How can someone know Sub-Domains?

[Michelle Konzack]

Hello *,

I have installed inside my corporated domain a subdomain for a  customer
and now this subdomain is under attack, exactly,  the  Domains  with  37
Courier-Servers and 140 Web-Servers are DoS'ed.  This mean,  someone  is
trying to bring down the whole network using >200k  IPs.  I use a  CISCO
12008 which work nicely with its filters, but not always.   My Dual 1 GE
connection is nearly fucked!

And yes, I have a big problem with "extortion" since arround 2 weeks and
I am not willing to pay.

Thanks, Greetings and nice Day/Evening
    Michelle Konzack
