hi dada,
well there are lots of resources on the web to help you get started. a quick google search returned me these results which may provide additional info on your situation:
first off the official
samba howto
then you may try this
link
from LinuxHomeNetworking
you could also take a look at
this
also from LinuxHomeNetworking with regards to adding workstations to your domain.
you may try and configure your linux domain on a test environment first and then adding a test windows host to check your configuration.
hope this helps.
