Joining the Linux server to a Windows AD domain

Hi ,

I have a domain contoso.com, which is created by Windows AD, i have a linux server which i want to join to this domain.
Linux server-: RHEL 5.3
Info of the windows domain*******
AD server- Windows 2008 r2 server.

Please help me to join this linux server to the windows domain.

I think you will need to be more explicit in order to get some help...
What are you trying to achieve? "Joining a windows domain from unix" is not much of a help... Is it for using ldap ( auth?)?, samba? ...

I want to add the linux server to the AD domain to transfer some files from the Windows server to the linux server. I think it will use the Samba!!
