How do I reset individual site permissions for cookies?

[polite person]

Hi
I have set my PC (XP, IE6) so that it asks me each time before loading cookies.
My question is, when I have said that I don't want any cookies from a particular
site, how can I undo this later? Is there a list of "banned sites" somewhere that
I can modify?
Thanks in advance

yes, go to Internet Options>Privacy>Sites.
