Hi Guys,

Thanks to all who responded to my email (question).
AFAIK, my IIS server was patched with SP6a and
cummulative patch for the IIS.

I installed also on my linux box (apache+frontpage
extension) and I got the same attacked but the payload
say that "connection closed". It is annoying because
in ISS payload in Acid it showed my External IP Add.
and I dont know if this successful or not.

Thanks again for the insight of this matter.

I'm completely blind because It does not log it on my
IIS LOG. Tell you frankly I'm not expert on IIS.

Any tips to improve my security on my win nt box will
be highly appreciated.

Your brother in Snort.
