Samba, trouble adding xp machines to my domain.
 

Hi.
I'm working on a project installing an openSUSE server as PDC in a Windows Network and I'm wondering, what do I need to do in order to get it working?
Prerequisites are: PDC, File and Print server with limited printing (Max 50 pages per user), Quotas (1GB), and security is of an essence. Later on, a webserver.

I'm new to Linux (only 1 month) and therefore I need to work with GUI. I come from a background as windows server 2003 administrator.
I have made several installs of openSUSE 10, 11 and 12. Now I'm using the latest version,12.2.
I have installed DHCP, DNS, Samba, SWAT, LDAP, Keberos and much more. I've done some configurations but I'm having trouble adding xp-machines to the domain (is it even a domain?). I can't get LDAP working together with DHCP or DNS, but it works with Samba (do I need LDAP?).

These are the services installed on my PDC1:

Which of these is unnecessary and which one do I need to focus on?

If you need further information I will post it for you.

Tnx
