LinuxQuestions.org - samba and win2k AD / HELP!!

Okay
I've been struggling with this for a while now.. I will post my smb.conf and krb5.conf and kdc.conf in a few minutes, just need to get into linux first.
Okay my question is : currently we are running a win2k active directory here, my PC's DNS is ops009.engineparts.co.za is engineparts.co.za my domain ?
when I choose My network places --> entire network --> Microsoft network --> epbd01
all of the computers on our network is on there is epbd01 my domain name then?
I'm sure I am jsut confused by the terminology here, I need to get this Linux pc on the network so I am able to access some shares on our domain controller epb01 but I need to know what services needs to be running I basicaly only know of smb that should be running what are the others? (Okay obviously also kerberos as it uses it for authenticicating)

Will post conf files now..

smb.conf

netbios name = ops009
realm = ENGINEPARTS.CO.ZA
security = ADS
encrypt passwords = yes
#wins server = 192.6.1.51
#ads server = 192.6.1.51
workgroup = epbd01
hosts allow = 192.6.
password server = 192.6.1.51
#winbind separator =+
idmap uid = 10000-20000
idmap gid = 10000-20000
winbind enum users = yes
winbind enum groups = yes
template homedir = /home/%D/%U
template shell = /bin/bash
winbind use default domain = yes

krb5.conf

[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log

[libdefaults]
ticket_lifetime = 24000
default_realm = ENGINEPARTS.CO.ZA
#default_tgs_enctypes = des-cbc-crc des-cbc-md5
#default_tkt_enctypes = des-cbc-crc des-cbc-md5
#forwardable = true
#proxiable = true
dns_lookup_realm = false
dns_lookup_kdc = false

[realms]
ENGINEPARTS.CO.ZA = {
kdc = 192.6.1.51:88
admin_server = 192.6.1.51:749
default_domain = EPBD01
}
[domain_realm]
.engineparts.co.za = ENGINEPARTS.CO.ZA
engineparts.co.za = ENGINEPARTS.CO.ZA

[kdc]

[appdefaults]
pam = {

krb4_convert = false
}

and kdc.conf
[kdcdefaults]
acl_file = /var/kerberos/krb5kdc/kadm5.acl
dict_file = /usr/share/dict/words
admin_keytab = /var/kerberos/krb5kdc/kadm5.keytab
v4_mode = nopreauth

[realms]
ENGINEPARTS.CO.ZA = {
master_key_type = des-cbc-crc
supported_enctypes = arcfour-hmac:normal arcfour-hmac:norealm arcfour-hmac:onlyrealm des3-hmac-sha1:normal des-hmac-sha1:normal des-cbc-md5:normal des-cbc-crc:normal des-cbc-crc:v4 des-cbc-crc:afs3
}

as far as I know these are the only files I have altered, please tell me if I need to configure more of them. Am I on the right track with my current configuration, my main problem is that net ads join administrator@ENGINEPARTS.CO.ZA gives me a nt_status_bad_network_name so I can't join the network, I know for a fact that I have some mistakes in the config files... can someone pleaaaaaaaaase help me out! :(
