Possibly you have a user up to mischief. I would check that the administrators
group on that computer is what you expect and change any administrator passwords
being sure new passwords are complex. Scan the computer with SpyBot Search and
Destroy to make sure no keyboard loggers, etc are installed on it. If you are
using weak passwords and no firewall or misconfigured firewall, this kind of
activity can even come from the internet. You can go to
http://scan.sygatetech.com/ to do a basic firewall vulnerability test. I would
also enable auditing on logon events to see if there is administrator access to
your server when there should not be by viewing the security log in Event
Viewer. See the link below for details. --- Steve
