WINS or not to WINS??

I have being trying to determine whether I can safely remove WINS from our W2K network. All our clients are W2k or XP and we are using Domino instead of Exchange for e-mail. I have searched high and low for a definite means of determining which applications require WINS but can find very little information. If you have successfully managed to remove WINS from your network please let me know, or if you have decided to keep it I’d like to know why.
