Idea is to protect automatic logon password. There is the article
(http://msdn2.microsoft.com/en-us/library/aa378826.aspx), which talks about
it. What I was trying to achieve is to remove plain text (DefaultPassword)
from the registry that it can’t be seen.
But at this point I’m not sure what exactly my steps should be in order to
do that ( trying to find more articles, so far not so good).
I might be wrong but it could be that I have to write custom dll in order to
perform auto logon. Any ideas or pointing to some direction are welcome
