Specifically my problem is with ALockout.dll.
I installed this on my win7 machine and tested it by deliberately locking out an account from my computer.
When I did this though the following file was not generated: %Systemroot%\Debug\ALockout.txt
According to the docs (http://technet.microsoft.com/en-us/library/cc738772(v=ws.10).aspx) the dll is supposed to create this file when an account is locked out from this machine- or maybe I have misunderstood how this works?
