Thanks.
Another small question (sorry..) about this case.
For example, we could have
10.50.0.0-10.50.255.255 domain\username
10.150.0.0-10.150.255.255 workgroup1 .\username2
10.250.0.0-10.250.255.255 workgroup2 .\username3
The ip scanning check all these ranges.
The active scanning scans the first range because it can retrieve the machine list from the domain; for the second and third case, we need to launch lsclient.exe on the PCs, no other way to scan the "out-of-domain" automatically (even if the ip scan scans the range), right?
Regards
