So, I finished the first level and at the screen with the stats, it said I didn't find all host and my trace wasn't at zero. I'm curious as to how to find all the hosts. I noticed in desk-11.corporate.com, in the access.log it has two entries of unknowns and then the main.corporate I believe. That file is the only thing I can see as holding information on other host locations since none of the servers had files that even hinted at such. Are their commands I am missing or what?
Also, how does one get to 0% trace? I log into a server and deletelogs, do my business and deletelogs again before I logout. yet I still can't seem to get it done. Killtrace is cool and all but its not worthy of $500, so again, am I missing something?
Please enlighten me. =)

There are hints for every hidden hosts.
They are an optionall objective for the hardcore gamers, and as a result, they aren't really easy to be found ... but they can be found.

As for the trace level, there are level which can't be finished with 0. This is again, an optional objective.
