Not saying i've done any lookup on the flag or anything, but i know of
a local security policy setting that exists that says that user
accounts without passwords can only have console logon (log on
locally). Doesn't explain why you can't access the machine without a
password via SM. I believe network logon is controlled through the
user rights assignment in the local security settings (or domain if
you're networked) on a per user basis that can be set to allow/deny
remote access to the machine to specific users. It also can be
controlled through network access in the security options tab. There
is one setting that is turned on by default with simple file sharing
that says all network access is performed as user guest.

Hope that gives you some hints.
