Hi
Refer to
273499 Description of Security Event 681
http://support.microsoft.com/?id=273499
This is probably just a user making a typo when they attempt to authenticate
to the IIS server (assuming you require them to authenticate). If you're
seeing a lot of these per second, the issue is likely to be process driven
and probably warrants further investigation.
Kind regards
