Help me, Fearless Readers!

OK, I need a hand here. Does anyone know how to allow a Windows 98 client to connect to Windows 2003 file shares? The Windows 2003 server is on its own domain, and the file shares require a username and password, while the 98 client is in a separate workgroup. There will be a reward for anyone who can help me with this. (Also, if you know how to allow anonymous access to Win2K3 shares, let me know how you do it.)
