Starting nmap V. 3.00 ( www.insecure.org/nmap )
Note: Host seems down. If it is really up, but blocking our ping probes, try -P0
Nmap run completed -- 1 IP address (0 hosts up) scanned in 30 seconds

thats the msg I get
it seems that every option I try i get that
I've tryed with the -P0  but it just the same thing
this is on a XP OS
any help would be great
