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

You'll need DNS (udp/53) for resolving names, and CIFS (445/tcp) for the shares. The old SMB and NetBIOS ports (135, 137-139) can help speed up access if there are issues with DNS or CIFS, but are not essential.
