We ran a web application scan in Qualysguard PCI overnight and it came back saying "no host alive".
Now, I know when I do a discovery scan on IP addresses this means exactly what it says on the tin, but this is a web site so would it really mean that it couldnt reach the site?
The settings we used were
web site address
start scan at /
Form Submission GET & POST
All other options were default.
We had a few sites in the blacklist.
Any ideas would be very greatfully received, I am looking to understand if I did the set up incorrectly or whether it actually was the site down at that time?
