You're going to need quite a bit more information than what you're giving.

If you can get to the internet from that system, then you are on the LAN - sharing documents (usually) requires that you be part of the LAN's domain as well - which is an entirely different story.

To join your domain, you have to set up the system as someone who's authorized to do so (meaning they have that privilege on the DC - Domain Controller), then you'll have to log in to that system as a valid domain user, menaing a user who's account information is in (and controlled by) the domain controller.

If you're authorized to join the network, you should have such information available, or know who to talk to to get set up.

If you're interested in the technical aspects of this, I suggest you google for "Active Directory", and "SMB with LDAP and Kerberos"
