Answer : Special character list for strong passwords

So far as I know there is no definitive list as its going to vary with the locale and language and keyboard options set. It basically anything that is not a number or a letter. Mcirosoft define it as. 'Non-alphanumeric (for example, !, $, #, %). extended ASCII, symbolic, or linguistic characters' Depending on your environment, using extended ASCII, symbolic, or linguistic characters in passwords can have unexpected results. It is highly recommended that you test these characters before using them in production.

You can modify the Passfilt.dll file to determine what is and is not allowed if you feel up to it. see http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/security/bpactlck.mspx
