(As >identified by Paul Ashton in a prior submission to NTBugtraq) There are also a number of entries corresponding to previous logins by users. There is a way to turn this behavior off, but I don't recall at the moment exactly what it is. Essentially, it is there to allow you to log on if the domain controller can't be reached. I believe it stores hashes rather than clear-text. The RAS functionality can often be annoying as well - it tends to prompt me for my password even when I'm using a script (which of course contains the user-password pair in the clear). Not sure why it thinks it needs it - I just leave it blank, but a less astute user would probably type in their actual password.
