Been playing around with 'Passfiltex.dll' which can be downloaded from the this link provided by Ryan Ries. Noticed that some passwords are always get passed instead of getting filtered. Like this one: Pa55w.rd or P@55w.rd.
Have you tried this DLL before and experienced something similair?
For second question, what are your thoughts of using downloadable 'Troy Hunt' password DB which size is almost 11 GB now? It's kind of unacceptable to have a 11GB file in system32 and check all the passwords with that file (Performance?), but what do you think? Also, the file contains the hash instead of the clear passwords. So not sure if we can feed the DLL with that file or not.
