Re: NMAP brings down Exchange Cluster?

Both an interesting and testable assertion! Do these crashes occur mid scan? If so, you could be partially to 
blame(along with whoever configured such a delicate exchange installation). If not, try to give up scanning for a few 
weeks, Nmap is off the hook if more infrastructure problems occur.

The command line parameter you gave are quite benign, and shouldn't be capable of taking down any server. So I doubt 
Nmap it to blame.

Hi nmappers.

Recently, my infrastructure peers have asserted that my use of nmap to scan our data center has caused various 
problems including bringing down FOLB clusters (Exchange servers).  Although I think this is highly unlikely, I 
wanted to get some feedback on this issue.

I am using the following command line switches:

-T3
-sS
-F
-O
-oX

sometimes d4

I appreciate your time.
