I mentioned passfilt.dll because if I want to enforce an alphanumeric
password I would need to do that.
In Win2K you have option to select the length of characters and that's all.
I mean, if you select 6 characters, as you mentioned "123456" or "aaaaaa"
would be acceptable, and that's is a bad thing. If password complexity is
too much, at least something like "a123456" or "1aaaaaa" would be stronger,
I think.
