network ports to access domain shares from computers in workgroups

Hello!

We must open minimum ports to access domain shares (domain controllers and member servers on virtual hosting) from computers in isolated security workgroups. What ports should we open (NTLM, SMB, RPC, DNS)? Client, including Windows XP), will use the SMB URL: \\server\share_folder

Thanks
