I haven't seen this message before and it only occours once per
computer. What worries me is how the 'User' is NT AUTHORITY\ANONYMOUS
LOGON

Is this something to be worried about?

It is not unusual to see null sessions entries in the security log. The
event below looks like it was to indicate that the computer password was
changed. I would not worry if the computer functions fine and passes the
netdiag test for secure channel which is what the computer password is used
for. I would be more concerned when seeing unexplained logons of user
account that are in privileged groups or repeated logon failures for
privileged group users such as administrator. --- Steve

Thanks for the information. I was worried when I first saw these
messages. The netdiag test turned out fine, so no problems there.

Thanks agian!
