm = dom.net
wins server = 192.168.0.2
security = ADS
encrypt passwords = yes
password server = dom.net

domain master = no
idmap uid = 10000-20000
idmap gid = 10000-20000


----- krb5.conf -----------
[libdefaults]
default_realm = DOM.NET

[realms]
DOM.NET = {
        kdc = WINDOWSSERVER.DOM.NET
        }

[domain_realms]
        .kerberos.server = DOM.NET


Any help is welcome, because googling around has brought me no futher..
