Re: more info on a hopefully unsuccessful compromise

Etaoin,

Is this something specific to your setup, or to the
default Administrator account?

I set up a user account on a Win2K box, and added it
to the Administrators group. I ensured that the
account had no password. I logged into the box using
the test account and no password, and was successful.
However, trying the account name, and then the account
name backwards proved to be unsuccessful.

I agree w/ your sentiment regarding users auditing
systems. In this particular case, there may be
something else going on...the original poster seems to
think he's got three different accounts but they all
have the same name. Also, the OP has stated that the
accounts do not exist in the User Manager, yet goes on
to say that he tried to disable the user account and
couldn't...which would be impossible if it did not
exist.

However, I was not able to replicate the issue.
Anything you may be able to provide could prove
useful.

Thanks,

Harlan
