[Samba] new user setup

[J Marsh]

I am very new to Linux and Samba. I have set up a Linux server and
connected it to my Win2003 network as an Intranet. I now want to set
up Samba to administer the Linux server from a WinXP station. I have
read the start of the documentation and it talks about the Samba
server having a name - mine doesn't - how do I give it one?
Also I need a domain name - is this the domain name of the Win2003
network, ie harrogategs ?
TIA
