Access to a sub domain with a computer in another domain

[scots_gal]

We have several sub domains in our network. If a user is from a different domain, does his computer need to be added to the subdomain for him to get accesss (with his newly created subdomain account) - or does the fact that he is from the main domain automatically give him access to the sub domain, enabling him to login with his subdomain user account ?

In a domain environment based on access to objects can make a list of items ACCESS. Users get this show when they login to the domain controller, and displays a user can access what resources on the network. When a resource that is not the domain, as its location, ACCESS LIST token cannot define the resources to users, as this remedy is not on the boards of the DC resources. I suppose you think username and password local computers in your workgroup and user names and passwords on your domain.
