'Anonymous Logon' is one of the built-in security groups on Wndows XP Pro
and Home Editions. The 'Anonymous Logon' group could be used for
legitimate purposes such as printing over the local network and other
network-based services. Microsoft has made some slight changes to the
function of this group to improve security. Starting in Windows XP the
Everyone group does not contain the security identifier (SID) "Anonymous."
Therefore, users or services that attempt to access an object anonymously
on a Windows XP-based computer are not granted access if the access control
list (ACL) on the object includes the Everyone group. Anonymous access is
only granted for objects whose ACL explicitly contains the anonymous SID,
which is less common.

| I have a home network in which I share folders and drives. I've recently
begun using broadband, and just checked my security event for the first
time. I noticed numerous successfull logon/logoff by "anonymous logon" at
times that I wasn't loging on or off. I had not checked this prior to
getting broadband.
Does this mean that someone or some program is logging onto my system in
some way? And if so, is there a way to prevent this from occurring?
