Another Windows issue (I guess): If I create a new policy, and enter 
"credentials", the window gets screw (same text is duplicated upper and 
down, using "half" a font :)).

Qs:

1.- If I check the three marks (icmp, tcp, arp), I suppose the host will 
only be detected as dead when the three tests fail, am I right?
2.- When a host is detected as dead, is it right to assume that all modules 
(ping_host.nasl, dont_scan_printers.nasl, etc) got a failure? In other 
words, the host is alive when at least one of the modules thinks so (some 
kind of "OR" logical operation), and it is dead when all modules fail 
(logical "AND"). Right?

No, it's a LAN connection (ADSL). Btw, is there any doc discussing Windows 
vs Linux version differences such as the former one?
