Windows 2000 and file sharing

I have a Windows 2000 Server which is on a domain and 3 clients running XP home so they are not on the same domain. I setup file sharing on the Windows 2000 Server machine and everytime i try and login to the Windows 2000 Server shared folder it makes put in a password for that session. Is there anyway to allow me to not put in a password for every session to access those files?
