We have the premium version which I just upgraded to the latest and greatest. We have 2 untrusted domains and after much ado am able to scan and see new computers in the other domain. When I try to run actions from my PC they fail with access denied to machines on the other domain. Now when I run them from the server most of them work. The server and my PC are on the same domain. It appears that alternate credentials do not work unless you are on the server?
I am also not sure what I did to make it work again.
