Javier: Windows XP Professional can support up to 10 simultaneous connections and this is built in, so that this should work just fine for your needs provided you won’t be storing confidential or sensitive information on that windows box. You want to first prepare your windows xp pro box "server" by 1. Set a very strong and complex password on the administrator account. 2. Make sure all the latest updates are installed / set to install automatically, the windows firewall is functional and make sure there is a functional antivirus that is set to scan regularly and get signature file updates. 3. Disconnect machine from network and turn on file sharing, and then going into windows firewall and allowing connections to windows file sharing from only the ip addresses of the two or three mac computers you wish to allow. (note individuals can still spoof an ip address and get past the windows firewall) 4. Run mmc.exe and apply the securews template to secure the settings on the PC. 5. Set your workgroup to something you like by right clicking on my computer -> properties computer name tab -> change button (note the workgroup name) 6. Create users on the windows XP pro box for each mac user with long and complex passwords on your server (record this information as you’ll need it later) 7. Turn off simple file sharing create shares and set permissions on your shares: http://support.microsoft.com/kb/307874 (note the share names) 8. Reconnect the machine to the network. 9. Go to a command prompt and get the ipaddress of the xp box by starting a command prompt typing ipconfig <enter> or clicking on the support tab for the network card. Now attempt to mount the drive on each of the macs: Start Finder Go Connect to server: enter this in the following format: smb://workgroup_or_domain_name;username@ipaddress_of_windows_box/sharename example: smb://hc;[log in to unmask] When the file server is set up correctly and functioning you will be presented with a screen or dialog box that has most of the connection information filled in. You just have to enter in the password and click save password in keychain. If you have problems connecting then: Go into Local Policies, then Security Options, and ensure the policy entitled "Microsoft Network Server: digitally sign communications (always) is DISABLED This works just fine with Windows 2003 file servers and will work with Windows XP Pro file server too. Provided the preceding local policy is set correctly.
