how to add a machine to a domain

friends,
last night I had been trying to create a domain controller and add a machine to the domain


I have two machines
the first is running the operating system windows 2003 server
the second has the operating system windows xp home editition

I have installed ADS in the first one and then tried to add the other machine to the domain but the problem I had encountered that when I right-click my computer/computer name/change

I don't find the option member in a domain which means that I can't add it to a domain att all

can any one tell me what is the reason behind that? noting that all IP addresses and dns are correctly given to each machine

XP Home can't be a member of a domain, but it can connect to domain resources. You do that the same way you map a network drive. You have to use a domain username / password for a user that has access to the domain resource (e.g. folder) you are trying to connect to. But, it can be done.

However, XP Home cannot participate in the centralized domain itself (for example, user accounts, account access and security, etc.).
