samba as pdc and share

Question

I recently had my ubuntu 8.04 server die so im rebuilding it with 10.04 lts

I had the system setup to be the domain for a few laptops and to share folders both shared dirs and the persons home dir

I've been useing the samba gui that comes in 10.04lts and I'm able to see shares become avaliable as I create them

I however do not seem to be able to add any laptops (xp) to the domain its giving me an error that it does not see the domain contorler.

I would prefer to work with it via the gui as im not 100% comfy with the command line but I can if there is no other option.

here is my current smb.conf file
