How can I join a windows domain and share files?

How can I join a windows domain and share files? -- Linux general technology-Linux technology and application information. For details, refer to the following section. This afternoon I want to perform an operation: linux redhat 9.0 to access the stuff in a network shared directory of windows xp. Two problems:
1. If the windows xp server is in the test.com.cn domain and my linux server is not added to the domain, can I access windows sharing? In the afternoon, I tried to add linux to the domain, but it was not successful. My operation was to execute setup on the linux terminal, select authentication, and then find winbind Based on the online method, but I couldn't find it, my samba component is installed, and the winbind service is also up and cannot be found. I don't know why? Could you tell me how to add linux to the domain control domain of windows server 2003?

2. How to Use samba to Access windows Shared Files? Can you describe the detailed method?

Thank you!
