I was doing an auditing and I noticed a called user NT
AUTHORITY\ANONYMOUS LOGIN in account management.
Caller user NAme :Anonymous logon
Caller Domain :NT Authority
What is the explanantion for this? or WHO is this user..
Don't know, he's anonymous

An anonymous user is one that accesses a
resource with NULL credentials, I.e. no username and no password. This
is a system identity to represent such logons - every attempt for access
to an object with null username and password is considered ANONYMOUS
LOGON and you can use it everywhere to grant/deny permissions and user
rights to this type of users. Some older software and services use such
null connections - for example NT 4.0 RRAS uses null credentials to
connect to a DC and check the user's dial-in properties.
