Network-WAN, several servers are auditing successful and
denied logon. In the event viewer under securities, there
are several instances of successful anonymous logon with
event id 538 at all hours of the day and night.

What may be causing this anonymous login when our
firewall prohibits anonymous logon.
 
Are you running IIS with intranet/internet websites allowing anonymous
connections?
