Sure, why not? You will retain your local accounts when you join the
workstation to the domain and will have a choice at logon of the domain
or "This Computer" - the local accounts.
A user in any version of XP can potentially access domain resources as long
as there is a domain account that exists that the user knows the
logon/password for and that can even match their local logon/password.
However only XP Pro computers can "join" a domain and then be able to be
managed centrally and have Group Policy applied to the user and
mputer. --- Steve
