Anyone know of a .NET utility that can mimic NT password creation,
obeying certain complexity rules like:

1. Password can't contain any part of email address
2. Password can't contain any part of username
3. Password must have 3 of 4 (letter, number, special character, UCASE
character)

We have one written in a C++ COM Component, but want something native
to the .NET Framework (C# preferably). Hoping to avoid re-writing.

Sincerely,

Bryan
