@richb-2 - fair point, but there's a clear difference between a locksmith and a burglar - I definitely wear a white, not black, hat.

@jeff Moden - Following on from above - it does prove that 2005 is hackable and I believe 2008/R2/2012 is immune from at least one of these approaches since BUILTIN\Administrators is not included as a default login at installation time. I had to implement these approaches when my employer took on a contract where the previous IT incumbent had left abruptly, not bothering to leave behind password lists, and the client didn't have these. In this case there was a legitimate reason for forced entry.
